1,Anti-leakage trace, anti-corrosion, resistance pollution, good hydrophobicity
2,Three-phase Combination Lightning Arrester
Key words : Three-phase Combination Lightning Arrester / Surge Arrester 3 phases / Transient Voltage Suppressor
Companies with a full set of advanced production and testing equipment, product quality in the industry to stay ahead, have passed ISO9001-2000, CE, ROHS certification and so on.
Service conditions:
Ambient temperature:-40oC~+40oCAltitude: not more than 3000mMax wind velocity:lower than 35m/sMax horizontal pull N(The top wire of the arrester):147NLong time force the power frequency voltage to the arrester is lower than the products Continual operating voltage.Excellence in product quality and quality of services, cooperation was more than excellent suppliers.
