Description

A smart energy-saving cable

technical field

The utility model relates to a cable, in particular to a smart energy-saving cable.

Background technique

In the actual application of cables, round cables or fan-shaped cables are basically used. Circular power cables ranging from single core to five cores have circular inner cores and cables, and the material waste of circular cables is relatively large, which does not meet the current requirements for energy saving and consumption reduction; fan-shaped cables have small material loss for symmetrical shapes. But for cables with three big ones and one small one, three big ones and two small ones, the advantages of energy saving and consumption reduction cannot be reflected, and materials are also wasted.

Utility model content

The purpose of the utility model is to reduce the material cost of the three-phase five-wire cable, make the cable structure compact, and provide a cable with less material usage and simple structure, which can be realized on general equipment.

The technical solution to realize the purpose of the utility model is a smart energy-saving cable, which consists of a cable core, a tape, a neutral wire and an outer sheath from the inside to the outside; the cable core includes three power cores and one ground core ; The ground wire core is a round wire, located in the center of the cable core; the three power wire cores are equally divided tile-shaped structures, which are closely attached to the outside of the ground wire core; the neutral wire is a bare copper wire.

The power core includes a power core stranded conductor and a power core insulating layer covering the outside of the power core stranded conductor.

The ground core includes a ground core stranded conductor and a ground core insulating layer covering the outside of the ground core stranded conductor.

The neutral wire adopts a structure in which several bare copper wires are wound outside the tape.

Both the insulating layer of the power core and the insulating layer of the ground core are insulated by cross-linked polyethylene or cross-linked polyolefin or polyethylene or polyvinyl chloride; the outer sheath is polyvinyl chloride or polyethylene or low-smoke halogen-free Flame retardant polyolefin.

Adopting the above-mentioned technical scheme, the utility model has the following beneficial effects: (1) The power cable core of the utility model adopts a tile-shaped structure, which can reduce the use of filler materials; the zero line is wound outside the cable core, reducing the outer diameter of the cable, Reduce jacket material usage. The combination of circular ground wire and tile-shaped power wire has a compact and round structure.

(2) The structure design of the utility model is reasonable, conventional equipment and conventional technology can be adopted, the conventional three-phase five-wire cable structure is optimized, the use of insulation, filling and sheath materials is reduced, the cost of cables is reduced, and the market competition of products is improved force.
