State grid casting indoor current transformer

General:

State Grid cast series current transformer is mainly used in indoor, for rated voltage of 0.5kV and below, rated frequency of 50Hz AC circuit as current, electric energy measurement or relay protection. The product is epoxy resin cast completely enclosed, widely used in power distribution panel, switch cabinet and electronic instruments. It is easy to install, can use the bottom plate fixed two kinds of installation, beautiful appearance, product performance in line with GB1208.

Key Feature

• The core of the current transformer is circular and rectangular

• The secondary windings are distributed around the iron core and are cast with epoxy resin as the shell of the current transformer. The current transformer is designed as a window hole for the primary busbar or cable to pass through

• P1 is marked as the first entry end; P2 is marked as the primary outlet end; The secondary current flows out from S1. S2 is the inflow end, which is the decreasing polarity.

• The iron core is formed by silicon steel sheet and microwafer winding, no air gap, high magnetic properties, secondary winding uniform winding, small magnetic leakage, with high temperature resistance, moisture resistance and other functions, stable performance advantages, cover box two holes with anti-theft electrical measures.

Technical Data
