Optical cable electrical penetration and processing method thereof

Abstract

The invention belongs to the technical field of electrics and in particular relates to an optical cable electrical penetration assembly and a machining method thereof. The defects of the conventional electrical penetration assembly technology are overcome. The optical cable electrical penetration assembly comprises a linear cable core, wherein a protective casing is sleeved at the periphery of the linear cable core; an inner positioning and sealing piece is arranged on the inner side of one end of the protective casing; an outer positioning and sealing piece is arranged at the end part of one end, where the inner positioning and sealing piece is arranged, of the protective casing; and an insulation protection pouring layer which is made of an insulation protection material and is positioned between an outer wall of the linear cable core and an inner wall of the protective casing is formed between the inner positioning and sealing piece and the outer positioning and sealing piece through pouring. The machining method of the optical cable electrical penetration assembly comprises a positioning and sealing step and a pouring and molding step. The optical cable electrical penetration assembly disclosed by the invention has the advantages of good mechanical property and sealing property, high insulating property and pressure-bearing capacity, simplicity in machining and manufacturing, radiation resistance and aging resistance, and the machining method of the optical cable electrical penetration assembly is simple, convenient and easy to operate.

Description

technical field [0001] The invention belongs to the field of electrical technology, and in particular relates to an optical cable electrical penetration part and a processing method thereof. Background technique [0002] Electrical penetration is one of the key equipment of nuclear power, and it is an important electrical facility that provides power or communication channels for some equipment and facilities inside and outside the containment of nuclear power plants. At the same time, as a part of the containment, it constitutes a safety barrier to prevent the leakage of radioactive materials. The electrical penetration of the reactor containment is used as a channel for various optical cables to penetrate the containment. It must not only meet the relevant electrical performance requirements, but also ensure reliable sealing performance. Even under various accident conditions, the pressure boundary of the containment can still be maintained. integrity and electrical conti...
