Embodiment 1

[0026] The manufacturing method of the benzene hydrogenation engineering high-voltage power cable terminal of the present invention is characterized in that it comprises the following steps:

[0027] a. Strip and cut the cable, cut off the excess length of the cable, determine the length of the cable core, leave 10-15mm of the inner sheath when stripping and cutting the inner sheath, and cut the rest along the cable axis, separate the three-phase core wires, and remove the filling The stripping and cutting operation should ensure that the copper shielding is intact and the core wire must not be damaged;

[0028] b. Peel off the copper shielding layer, measure 180mm upwards at the incision of the outer sheath at the end of the cable, wrap the copper shielding tape tightly with a self-adhesive PVC tape, and cut the copper shielding axis with a knife. Pay attention to the depth and not to cut the semiconductor Layers, neat ports, no burrs;

[0029] c Phase color mark, distinguis...

Abstract

The invention discloses a method for manufacturing a high-voltage power cable terminal by a benzene hydrogenation process. The method is characterized by comprising the following steps of: a, stripping and cutting a cable; b, stripping a copper shielding layer; c, making gas chromatographic marks; d, stripping a semiconductor; e, cutting an anti-stress cone of each phase of an insulating layer of a core; f, crimping a terminal; g, removing the insulting layer; h, arranging an insulating tube; i, fixing the insulating tube and a gas chromatographic tube; and j, performing enveloping processing. The method for manufacturing the high-voltage power cable terminal by the benzene hydrogenation process has the advantages of rational manufacturing steps, simple operations, safe and reliable process quality, high electrical properties and reduction in process cost.

Description

technical field [0001] The invention relates to a method for manufacturing a cable terminal for electrical equipment, in particular to a method for manufacturing a high-voltage power cable terminal for a benzene hydrogenation project. Background technique [0002] The process of benzene hydrogenation unit is quite special, its system is complicated, there are many equipments, the pressure and temperature of the system itself are high, and the pump equipment is not allowed to run idle. The benzene hydrogenation project is mainly divided into the central control room and substation, refining device, water supply and drainage project, air compressor station, storage and transportation facilities (tank farm and pump room), power supply for the whole plant and lighting for the whole plant, torches and ancillary projects Facilities, in the electrical installation of these facilities, there are special requirements for lightning protection, fire protection, and explosion protection...
