  • Insulating Mounting Bracket

    Insulating Mounting Bracket

    Installation Method Instruction 1. Arresters with the Voltage grades of 36kV or under shall be installed with insulation bracket. That’s to say , the arrester is fixed to the Intended Installation place with the Insulation bracket and the disconnector Is Installed on the lower connector terminals of the arrester. The earth connection applies weaved annealed copper wire with the length of about 250mm to ensure enough insulaiion distance when departing from the arrester body. Attention sh...

  • TLB Disconnector

    TLB Disconnector

    As a special supporting product for arrester, the disconnector is series connected with arrester. When ihe arrester comes across any fault, it would operate quicWy and let the failed arrester disconnect from the power grid, meanwhile, it would give obvious disconnedion symbol, so that tie mar> tenance personnel would find the point of failure and change the arrester in time. On the ottier hand, when the arrester works normally, disconnector does not work and is under low impedance state, ...
