HV Silicone Ceramic Housing Type Metal Oxide Lightning Arrester for
Power Distribution Substation
Normal operating conditions for Surge Arrester :
1. The ambient air temperature is no higher than +40°C, no lower
than -40 °C .
2. The altitude above sea level does not exceed 1000m. ( the
plateau area should be indicated when order.)
3. AC system frequency is 50Hz or 60Hz.
4. Power frequency voltage brought to bear on arrester for a long
time does not exceed the continuous operation voltage of the
5. Maximum wind speed does not exceed 35m/s.
6. Te earthquake intensity does not exceed 7 degrees.
7. The pollution area should be indicated.
- It adopts double sealing structure, the core encapsulates by molded
silicone rubber which completely solves the sealing problem of
porcelain housed products.
- It has a two-way pressure release structure.
- Its core component ZnO varistor has good pressure ratio,
consistency, large flow capacity and high reliability.
- E creepage distance of porcelain housed products is wide which is
suitable for IV level heavy pollution areas.
