1. Like other insulating materials, insulating pipes have excellent flexibility and elasticity, as well as good dielectric and chemical resistance, so they are suitable for wiring insulation and mechanical protection of motors, electrical appliances, instruments, radios and other devices.
2. The insulating pipe usually uses oil or gas as the insulating medium, and is generally made into transformer bushing or circuit breaker bushing, which is commonly used for voltage levels below 35kV. The inner cavity between the conductor of the insulating pipe and the porcelain bushing is filled with transformer oil for radial insulation. When the voltage exceeds 35 kV, the conductor shall be sheathed with insulating pipe or cable to strengthen insulation. It is mainly used for ultra-high voltage transformers and circuit breakers.
3. The use of insulating pipes can also greatly reduce the corrosion damage of equipment wires and other accessories, and also promote the extension of the service life of equipment. Capacitive insulating sleeve is one of them. When the capacitor core is made of adhesive tape, its mechanical strength is high, it can be installed at any angle, its moisture resistance is good, its structure and maintenance are simple, it does not need to lower the sleeve, and its lower end can be turned into a short tail type to reduce its size.
4. This insulating tube is different from others. It uses oil paper as the capacitor core, and generally has a lower porcelain bushing. The lower part is large, sensitive to moisture, and has high sealing requirements; The advantages are that the insulation materials and processes are easy to solve, the dielectric loss is small, and the partial discharge performance is good.
Insulating pipe is a general term There are fiberglass insulation sleeve, PVC sleeve, heat shrinkable sleeve, Teflon sleeve, ceramic sleeve, etc
Yellow wax pipe is a kind of glass fiber insulating sleeve, which is made of alkali free glass fiber pipe coated with modified PVC resin and plasticized. It has excellent flexibility and elasticity, as well as good dielectric and chemical resistance, and is suitable for wiring insulation and mechanical protection of motors, electrical appliances, instruments, radios and other devices.
There are two types of conductor structures of commonly used insulating pipes, namely cable threading type and guide rod type. The cable threading type uses the outgoing cable of the transformer to directly pass through the bushing, which is convenient for installation. When the working current is greater than 600 A, it is difficult to install the cable type structure, and generally the guide rod type structure is used.
