FCGW composite wall bushing is outdoor-indoor type, suitable for power distribution devices of three-phase AC system power stations and substations with rated voltage of 10KV~35KV and frequency of 15~60Hz. The ambient temperature of the installation site is -40℃~40℃, and the altitude does not exceed 1000m. This product is suitable for horizontal installation. The electrical and mechanical properties of the composite wall bushing meet the standard requirements, and also have the common characteristics of composite insulators. Small size, light weight, beautiful appearance, especially the silicone rubber shed used for external insulation, the good hydrophobicity and hydrophobic migration characteristics of the sheath make the composite wall bushing have good pollution resistance and prevent pollution flashover capability. The composite wall bushing is composed of a cylindrical guide rod and an epoxy fiber layer that tightly wraps the guide rod, an intermediate flange, and a silicone rubber sheath and an umbrella skirt that encapsulate the epoxy glass fiber layer. The electric field is carried out in the intermediate flange area. Treat evenly. This series of products is produced according to Q/GND-JD05-2003, and complies with the relevant regulations of GB/T12944.1-1991, GB/T12944.2-1991 and J85892-1991
