10kA 132kV Porcelain housing station type Surge arrester

Description

Distribution type surge arrester is designed to serve in distribution system and provide over-voltage protection. The varistor used in the arrester is subjected to a series of physical and electrical tests to ensure the protective ability, and the high-level housing verifies the insulating properties. The arrester has been designed and type tested according to IEC60099-4:2004 standard.

Keystone:

The zinc oxide surge arrester is the most advanced over-voltage protector in the world. Due to make the resistor disc

of core component mainly adopt zinc oxide arrester. Compared with the conventional siliconcarbide arrester, this prescription of the product improves greatly the volt-ampere characteristics of the resistor disc and increase through-current capability at over-voltage so as to bring a rad local-changes for the characteristics of the arrester.

Application:

The metal oxide arrester which applies to protect the power equipment like transformers against systerm overvoltages and lightning surges.

Service conditions:

1. Ambient temperature: -40 ~+40°C
2. Height about sea level:  ≤1000m;
3.Power supply frequency:48-62HZ
4. Earthquake intensity: not exceed richter 7.0  degree;
5. Maximum wind veiocity: ≤ 35m/s
The long-term power running voltage should not over the continus operating voltage.
The Altiplano or Contaminated area should be indicated.
