CEE-YJZWCF-64 / 110KV, 76 / 132KV series of composite casing outdoor terminal to meet the IEC60840-2004, GB / T11017-2002 and other related technical requirements, the outer insulation is a glass fiber is a glass fiber reinforced hollow epoxy Resin tube, covered with insulated silicone rubber skirt outside the composite casing, both ends of the use of aluminum alloy flange seal. The casing is filled with insulating silicone oil. The stress cone is molded with EPDM rubber and has reliable performance. Twenty sets of springs with permanent force are used to tighten the stress cone into the interior of the cone by means of a taper so as to ensure that the cone of the stress cone is in close contact with the outer semiconducting layer of the cable and that the stress cone is effective with the insulating silicone oil Isolation, to prevent the stress cone immersed in silicone oil in the aging and electrical properties decline. Through the grounding (protection) box to reliably ensure the terminal to ensure long-term safe operation.

According to the site installation environment pollution level requirements are different, the composite casing outdoor terminals are applicable to the class Ⅲ and Ⅳ two kinds of products.

At present, the external 110 ~ 345kV voltage level with the main type of cross-linked cable terminal for the prefabricated rubber stress cone terminal (referred to as prefabricated terminal), higher voltage grade cross-linked cable terminal using silicone oil impregnated film capacitor cone terminal (referred to as the capacitor cone terminal ). Early in the 110kV voltage level has been used around the other types of terminals, and now has been rarely used.
