Embodiment 1

[0025] A method for plugging the end of a cable bushing involved in this embodiment, the specific process steps are:

[0026] (1) At the outlet of the cable casing, use air bags or cloth bags 4 filled with cement to fix multiple cables 1 together and fix them in the middle of the inner cavity port of the cable casing 2, and then attach each cable 1 to the Together, the cable 1 cannot move freely;

[0027] (2) Take the polymer resin waterproof and anti-corrosion coating and mix it evenly, and apply the polymer resin waterproof and anti-corrosion coating on the surface layer between multiple cables 1 that need to be fixed. The cable 1 fixed position is far from the port of the cable sleeve 2 2-5 cm, so that the gap between the fixing points of multiple cables 1 is tightly sealed by polymer resin waterproof and anti-corrosion coating;

[0028] (3) Add the polymer resin waterproof and anti-corrosion coating evenly into the 2 port of the cable sleeve. Due to the existence of air b...

Embodiment 2

[0040] This embodiment relates to a kind of cement mortar used for preparing the plugging layer 3. When the cement mortar is used for plugging the cable sleeve 2, cement, fine sand and fine hemp silk with a length of 2-3 cm are pressed by 1 : Mix at a weight ratio of 1:0.05, then add water in a conventional weight mixing ratio, mix uniformly to obtain cement mortar, then carry out plugging operation according to Example 1, and prepare plugging layer 3.

Abstract

The invention belongs to the technical field of cable pipe mouth sealing, and relates to a method for sealing the end of a cable sleeve; In the middle part, (2) apply the polymer resin waterproof and anti-corrosion coating between multiple cables, so that the gaps between the multiple cables are sealed tightly, (3) evenly add the polymer resin waterproof and anti-corrosion coating to the cable sleeve In the pipe port, (4) compact and smooth the polymer resin waterproof and anti-corrosion coating in the cable sleeve port, and form a sealing layer after curing. The gap between the wire and the cable casing is completely closed; the method is reasonable and complete, scientific and practical, the cable casing port is sealed and sealed, the sealing durability is strong, and the water resistance and fire resistance are excellent, which can effectively prevent water and dirt from entering the cable casing , effectively prolonging the service life of the cable.

Description

technical field [0001] The invention belongs to the technical field of cable nozzle plugging, and relates to a protection process for plugging the end of a casing for cable protection and preventing water from entering the inner cavity of the casing, in particular to a method for plugging the end of a cable casing. The method can seal and airtight the end of the cable casing, and has good protection for the cables in the casing. Background technique [0002] Cable sleeves, also known as protective tubes and conduits, are pipes used to protect wires and cable wiring in electrical installations, allowing wires and cables to penetrate and replace. Cable sleeves are a new type of sleeve that is popularized and used in electric power engineering Material; when the cable protrudes from the cable sleeve port and is associated with the equipment, the cable sleeve port is sealed with glue, oil paper, and adhesive tape to prevent dirt, water, etc. from entering the cable sleeve; but t...
