LC1-10 Through-core Current Transformer

The LC1-10 type core current transformer features compact size, high precision, and easy installation. It is particularly suitable for the installation requirements of modern ring main cabinets, achieving compactness, aesthetics, safety, and reliability. This transformer can also pre-allocate installation brackets according to customer needs, allowing for bracket installation.

Through-core current transformer

The LC-10 high-precision current transformer is suitable for current, energy measurement, and protection of electrical equipment in AC power systems with cable lines of 35kV and below. This current transformer features compact size, light weight, and ease of installation, and is widely used in series compact all-insulated ring main switch cabinets such as SafeRing/SafePlus, RM6/SM6, SVS, GA/GE, FB, SS, and FTR.

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

The toroidal core and secondary winding are vacuum impregnated with high-quality epoxy resin in a flame-retardant plastic shell, ensuring moisture resistance, stable performance, and no maintenance required. This type of current transformer is compact, lightweight, and takes up minimal space. It can be mounted in the cable room of a ring main switch cabinet, with installation requiring only the cables to pass through the inner hole, making it simple, quick, and aesthetically pleasing. (Note: Customized series of current transformers with different specifications and parameters can be made according to customer requirements.)

Rated current ratio, accuracy class, and rated load are as shown in the table below, with a rated secondary current of 5A or 1A.
