Ceramic power line insulators

Ceramic power line insulators are always used for high voltage distribution & transmission lines to support and insulate conductors.

Ceramic power line insulators

Types for Ceramic power line insulators:
1. suspension insulator: is designed to link together into strings
2. Pin insulator: usually mounted on a pin on the cross arm and the voltages up to 36KV.
3. line post insulator:

Main characteristics are no puncture, high mechanical strength, excellent insulation and anti-pollution
4. station post insulator: commonly used in substations and related switching equipment
5. railway insulator: have high mechanical strength
6. hollow insulator
7. stay insulator
8. shackle and spool insulator

The electrical test for Ceramic power line insulators have:
◆ Low frequency dry flashover voltage tests
◆ Low frequency wet flashover voltage tests
◆ Low frequency dry withstand voltage tests
◆ Low frequency dry withstand voltage tests
◆ Impulse withstand voltage tests
◆ Radio-influence voltage tests
◆ Visual corona test
◆ Puncture tests

All orient power ceramic power line insulators are produced as per IEC and ANSI and other standards , is wet-process porcelain , have high quality, welcome to contact us for more details!
