LC7-10 Through-core Current Transformer

The LC7-10 model through-core current transformer has been enlarged in outer diameter, meeting the higher requirements of customers for ratio and accuracy. This transformer offers higher accuracy and is also suitable for both single-winding and double-winding high-precision current transformers.

The LC-10 high-precision current transformer is suitable for current, electrical energy measurement, and protection of supply and demand equipment in AC power systems for cables at 35kV and below. This current transformer boasts small size, light weight, and ease of installation, and is widely used in series compact full-insulation ring main switch cabinets such as SafeRing/SafePlus, RM6/SM6, SVS, GA/GE, FB, SS, FTR, and others.

This type of current transformer uses a new magnetic material for the measuring winding core, which features high magnetic permeability, lower saturation magnetic induction strength, and excellent stability, ensuring high measurement accuracy and a lower instrument security factor. High-quality imported silicon steel sheets, processed through advanced technology, serve as the core for the protective winding, guaranteeing a higher accuracy limit factor.

The toroidal core and secondary winding are vacuum impregnated with high-quality epoxy resin within a flame-retardant plastic housing, ensuring moisture resistance, stable performance, and no maintenance required. This type of current transformer is compact, lightweight, and occupies minimal space. It can be mounted in the cable room of a ring main switchgear cabinet, allowing for quick and easy installation by simply passing the cables through the inner hole. It is harmonious and aesthetically pleasing. (Note: Customized series of current transformers with different specifications and parameters are available upon customer request.)
