Description

Branch-able waterproof cable

Technical Field

The utility model belongs to the technical field of the cable technique and specifically relates to a waterproof cable that can divide branch is related to.

Background

A cable is a conductor made of one or more conductors insulated from each other and an outer insulating sheath that carries power or information from one location to another. The cable may be classified into a power cable, a communication cable, a control cable, and the like according to its use. Compared with an overhead line, the cable has the advantages of small insulating distance between lines, small occupied space, no occupation of space above the ground due to underground laying, no influence of pollution of the surrounding environment, high power transmission reliability, and small interference on personal safety and the surrounding environment. But the cost is high, the construction and the maintenance are troublesome, and the manufacture is complicated. Therefore, the cable is mostly applied to dense areas of population and power grids and places with heavy traffic; when the cable is laid in the river, the river and the seabed, the use of large-span overhead lines can be avoided. Cables may also be used where it is desirable to avoid interference of overhead lines with communications and where aesthetic considerations or exposure to objects are desired. Since the cable is used externally for a long time, the surface of the cable is very easily damaged, thereby causing a water leakage phenomenon. In addition, in the laying process of cable, when needs are branched, often install cable joint in the junction, and present cable laying is mostly installed in the open air, and the cable joint who uses is mostly the disconnect-type, and the structure is more complicated, and the opening is more to there is the gap joint of joint and cable, and the rainwater gets into in the gap from the gap easily. The water leakage phenomenon of the cable not only can reduce the service life of the cable, but also has potential safety hazards, so that the cable capable of effectively preventing water is very necessary.
