A safe tensile cable

Abstract

A safe tensile cable includes an insulating sleeve. A hexagonal central tube is arranged at the center of the insulating sleeve, the six sides of the central tube are adjacent to cable ducts and wireducts, and the centers of the center tube, the cable ducts and the wire ducts are provided with through holes. An aluminum wire is arranged in the through hole of the central tube, copper wire strandsare arranged in the through holes of the cable ducts, and the through holes of the wire tube are provided with tension ropes; the space between the central tube, the cable ducts and the wire ducts and the insulating sleeve is provided with a buffer layer, the space among the cable ducts, the wire ducts and the insulating layer is provided with a heat insulating layer, a support layer is arrangedbetween the adjacent cable ducts and the wire ducts. The center tube and the cable ducts and the wire tducts adjacent to the center tube are arranged, the tensile strength of the cable is improved bythe tension rope, the cable can be tightly bound on the cylinder and the like by the aluminum wire, and the safety of the cable can be improved by the heat insulation layer, and the cable ducts are isolated by the wire ducts, thereby avoiding the mutual transfer of heat and the excessive temperature of the cable.

Description

technical field [0001] The invention relates to the electrical field, in particular to cables, in particular to a safe tensile cable. Background technique [0002] The existing cables have poor tensile resistance, and the cables will be deformed and torn under a certain tension, and in the existing cables, when bending or winding on certain structures such as columns, the copper wires in the cables are deformed There will be a certain reverse force in the future, so that the copper wire will gradually become loose after being wound on the cylinder, and will be separated from the cylinder, which will not play a good fixing role and will cause unsafe factors. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a safe tensile cable. [0004] The present invention is achieved in the following way: a safe tensile cable, comprising an insulating sheath, characterized in that: a hexagonal central tube is arranged at the ce...
