LK12-10 Open Type Current Transformer
LK12-10 Open-Type Current Transformer, featuring a height of 100mm. Secured by a single stainless steel collar for easy opening and installation, it boasts excellent performance and reliability.
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 of 35kV and 10kV or below. These transformers feature compact size, light weight, openability, and ease of installation, making them widely used in compact, fully insulated ring main cabinets. They are simply mounted directly onto the pre-connected incoming and outgoing cables, ensuring quick and convenient installation. They are extensively applied in compact, fully insulated ring main 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 type of current transformer utilizes high-permeability imported silicon steel sheets as the magnetic core material, featuring a separable iron core and low magnetic circuit losses. Its semi-circular ring-shaped iron core and secondary winding are vacuum impregnated with high-quality epoxy resin within a flame-retardant plastic shell, which prevents dampness and ensures stable performance with no need for maintenance. During installation, simply place the two semi-circular rings onto the phase-separated cables, secure them with a clamp, and they will be integrated with the cable for a harmonious and aesthetically pleasing appearance. Suitable for 10kV and 35kV cables with cross-sectional areas of 35mm² to 400mm².
The series current transformers are divided into several types based on different current ratios, accuracy levels, and rated loads. Specific parameters are detailed in the corresponding specification tables for each model. (Note: Custom series current transformers with various specifications and parameters are available upon customer request.)
