11kv current transformer CT

The CT is totally-enclosed structure, epoxide resin casting insulated current transformer. It's designed for current, power measurement and relay protection in AC power system with rated frequency 50 Hz or 60 Hz, rated voltage 10kV and below. It is customers' first choice for high output capacity with high rated thermal current and high rated dynamic current. The way of wiring can be changed under request of customer.

General:

Current transformer is epoxy resin vacuum cast pillar structure, suitable for rated frequency 50HZ, rated voltage 10KV and below power lines and equipment for current, electric energy measurement and relay protection.

Key Feature

The current transformer is composed of epoxy resin and its core is made of high-quality magnetic conductive material.
The primary and secondary winding and the iron core are poured in epoxy resin, the product surface is not sprayed, has excellent insulation and moisture-proof properties, and is easy to clean the surface.
The transformer is wired with reduced polarity.
The base is provided with ground bolts and four mounting holes.
