35kV heat shrink power cable intermediate connector manufacturing technology method

Abstract

The invention discloses a 35kV heat shrink power cable intermediate connector manufacturing technology method comprising the following steps that an external sheath, an armor and an internal sheath are cut; cable phase splitting is performed, and excessive cable wire cables are sawed; a copper shielding layer and an external semi-conductive layer are cut; wrapping of stress control glue is performed, and heat shrinkage of a semi-conductive stress control tube is performed; wire core tail end insulation is stripped, a "pencil stump" is cut and sharpened, and an internal semi-conductive layer is reserved; tube material and a copper shielding mesh sleeve are sleeved in turn; crimping of a connecting tube, wrapping of a shielding layer and additional wrapping of an insulating tape are performed; heat shrinkage of internal and external insulating tubes and a shielding / insulating composite tube is performed; wrapping of a waterproof adhesive tape and a semi-conductive tape is performed; the copper shielding mesh sleeve is fixed, and the copper shielding layers of the two ends are connected; three phases are tightened, heat shrinkage of the internal sheath is performed and the armor layers of the two ends are connected; and a metal sheath and an external sheath tube are fixed. The technology method has instructiveness and can give clear processing steps to work personnel so that the manufactured intermediate connector is enabled to be high in percent of pass, excessive waste can be avoided and cost can be saved.

Description

technical field [0001] The invention relates to a manufacturing process of electric equipment, in particular to a manufacturing process method of a 35kV heat-shrinkable power cable intermediate joint. Background technique [0002] The production of 35kV heat-shrinkable power cable intermediate joints is completed only by the experience of the staff. The processing steps are chaotic and have no rules to follow, which often leads to a low pass rate of the output intermediate joints and a high scrap rate, resulting in waste and increased costs. . Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a 35kV heat-shrinkable power cable intermediate joint manufacturing process with guidance and high yield of finished products. [0004] In order to solve the problems of the technologies described above, the present invention comprises the following steps: [0005] 1) Stripping and cutting the outer sheath, armor and inner s...
