LJKW-10 outdoor open type current transformer is used for current measurement, protection, and control of medium voltage overhead lines of 10kV and below. It does not require wire cutting during installation and can also be installed live. Commonly used in current monitoring and control of high-voltage reactive power automatic compensation devices for overhead power lines.
This type of current transformer achieves no partial discharge by improving the design and manufacturing process based on traditional overhead current transformers. The external insulation adopts a one-time silicone rubber vulcanization process, which thoroughly achieves moisture resistance and UV protection, without the need to install protective covers. It has the characteristics of arc resistance, aging resistance, and long maintenance free cycle.
