Perfect Insulation Power Distribution Terminal Block
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
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.
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.
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
and so on according to the outlet wire condition.
