Product Description

LZCK2500-10 800/5A 35KV SPLIT CORE ZERO SEQUENCE CT CURRENT TRANSFORMERS

Introduction
The Model LZCK2500-10 zero phase ct is a ring-type resin-casting split core current transformer. Some clients also called it TTCC. This model can be used both for measurement and microcomputer protection of electrical equipment in 11KV and 35KV AC power systems of ring network switchgear such as ABB-Safe Ring/Safe Plus...and cable distribution boxes.
We used imported silicon material and using our mature advanced producing technology we make sure our transformer has very good linear and more than 20 years of using life to be qualified for all the jobs. The semicircular ring core and secondary windings are vacuum poured by insulated resin. All of our current transformers are strictly comply IEC60044-1, IEC 61869-2, NTC 2205, GB1208-2006, GB20840.2-2013, ANSI/IEEE C57.13.
