Description
Technical field
The utility model belongs to electric cable accessories technical field, is specifically related to a kind of fireproof cable coupling assembling.
Background technology
Cable normally forms by several or several groups of wires (often organizing at least two) are stranded around center, the similar rope of its shape, simultaneously outer cover height insulating barrier.Cable has power cable, control cables, compensating cable, shielded type cable, high-temperature cable, aluminium alloy cable etc., and they are all made up of sub-thread or stranded conductor and insulating barrier, is used for connecting circuit, electrical equipment etc.
Along with China's expanding economy, various architectural engineering is with unprecedented scale and speed development, also more and more higher to the requirement of electric equipment.In recent years, because the fire electrically caused increases gradually, and the fire wherein caused due to electric wire reason occupies sizable ratio.
In order to complete long distance delivery electric energy, need two adjacent cable joints to connect, and joint is also link the weakest in transmission line, often be in the running environment of humidity, heavily contaminated, very easily there is breakdown accident, and cause fire, cause potential safety hazard.
Utility model content
In order to solve the problem, the utility model provides a kind of fireproof cable coupling assembling, improves the fire resistance at cable joint place, avoids the generation causing fire incident because of external environment impact.
A kind of fireproof cable coupling assembling, comprise two single-core cables connected and with the joint for being connected described single-core cable, described single-core cable is provided with core, insulating barrier, copper shield, semi-conductive layer, inner sheath and oversheath from inside to outside successively, the semi-conductive layer of described joint both sides is enclosed with the first adhesive waterproof tape, described joint both sides and described first adhesive waterproof tape are close to, and comprise fire-resistant isinglass belt in the base material of described first adhesive waterproof tape.
The utility model wraps up the first adhesive waterproof tape on the semi-conductive layer of joint both sides, can play waterproof action, and includes fire-resistant isinglass belt in the base material of adhesive waterproof tape of the present utility model, therefore can play fireproof effect simultaneously.
Described first adhesive waterproof tape and described joint are enclosed with copper mesh layers, and described copper mesh layers two ends are fixedly connected with described copper shield by constant force spring.
In order to better play the effect of waterproof fireproofing, as preferably, the inner sheath at described copper mesh layers and described copper mesh layers two ends being enclosed with the second adhesive waterproof tape, in the base material of described second adhesive waterproof tape, comprising fire-resistant isinglass belt.
In order to increase the mechanical strength of cable, improving erosion prevention, as preferably, between described inner sheath and described oversheath, being provided with armour.
Described second adhesive waterproof tape is wound with copper litz wire, and described copper litz wire two ends are fixedly connected with described armour by constant force spring.
As preferably, the oversheath at described copper litz wire and described copper litz wire two ends is enclosed with the 3rd adhesive waterproof tape, in the base material of described 3rd adhesive waterproof tape, comprises fire-resistant isinglass belt.
The form of joint has multiple, such as pyrocondensation joint and shrinkage joint, and wherein shrinkage joint volume is little, easy to operate, and as preferably, described joint is shrinkage joint.
Compared with prior art, the beneficial effects of the utility model are embodied in:
Of the present utility modelly be provided with adhesive waterproof tape in joint, and adhesive waterproof tape is provided with fire-resistant isinglass belt, therefore not only play waterproof action, can also fireproofing function be played, improve the fire resistance at cable joint place, avoid the generation causing fire incident because of external environment impact.
