long life high voltage 69kv 132 kv 138kv 220kv composite polymer disc suspension insulator

Composite suspension insulator:

The composite suspension insulator is composed of glass fiber epoxy resin core, silicone rubber shed and metal fittings. The silicone rubber shed adopts integral injection and compression technology, thus solving the key problem of interface electrical breakdown that affects the reliability of composite insulators.

The coupling between fiberglass core and metal fittings adopts advanced pressure welding technology, it equipped with automatic acoustic detection system, it's in high strength, beautiful appearance, small size and light weight, the galvanized metal fittings is in anti-corrosion, the insulator can be used interchangeably with the porcelain insulator, with the reliable structure, the product won't damage the core and can give full play to its mechanical strength.

Conditions of use:

1.Ambient temperature: -40°C to +40°C

2.Altitude: no higher than 1500 meters

3.AC power frequency: no more than 100HZ

4. Maximum wind speed: no more than 35 m/s

5.Earthquake intensity: no more than eight levels
