Applications of fiberglass pipes
2025-04-16
Application examples for some household electrical appliances or electronic devices using fiberglass casing:
Fiberglass tubing is widely used, from household bundles and home appliances to the aerospace industry.
- Applies to lighting lamps
A good lighting coil can be used with a building until it is removed, so insulation protection for many coils is very important. The voltage level of commonly used coil lamps is below 300V, and the operating temperature is not high. The insulation layer of the bundle itself basically meets the insulation conditions and may not require additional insulation protection, but its service life is limited. After 5 years, the coil bundle is exposed to surfaces and is susceptible to aging and corrosion. In the long run, this can easily lead to an accident. People can use heat shrink tubing for protection. Heat shrink tubing is cheap and has relatively good insulating and sealing properties. However, heat shrink tubing requires heat and compression, and the shrink temperature can directly damage the insulating layer of the coil bundle itself. Thus, uncompressed casing (such as fiberglass tubing) becomes the choice for protecting the coil insulation.
Compared with heat shrink tubing, this fiberglass casing has become preferred. Fiberglass tubes have excellent parameters such as pressure resistance, high temperature resistance and corrosion resistance. Putting glass fiber tube into the coil bundle can protect the coil bundle well and prolong the service life of the coil.
2.In this section, the editor describes the application of fiberglass casing in ring transformers
Ring transformers have good output characteristics and anti-interference ability, and are widely used in fields such as computers, medical equipment, telecommunications, instrumentation and lighting.
Conventional ring transformers standard series power transformers range from 8 to 1500W, with slight pressure regulation, the full operating temperature is only 40°C. It can handle short-term overload and is suitable for high demand applications. Class B (130°C) polyester insulation is used between the first and second windings, which requires at least three layers of insulating tape to withstand the 4000V AC 1 min compression test. With the advancement of technology and the updating of relevant standards, insulating tape has been replaced by fiberglass pipes. At present, most ring transformers on the market use fiberglass pipes to protect the insulation, most of which are 4kV fiberglass pipes. Among them, the most commonly used are inner rubber outer fiberglass pipes and inner rubber outer fiberglass pipes.
3.The car starter uses three parts to realize the entire starting process.
The DC motor draws current from the battery so that the starter drive gear generates mechanical movement; The drive mechanism meshes the drive gear with the flywheel toothed ring, the engine can be automatically separated after starting;
The turning on and off of the starter circuit is controlled by an electromagnetic switch. Among them, the motor is the main component inside the starter. The car starter is an important part of the car and cannot be easily damaged, but in order to extend the life of the starter, it is also necessary to protect the car starter and use it properly.
The wiring harness in your car's starter is one of the parts that is susceptible to corrosion and aging and damage, so it is especially important to protect the starter wiring bundle.
Because of its self-extinguishing, soft, arc, corona, wear and stress resistance, corrosion resistance and aging resistance, fiberglass tubing has become the first choice for insulation protection of the bundle of automobile starters.
To protect the environment, all starter materials must be free of substances such as asbestos and cadmium metal. Fiberglass pipes comply with RoHS environmental standards and fully meet the requirements of the automotive industry.
- Fiberglass pipes are widely used and are also widely used in automobiles. For example, fiberglass tubing is used in motor coils for new energy vehicles, fiberglass regulates batteries for new energy vehicles, and fiberglass is used in automotive bundles. Fiberglass tubing is used in automotive oxygen sensors.
Pure electric new energy vehicles no longer have tailpipes, but hybrid new energy vehicles still have tailpipes. The automotive oxygen sensor is a key feedback sensor in the electronic fuel engine control system. They are key components for controlling vehicle exhaust emissions, reducing vehicle pollution, and improving the combustion quality of vehicle engines. The oxygen sensor is installed on the engine exhaust pipe. If the oxygen sensor fails, the electronic fuel injection system computer will not be able to obtain information about the oxygen concentration in the exhaust pipe and, therefore, will not be able to control the air combustion ratio with feedback, which will increase fuel consumption and engine exhaust pollution, the engine will have unstable idle speed, fire, surge and other malfunctions. The ceramic of the oxygen sensor is hard and brittle. If it is hit by a hard object or blown by strong air flow, it may break and fail.
Protection requirements for automotive oxygen sensors require improved degradation resistance and breathability. At the same time, they must be resistant to high temperatures and corrosion. Fiberglass pipes are woven from alkali-free fiberglass yarn and resin and processed at high temperatures. Fiberglass tubing used in automotive oxygen sensors uses a horizontal weaving method and is the first choice for insulation protection.
