Embodiment 1

[0017] A cable gland method, comprising the following steps:

[0018] 1) Cut the end of the cable flat;

[0019] 2) Immerse the flattened end into the heated and melted asphalt for 5 minutes so that the asphalt penetrates into the inner gap of the cable;

[0020] 3) Pull out the cable and put on the cable head cap;

[0021] 4) Heat the head cap to shrink and seal the cable;

[0022] 5. Immerse the cable end in cold water for 1 minute to make the asphalt solidify and complete the head.

Embodiment 2

[0024] A cable gland method, comprising the following steps:

[0025] 1) Cut the end of the cable flat;

[0026] 2) Immerse the flattened end into the heated and melted asphalt for 7 minutes so that the asphalt penetrates into the inner gap of the cable;

[0027] 3) Pull out the cable and put on the cable head cap;

[0028] 4) Heat the head cap to shrink and seal the cable;

[0029] 5. Immerse the cable end in cold water for 1.5 minutes to make the asphalt solidify and complete the head.

Embodiment 3

[0031] A cable gland method, comprising the following steps:

[0032] 1) Cut the end of the cable flat;

[0033] 2) Immerse the flattened end into the heated and melted asphalt for 10 minutes so that the asphalt penetrates into the inner gap of the cable;

[0034] 3) Pull out the cable and put on the cable head cap;

[0035] 4) Heat the head cap to shrink and seal the cable;

[0036] 5. Immerse the cable end in cold water for 2 minutes to make the asphalt solidify and complete the head.

Abstract

The invention relates to a sealing end method comprising the following steps: 1) cutting flat the cable ends; 2) immerging the cut ends into the heating molten asphalt and holding for a certain time; 3) taking out the cable and covering a cable sealing cap; 4) heating the sealing cap to shrink and seal the cable; 5) cooling the sealing parts and completing head plate. The sealing end method of the invention has advantages of convenient drawing materials, easy operation, low cost and good sealing effect.

Description

technical field [0001] The invention belongs to the field of electric wires and cables, and in particular relates to a cable sealing method. Background technique [0002] The cable is usually sealed with a head cap after the finished product. The size of different cables and head caps during production will definitely be slightly different, which causes the head cap to have poor sealing performance and easy to fall off. The material of the head cap also has shortcomings such as easy rupture, poor durability, and easy aging. Therefore, in the medium and high voltage cables with high waterproof requirements, it is very important to prevent moisture before the cable is installed and used, so the use of head caps is not particularly suitable. . SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is to provide a cable sealing head method to solve the defect that the sealing is not strict and easy to fall off in the prior art.
