Problems solved by technology

[0002] In the actual production and use of cables, the actual number of meters of a cable produced by an enterprise cannot be infinitely long. During the laying process, there are cable bruises that cause segmentation, so cable intermediate joints are required. Currently, cable intermediate joints are produced. The cost is relatively high, resulting in the construction party making intermediate joints easily and unsafe to use

Embodiment Construction

[0012] The invention provides a low-voltage cable intermediate joint method, comprising the following steps:

[0013] 1) Put the heat-shrinkable plastic cable on the cable on either side, and overlap the cable on the other side. The core of the cable, including the conductor, is crimped with a conductor sleeve. The size of the conductor sleeve is the same as the nominal cross-section of the cable;

[0014] 2) Three layers of refractory mica tape are overlapped and wound outside the cable sheath, and the insulation material of the same material is used for radiation cross-linked heat shrinkable film, and the thickness of the winding insulation is 1.1-1.2 times the nominal thickness;

[0015] 3) Heat the radiation cross-linked heat-shrinkable film to shape the radiation-cross-linked heat-shrinkable film, tightly wrap the conductor, and then wrap it with a layer of waterproof tape.

[0016] The cable lapping process described in step 1) is as follows: first lap the wire cores, an...

Abstract

The invention provides a low-voltage cable intermediate connector manufacturing method. A thermal contraction type plastic cable sleeve is arranged on a cable on any one edge in a penetrating manner to be lap jointed with the cable on the other edge; the cable core of the cable comprises a conductor which is crimped by adopting a conductive sleeve; next, the exterior of the cable sleeve is overlaid and wound with three layers of fireproof mica bands; the same kind of insulating material is adopted for forming a radiation and crosslinking thermal contraction film; and finally, the radiation and crosslinking thermal contraction film is heated to form the radiation and crosslinking thermal contraction film. The low-voltage cable intermediate connector manufacturing method is low in cost, convenient to operate and high in safety.

Description

technical field [0001] The invention relates to the field of cables, in particular to a low-voltage cable intermediate joint method. Background technique [0002] In the actual production and use of cables, the actual number of meters of a cable produced by an enterprise cannot be infinitely long. During the laying process, there are cable bumps that lead to segmentation, so cable intermediate joints are required. Currently, cable intermediate joints are produced. The cost is relatively high, resulting in the construction party making intermediate joints easily and unsafe to use. Contents of the invention [0003] In order to solve the problems of the prior art, the present invention provides a low-cost, easy-to-operate low-voltage cable intermediate joint method with high safety. [0004] The present invention comprises the following steps: [0005] 1) Put the heat-shrinkable plastic cable on the cable on either side, and overlap the cable on the other side. The core of...
