The general epoxy pipe adopts the glass fiber cloth roll pipe process, which is suitable for general ordinary insulating materials. The accuracy is not very high.
Machining performance is not as high as epoxy wound pipe.
Epoxy winding is made by impregnating glass fiber with ultra-low viscosity and high temperature resistant epoxy resin and cross-winding under the control of a computer. It is the raw material for the manufacture of composite hollow bushings for high-voltage and UHV SF6 high-voltage electrical appliances and current transformers.
The main characteristics of epoxy glass fiber winding pipe:
The glass fiber reinforced winding structure of the winding pipe and the optimized mechanical auxiliary layer design make the product have high bending strength and excellent mechanical performance, which is suitable for severe earthquake areas.
The epoxy glass fiber wound pipe is added with high temperature resistant resin, which has high temperature resistance, and can be used for hollow casing production under the conditions of high temperature and high pressure in the extinguishing chamber of SF6 high voltage circuit breaker.
The inside of the epoxy glass fiber winding pipe is resistant to corrosion by SF6 gas decomposition products and compounds
Excellent insulation performance, partial discharge is less than 5pC
