Technical Field

The utility model relates to a cable field, concretely relates to waterproof and anti-aging's integral type power cable.

Background

With the development of society, cables are spread in various industries, information tends to be automated at present, information transmission and energy transportation are carried out through the cables, the cables are electric energy or signal transmission devices, generally, the cables are made of several or several groups of wires, one or more mutually insulated conductors and an outer insulating protection layer, the wires for transmitting electric power or information from one place to another place are generally stranded cables similar to ropes formed by several or several groups of wires, each group of wires are mutually insulated and are usually twisted around a center, the whole outer surface is wrapped by a highly insulating covering layer, and the cables have the characteristics of internal electrification and external insulation.

Most of the existing cables are composed of sheaths and cable cores, the cables are protected through different functions of the sheaths, energy and information are effectively transmitted, people's life is facilitated, and the information era is realized.

The existing cable is composed of a cable core and a protective sleeve, but the cable is buried in an underground humid environment and is easy to age, and the service life of the cable is influenced.

SUMMERY OF THE UTILITY MODEL

The utility model provides a waterproof and anti-aging's integral type power cable has solved the cable and has buried in the moist environment in underground, and is ageing easily, influences life's problem.

The technical scheme of the utility model is realized like this:

a waterproof and anti-aging integrated power cable comprises an inner core layer and an outer protective layer wrapped on the outer wall of the inner core layer;

the inner core layer comprises an inner protective layer with a circular section, the inner protective layer is made of ethylene propylene rubber materials, four inner core grooves are formed in the inner protective layer, an inner core assembly is arranged in each inner core groove, and each inner core assembly is formed by twisting a plurality of copper wires;

the outer protective layer comprises a flexible protective layer wrapped on the outer wall of the inner protective layer, an aluminum jacket metal layer sleeved on the flexible protective layer, and a plastic combined layer wrapped outside the aluminum jacket metal layer.

Preferably, the plastic composite layer comprises a rubber layer wrapped outside the aluminum jacket metal layer, a filling material layer wrapped outside the rubber layer, and a rigid polyurethane layer wrapped outside the filling material layer.

Preferably, the thickness of the aluminum clad metal layer is between 0.1 and 0.15 mm.

Preferably, the rubber layer is made of high-density polyethylene resin with water absorption rate less than 0.5%.

Preferably, the cross-sectional dimension of four of the inner core grooves is between 5 and 7 mm.

The utility model has the advantages that,

the utility model comprises an inner core layer and an outer protective layer wrapped on the outer wall of the inner core layer; the inner core layer comprises an inner protective layer with a circular section, the inner protective layer is made of ethylene propylene rubber materials, four inner core grooves are formed in the inner protective layer, an inner core assembly is arranged in each inner core groove, and each inner core assembly is formed by stranding a plurality of copper wires; the outer protective layer comprises a flexible protective layer wrapped on the outer wall of the inner protective layer, an aluminum jacket metal layer sleeved on the flexible protective layer, and a plastic combined layer wrapped outside the aluminum jacket metal layer. The inner protective layer made of ethylene propylene rubber is waterproof, so that an inner core assembly inside the inner core assembly is prevented from being affected with damp; and set up the aluminium sheathing metal level, increase waterproof dynamics to aluminium metal level has increased the outer protection of inner core subassembly, avoids ageing, has strengthened life greatly.
