Problems solved by technology

[0002] Cable is an indispensable equipment in electric power operation. With the increase of domestic and industrial electricity consumption year by year, the amount and type of cables used are also increasing. In the prior art, the main line of cable laying needs To bury multiple cables together, the usual practice is to bind multiple cables together. The binding is not firm when binding, and it is easy to disperse after a period of use, and it is not easy to distinguish, which brings inconvenience to the later maintenance of the cables; in addition, The overall structural strength of the cable is insufficient. If the binding is too strong, it will easily cause deformation and bending of the cable, which will affect the transmission of signals.

Abstract

The invention discloses a cable convenient to branch for a trunk line. The cable comprises an outer sheath, wherein the outer sheath sleeves an external insulation layer, a tensile central core is arranged at a central position of the external insulation layer, four first support plates are arranged on the tensile central core in an annular array way, the four first support plates are arranged ina cross shape and are used for equally dividing the external insulation layer into four accommodating spaces, three wires are arranged in each accommodating space, a first arc plate is arranged at oneside of each first support plate, a second arc plate is arranged at the other side of the first support plate, a first tear strip is arranged at each first support plate, a second support plate is arranged at one end, far away from the first support plate, of the first arc plate, and a second tear strip is arranged at the second support plate. The cable has the beneficial effects that a pluralityof cables are integrally buried, no interference is generated among different types of cables, and the cable can be convenient to branch.
