Specifications

INTRODUCTION
LZCK series split core current transformer is suitable forcurrent measurement and microcomputer protection of
electrical equipment in 10KV and 35KV AC power system.It is widely used in compact fully insulated ring network
switchgears such as ABB-Safe Ring/Safe plus...and cable distribution boxes.The transformer can be directly
installed at the inlet andoutlet cables.The slice is imported silicon material. Thesemicircular ring core and
secondary windings arevacuum poured by insulated resin.
