Embodiment Construction

[0018] The manufacturing process of the 35kV heat-shrinkable power cable intermediate joint of the present invention comprises the following steps:

[0019] 1. Stripping and cutting the outer sheath, armor and inner sheath:

[0020] (1) Stripping and cutting the outer sheath: It should be done twice to avoid loosening of the steel strip of the cable armor layer. Leave the outer sheath of the cable end for 100mm first. Then peel off the outer sheath according to the specified size, and the fracture is required to be flat.

[0021] (2) Sawing off the armor: Bind the copper wires on the armor according to the specified size or fix it with a clamp. The winding direction of the binding wire should be consistent with the winding direction of the armor, so that the armor will become tighter and tighter without loosening. Use Ф2.0mm copper wire for binding, 3-4 turns per track. When sawing off the armor, the depth of the circular saw marks should be uniform, and must not be sawed t...

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...
