11KV Resin Cast Split Core Current Transformer , Low Voltage Current Transformer Outdoor
Resin 11KV Split Core Current Transformer Outdoor High Quality
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 and outlet cables. The slice is imported silicon material. Thesemicircular ring core and secondary windings arevacuum poured by insulated resin.
Features
The current transformer with high strength PVC shell, all cast bus structure. Transformer directly stuck in the cable Three rubber rings to resist the cable and cable with one. Transformer core using high-quality silicon steel roll, the second wire wound evenly on the core. Transformer open structure can not cut off the cable installation
