Perfect Insulation Power Distribution Terminal Block
Product description:
According to the power grid upgrading plan,in order to improve residential electricity utilization condition,the company developed the multi-circuit output terminal block for branch lines of service-entrance wires in the light of market demand.The products have been popular with the electric energy measuring operators since being launched on the market,they not only are convenient to operate,but also guarantee fastness and reliability of wiring,finally reach the aim of safety in utilizing electric energy,actively promotes the standardization and normalization of metering device.
This series of products has passed the China compulsory certification,the technical indexes are in conformity with national standard GB14048 and international standard IEC,now the products are widely popular ized by the power department.
Structure features:
Featured with small volume, large current carrying capacity,high withstanding voltage,reasonable structure,nice appearance,etc.,this product has many superior properties such as flame retarant,withstanding high temperature,no water absorption,wetness prevention,perfect insulation,impavt resistance,anti aging,etc..
It's cover plate is made of transparent material,assembled and disassembled conveniently,so,it attains the goal of transparence and visualization as well as reliable power utilization.
Application:
This product supports meterring of various meter-position,sfter mounting,it not only avoids the problem of weak current,unsafe, inconvenience or other potential accidents caused by service-entrance wire entering into bare directly,but also cuts down the cost of metering box.It can be divided into one-outlet,two-outlet,three-outlet,four-outlet...twenty-four-outlet and so on according to the outlet wire condition.
