The LCWB5-35 current transformer is a porcelain box type oil paper insulated fully sealed structure with an "8" - shaped body. It consists of two circular secondary windings combined together and then wound through its window to form a primary winding. The main insulation is composed of the insulation of the primary and secondary windings. The body is mounted in a porcelain sleeve and fixed on the base. The porcelain sleeve is equipped with an oil storage tank. The primary outgoing line is led out from the oil storage tank, and the secondary outgoing line is led out from the base through a porcelain sleeve.
