Product Description

- Commodity name: Composite-Housed Metal-Oxide Surge Arresters Without Gaps
Gapless Metal Oxide Arrester with Composite Coating (hereinafter referred to as arrester) For AC power systems, the arrester is used to restrain system overvoltages and protect power transmission and transformation equipment against overvoltage. It is mainly composed of the high-voltage terminal, metal oxide varistor, external insulation, low-voltage terminal, and lower flange. The external insulation is high-temperature vulcanized silicone rubber (HTV), which is integrally injection-molded. The low-voltage terminal of the arrester is used to connect to the on-line monitor or discharge counter. The high-voltage terminal of arresters with a rated voltage class of 192kV and above is equipped with a grading ring. Operating Environment - Minimum temperature: -35°C - Maximum temperature: +45°C - Daily average temperature shall not exceed: +35°C - Monthly average maximum relative humidity: 95% (at 25°C) - Maximum wind speed: 34 m/s - Can be designed according to users' special operating conditions. Performance Characteristics 1. Reasonable internal structural design ensures uniform potential distribution; 2. High insulation level and high operational reliability; 3. Strong hydrophobicity and excellent pollution resistance on the external insulation surface; 4. Excellent in nonlinearity and protection level.
