Communication cable (English name：Communication cable) refer to height for low coverage voice communication and long distance
Frequency carrier wave and digital communication and the cable of signal transmission, it is one of Chinese five big cable products.According to the purposes of communication cable and
Use range, can be divided into six big series of products, i.e. city communication cable (including paper insulation city words cable, polyolefin insulation polyene
Hydrocarbon sheath city talk about cable), long distance symmetric cable (including paper insulation low-and high-frequency long distance symmetric cable, copper core foamed polyethylene height
Frequency long distance symmetric cable and Digital Transmission long distance symmetric cable), coaxial cable (including small diameter coaxial cable, in it is coaxial and small
Coaxial cable), submarine cable (symmetrical seabed and coaxial submarine cable can be divided), fiber optic cables (including traditional cable-type, banding
Three kinds of array type and matrix type), radio-frequency cable (including symmetric radio frequency and coaxial radio-frequency).
China is vast in territory, and the north and south temperature difference is big, especially in the winter time, reachable -50 DEG C of the outdoor temperature of northeast some areas.
Under the conditions of arctic weather, plastics and partial rubber meeting are brittle, ftracture, or even the phenomenon of self falling occurs.Common electricity
Cable structure is simple, is adapted to construct in severe cold area, and compression strength is inadequate, is easily damaged, and particularly some are laid on road surface one
Under communication cable exist and be stressed larger, be easily pressed down, influence normal use.
Utility model content
Prior art is difficult to the needs for meeting people, and in order to solve above-mentioned problem, the utility model proposes one
Kind multi-functional communications cable.
To achieve the above object, the utility model provides following technical scheme：A kind of multi-functional communications cable, including fluorine rubber
Glue oversheath, waterproof layer, Withstand voltage layer, heat-insulation layer and metal wire, the fluorubber oversheath is internally provided with waterproof layer, described anti-
