LB-220KV High Voltage Current TransformerDetailed product description：

The LB-220KV high-voltage current transformer is an electromagnetic imitation oil tank with a ceramic sleeve structure. It consists of fuel tank, porcelain sleeve, oil storage tank, expander, body, primary outlet device, pressure release device, and secondary outlet box. The primary wire set is in the shape of a "racket" and adopts an oil paper capacitive insulation structure. The transformation of current ratio can be achieved through external series parallel switching using a primary output device, or by switching at the secondary output terminal; The secondary winding is wound around the annular iron core, fitted under the primary winding, and placed in the oil tank. The front of the fuel tank is equipped with a secondary outlet box, the back is a pressure relief device, and the bottom is equipped with a drain valve.
