Polymeric Housed Zinc Oxide Lightning Arresters Without Gaps (3-36KV)

Nominal discharge current: 10KA

Voltage range: 3-36KV

Accessories: Mounting bracket, dis-connector, earthling cable.

Condition of Use
This product is used in the exchange of 220KV and below power generation, transmission, substation, distribution systems, and systems for the internal operation of the lightning over-voltage amplitude is limited to a predetermined level, the whole system insulation system with basic equipment. Meanwhile, the product can’t be used to limit the resonance over-voltage, harmonic elimination systems need to adopt other ways.
