Current transformer is an epoxy resin cast insulated completely enclosed product, suitable for power systems with rated frequency of 50HZ or 60HZ and rated voltage of 10KV or below, for electric energy measurement, current measurement and relay protection.
General:
The current transformer is an indoor epoxy resin cast pillar type full-working condition product, which is used for relay protection or electric energy measurement in the power system with rated frequency of 50hz and rated voltage below 10kv.
Key Ferature
The product is a completely closed structure, using indoor epoxy resin vacuum casting, with arc resistance, UV resistance, aging resistance and other characteristics.
The shape adopts anti-umbrella group, and the surface creepage distance is large.
The secondary terminals are sealed with a metal protective cover to prevent rain, dust and corrosion.
