Corona suspension coil for ADSS cable
Installing ADSS cables on or above 110KV transmission lines may cause electrical corona at the teminal. To solve the problem, we specially design a corona proof ring, which can significantly improve the status of electric field at the terminal helical hardware fittings and double the corona causing voltage.
Instruction:
1. Choose appropriate type from specification table according to the cable diameter
2. Each set of hardware is equipped with one corona ring.
Application:
1. Poles/ towers with corner angle of less than or equal to 25° straight lines.
2. The angle of single-side suspensions is between15°-18°.