- Firstly, new energy automobile engines have high temperature requirements, but also require certain wear resistance, sharpness and mechanical toughness. Fiberglass tubes have become the first choice of insulating casing for new energy vehicles. The new car engine will widely use 1.5KV fiberglass casing pipes, 4KV fiberglass casing pipes and high temperature silicone heat shrink pipes, of which high temperature stationary braided pipes are also widely used. New energy car bundles will also use a small portion of fiberglass tubing for insulation and protection.
Requirements for glass pipes for new cars:
Ecology is the main standard for new energy vehicles, followed by fire-resistant standards for fiberglass pipes, which generally must meet fire resistance class V0.
- When the engine is running, there is usually a bundle of wires and a motor connection. The wires commonly used in motors on the market are high temperature wires, which usually withstand temperatures of 125°C or above 150°C. While the electric beam uses high-temperature wires, losses and corrosion remain serious in long-term high-temperature and vibration operating environments. Electrical bundles are usually lined with fiberglass tubing, and some even use high temperature wires made directly from fiberglass. Fiberglass pipes are waterproof, oilproof, and windproof. Anti-pollution, prolonging the service life of equipment, silicone rubber glass fiber tube has strong chemical stability, silicone does not react with oil, water, acid, alkali and other substances, within 260°C, can be used for a long time without aging, the service life in the natural environment can reach decades, which in these cases can maximize the protection of pipelines, cables and equipment, greatly extend its service life.
7.Both small fan motors and mid-size car motors have more or less coils in which fiberglass tubes are visible. What is the role of fiberglass?
Our first reaction is isolation and protection. There will be wires in the coil. Covering the wires in the engine with fiberglass tubing can improve the insulating properties of the wires. At the same time, fiberglass tubes have higher heat resistance than conventional wires and cables.
In fact, fiberglass tubes in motor coils have purposes other than insulation, heat resistance and wear resistance. This is a permanent role. The fiberglass tubes are entangled in the middle and periphery of the coil, and the most intuitive effect is fixation. Fixed reel: make sure the reel or disc does not move due to high speed; Fixed Wires: Fiberglass tubes are placed on the outer sheath of the wire and then tied to make the wire easier to fix. The choice of fiberglass pipes is mainly because they have higher resistance to pressure and temperature.
In addition to fiberglass pipes, silicone rubber heat shrink pipes are also used to protect the insulation of wire connections.
- The most widely used fiberglass pipes in shipbuilding are inner fiber outer pipes and inner rubber outer steel pipes.
Fiberglass pipes are mainly used in high temperature zone of ship, heating zone cables, liquid pipelines, rolling mill cables, pipelines, saw cables, generator sets, voltage equipment, large buildings, ship wire bundles and exhaust pipes. The main certifications of marine fiberglass pipes are SGS environmental certification and UL fire resistance certification. Products with higher environmental and fire-resistant properties are more favorable for export. The main characteristics of marine fiberglass pipes are: high temperature, insulation, fire resistance, electrical insulation, chemical stability, weather resistance, cold resistance, water resistance, oil resistance, ozone resistance, voltage resistance, arc resistance, corona resistance, etc., particularly safe and environmental properties, is the best alternative to hazardous substances such as asbestos.
Marine fiberglass pipes are moisture-proof, oil-proof, wind-proof, pollution-proof, can extend the service life of ship equipment. Fiberglass silicone rubber tubing has high chemical stability. Silicone does not react with oil, water, acid, alkali and other substances. They can be used for a long time at 200°C without aging. The service life in the natural environment can reach several decades, which allows for maximum protection of pipelines, cables and equipment in these conditions and significantly extends the life of the vessel. According to European distributor Intertec, double fiberglass insulation can replace molded plastic insulation in the armature shaft of a small motor, which can have a significant impact and save engine assembly costs. This double fiberglass insulation pipe was developed by Polygon in Indiana, USA.
According to reports, the insulation pipe is continuously pressed into the wellbore, avoiding the high cost of traditional wellbore insulation, long insulation time and bonding imperfections, while simplifying the process, reducing energy consumption, improving production efficiency. Insulating pipes are made from fiberglass and then impregnated with epoxy or other resin. This material has a low rate of water absorption and can be used for long periods of time in damp environments, which is why cocoa is used in pumps, wet vacuum cleaners and lawn mowers. It can also be used as a material for washing machine pulleys to avoid the electrostatic effect of the pulleys on the performance of the electronic control.
