LK9-10 Open-Type Current Transformer
LK9-10 Open Type Current Transformer, featuring an inner diameter of 50mm and an outer diameter of 135mm. Custom mold designed for specific customer groups, with good parameters, high performance, and the ability to open.
The LK-10 series open-type current transformers are suitable for current measurement, power extraction, and microcomputer protection in complete sets of equipment in AC power systems up to 35kV and 10kV. These transformers feature compact size, light weight, ease of opening, and easy installation, making them widely used in compact fully insulated ring main switch cabinets. They are simply mounted directly onto pre-connected incoming and outgoing cables, offering a quick and convenient installation. They are extensively applied in compact fully insulated ring main switch cabinets such as ABB-SafeRing/SafePlus, Schneider RM6/SM6, Eaton SVS, German GA/GE, French FB, South Korean SS, and also in modular substation and cable junction boxes.
This current transformer model uses high permeability imported silicon steel sheets as the magnetic guiding material, featuring a split-core iron core and low magnetic circuit loss. Its semi-circular ring iron core and secondary winding are vacuum impregnated with high-quality epoxy resin in a flame-retardant plastic shell, providing moisture resistance, stable performance, and no need for maintenance. Installation involves inserting the two semi-circular rings onto the phase-separated cables, securing them with a clamp, resulting in a harmonious and aesthetically pleasing assembly. It is suitable for 10kV and 35kV cables with cross-sectional areas from 35mm² to 400mm².
Based on different current ratios, accuracy classes, and rated loads, this series of current transformers is divided into the following types. Specific parameters are detailed in the corresponding parameter tables for each model. (Note: Customized series current transformers with different specifications and parameters can be made upon customer request.)
