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 a specific customer group, with excellent parameters, high performance, and the ability to open.
The LK-10 series of open-type current transformers are suitable for current measurement, power extraction, and micro-computer protection in complete sets of equipment in AC power systems up to 35kV and 10kV. These transformers feature a compact size, lightweight, ease of opening, and easy installation, making them widely used in compact, fully insulated ring main switch cabinets. They are installed directly onto pre-connected incoming and outgoing cables, offering a simple and quick setup. 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, and South Korean SS, as well as in modular substation and cable junction boxes.
This type of current transformer utilizes high-permeability imported silicon steel sheets as the magnetic material, featuring a split-core and low magnetic circuit loss. Its semi-circular 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. During installation, simply place the two semi-circular cores on the phase-separated cable, secure them with a clamp, and integrate them with the cable for a harmonious and aesthetically pleasing appearance. Suitable for 10kV and 35kV cables with cross-sectional areas of 35mm² to 400mm².
Based on varying current ratios, accuracy grades, and rated loads, this series of current transformers is divided into the following types. Specific parameters can be found in the corresponding parameter tables for each model. (Note: Customized series current transformers with different specifications and parameters can be ordered according to customer requirements.)
