Embodiment Construction

[0034] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0035] figure 1 A structural schematic diagram of cable stripping of the present invention is given.

[0036] This embodiment provides a method for manufacturing a 10kV heat-shrinkable three-core XLPE cable intermediate joint, including the following steps:

[0037] S1: Align and cut the cables. After removing the metal stress of the two cables for the intermediate joint, align the two cables and overlap them by 200-300mm. Determine the center of the intermediate joint and align the core wires of the cables. cut the two cables;

[0038] S2: Strip the outer sheath layer and armor, take the size of the outer sheath layer according to the specific demand, and strip the outer sheath layer to expose the armor....

Abstract

The invention relates to a method for making a 10KV heat-shrinkable three-core cross-linked polyethylene cable intermediate joint, comprising the following steps: S1, aligning and cutting a cable; S2, stripping an outer sheath layer and an armor; S3, stripping an inner sheath layer and a filler layer; S4, stripping a copper shielding layer and an outer semi-conducting layer; S5, fixing a stress pipe; S6, sleeving pipes; S7, crimping a connecting pipe; S8, wrapping a semi-conducting band; S9, wrapping a filling adhesive tape, S10, fixing a composite pipe; S11, wrapping a waterproof adhesive tape; S12, wrapping a semi-conductive band; S13, installing a three-edged conductive wedge rod; S14, installing a copper shielding net and a ground line; and S15, fixing sealed sheath pipes. For an intermediate joint prepared by the method, the occurrence of tiny cracks or holes is avoided effectively, and the safety factor is improved greatly.

Description

technical field [0001] The invention belongs to the field of production technology of power cable joints, and relates to a production process of cable intermediate joints, in particular to a production method of 10kV heat-shrinkable three-core XLPE cable intermediate joints; the intermediate joints produced by the method are effective Avoid the generation of tiny gaps and holes, fully reduce the possibility of water seepage in the intermediate joints, and significantly improve the safety performance. Background technique [0002] Power cables are an indispensable element in the power supply system. The safety performance of power cables is not only related to the normal operation of electrical equipment, but also crucial to the safety of workers. [0003] The power cables of the power supply system may be damaged by various external factors (such as mechanical force, etc.), resulting in an inevitable increase in the use of cable intermediate joints. Due to the professional ...
