35kV metal oxide surge arresters

35kV series of metal oxide surge arresters is a system used to protect 35kV power transmission and distribution equipment, capacitors, transmission lines from the atmosphere over-voltage and over-voltage protection of electrical damage.

Metal Oxide Surge Arrester by the main elements of the series and insulated base and other components. Internal body components using nonlinear metal oxide varistor as a core component, it has excellent voltage characteristics. When the system when the atmosphere over-voltage or over-voltage operation, low resistance resistors showed that the residual pressure is limited surge arrester allowed value, while absorbing over-voltage energy to provide reliable protection for electrical equipment. Surge arrester at normal operating voltage, the varistor resistance was high, the current flowing through the small surge arrester, the system plays the role of the insulating spacer.
Composite jacket surge arrester high quality silicone rubber as a raw material, so that the products are small, light weight, explosion-proof performance greatly improved, the inherent hydrophobicity of silicone rubber it has a good stain resistance.
Porcelain jacket surge arrester with a pressure relief device, the internal pressure increases when the surge arrester failure, explosion-proof device movement, release the internal pressure. Arc transferred from internal to external, external form in porcelain sets short, no guarantee porcelain burst.
