Abstract:
Disclosed is a capacitor bushing and a method of manufacturing the same. The capacitor bushing includes insulating layers (20), formed by winding insulating fibers (22) around the outer side of a central conductor (10), and conductive layers (30) between the insulating layers (20). The wefts (34) and warps (36) that constitute the conductive fibers (32) are manufactured by sequentially forming a first coating layer (38) and a second coating layer (38′) on the surface of a core wire (37). The wefts (24 and 34) and the warps (26 and 36) of the insulating fibers (22) and the conductive fibers (32) extend obliquely with respect to the longitudinal direction of the central conductor (10). The wefts (24 and 34) and the warps (26 and 36) form a polygonal or circular shape. The present invention has a merit in that bubbles are prevented from being generated in the filling layers (40).