This tubular fiberglass structure has greater torque when driven in both directions by the motor, which cannot be achieved by conventional winding structure.
- The heating panel of an electromagnetic oven creates an alternating magnetic field through the components of the electronic circuit boards. When the bottom of a pan containing iron is placed on the stove, the pan cuts an alternating magnetic field line and creates alternating vortices in the metal part of the bottom of the pan. The vortex causes the iron molecules in the pan to move at high speed and irregularly, the molecules collide with each other and the friction generates thermal energy. It has the advantages of fast heating, high thermal efficiency, no open flame, no smoke, no harmful gas, no thermal radiation to the environment, small size, good safety, beautiful appearance and so on. Fiberglass pipes are made from fiber wires woven into pipes and coated with resin at high temperatures. Can be divided into high temperature stationary braided pipes, silicone fiberglass pipes and high pressure silicone fiberglass pipes.
The power of electromagnetic furnaces is different, and the diameter of the heating plates is different. Generally, the maximum temperature of 1800W electromagnetic furnace can reach 270 degrees. If it's a dry pan, it will burn it red in about 70 seconds. The panels can withstand temperatures of 650 degrees, but do not actually reach that temperature. The thermal panel of the electromagnetic furnace will have a power wire. To ensure safety and compliance, insulating casing must be used for protection. Color online circle. If the quality of the coil is poor, the paint will fall out when heated, causing a short circuit, which can easily cause the pipeline to explode. Fiberglass tubes have temperature resistance and high pressure level above 200°C. It is the first option for electromagnetic furnace heating plate beam insulation protection.
- Application of fiberglass pipes in thermistors.
First, let's understand what thermistors are and why thermistors use fiberglass tubes.
A thermistor is an electrical element whose resistance value changes with temperature. It has the function of temperature control, temperature measurement and temperature compensation. Often used in batteries. Electronic thermometers, drinking fountains, electric kettles and other electrical appliances. For example, there is an NTC thermistor in the pan. When the rice is cooked, it goes into insulation function. This is because thermistors measure temperature and control temperature. The operating temperature of thermistors is very high and varies greatly. The constant temperature device is used in temperatures ranging from -55°C to 315°C. When operating in high temperature environment, the connecting line temperature should reach about 200 degrees Celsius. To insulate the thermistor, ordinary heat shrink tubing is not enough. Fiberglass tubing is one of the best options.
The temperature of fiberglass pipes ranges from -40°C to 200°C. It consists of alkali-free glass fiber woven into a tube, coated with silicone resin, and then subjected to high temperature treatment. It is flame retardant, environmentally friendly, heat insulating, insulating, and is a good partner for thermistor protection.
- Fiberglass pipes are woven from fiberglass into pipes impregnated with silicone resin and treated at high temperatures.
The following describes the use of fiberglass pipes in pizzerias: Pizzerias are mainly used for baking pizza. The maximum operating temperature is about 200 degrees Celsius. Electrical related parts naturally have bundles of wires that require fiberglass insulation protection. The reason for choosing fiberglass tube is that fiberglass tube can withstand high temperatures above 200°C, while having high pressure and wear resistance, making it the first choice for high temperature beam insulation protection.
- Application of fiberglass pipes in bundles for air conditioning.
Glass fiber woven tube has high temperature resistance, excellent mechanical properties, sharpness, corrosion resistance, can effectively protect the beam, prolong the service life of equipment. There are various types of fiberglass pipes used in home appliances, including yellow wax pipes, stationary pipes, breakers, internal fibers, and external rubber fiberglass pipes. The most commonly used in air conditioners is silicone fiberglass tube, which is woven from alkali-free glass fiber into a tube, then coated with silicone resin, and then processed at high temperatures. It has good dielectric properties and good softness, flame retardancy and heat resistance.
Fiberglass protective covers are widely used to insulate and insulate electric motors, appliances, electrical heating equipment, electronics and related wires. Air conditioning bundles are mainly outdoor air conditioner bundles, they are often exposed to outdoor air, wind and rain, easy to corrosion, especially the bundle itself has limited heat resistance, generally around 100°C, so the air conditioner bundle is often covered with fiberglass pipes to further protect and extend the life of the outdoor air conditioner.
