Abstract

The utility model relates to a control cable, in particular to a copper-clad aluminum core silicon rubber insulating and sheathing power cable which belongs to the field of electric wires and cables. The copper-clad aluminum core silicon rubber insulating and sheathing power cable mainly comprises a plurality of wire cores, a belting layer, a shielding layer and a sheath; each wire core consists of a conductor and an insulating layer which is arranged outside the conductor; the belting layer is arranged outside a single wire core; the shielding layer is arranged outside the belting layer; the sheath is arranged outside the shielding layer; the conductor is made of a copper-clad aluminum wire; the insulating layer is made of silicon rubber; the sheath is made of silicon rubber; and the belting layer is a non-moisture absorption insulating belt. The copper-clad aluminum is mainly made of copper, thereby not only overcoming the shortcomings that a pure copper conductor has large density and high cost and is difficult to move but also solving the defects that the pure aluminum has low conductivity and weak welding performance, the surface can be oxidized easily are solved, etc; furthermore, the insulation design is more advanced and reliable. The copper-clad aluminum core silicon rubber insulating and sheathing power cable has good market prospect due to excellent cost performance and wide applicability and durability.

Description

Copper-covered aluminum-core silicon rubber insulation and sheath power cable

Technical field

The utility model relates to control cable, relates in particular to copper-covered aluminum-core silicon rubber insulation and sheath power cable, and it belongs to the electric wire field.

Background technology

At present, the electric wire that uses on the market generally adopts the fine copper conductor wire core of conductor as multicore or single core softness, and insulating barrier mostly is SE4 type neoprene, polyvinyl chloride or other suitable synthetic elastomer composite materials, and cover layer constitutes the double sheath of insulation.The density of well-known pure cu conductor is big, and the cost height is difficult for moving; The cost of copper accounts for 60 ~ 70% of finished product, and market competition is fierce unusually, and most of enterprise adopts does little silk and use inferior materials and turn out substandard goods and reduce the cost, the quality that causes electric wire, and present domestic copper material market is very well sold and in short supply, and price is high high, a kind of energy-saving product that can replace copper wire of market in urgent need.

Summary of the invention

In order to solve the problem that above-mentioned prior art exists, the utility model provides copper-covered aluminum-core silicon rubber insulation and sheath power cable, and it adopts copper-covered aluminum-core is conductor, has reduced the cost of cable itself.

The technical scheme that its technical problem that solves the utility model adopts is: copper-covered aluminum-core silicon rubber insulation and sheath power cable, it mainly comprises several wire core, belting layer, screen and sheath, core is made up of conductor and the outer insulating barrier of conductor, the outside of described single core is provided with belting layer, the belting layer outside is provided with screen, the screen outside is provided with sheath, described conductor adopts copper-clad aluminum conductor, described insulating layer material is a silastic material, described sheath material is a silicon rubber, and described belting layer is non-moisture absorption row insulating tape.

It is core that copper-covered aluminum-core silicon rubber insulation that provides of the present utility model and sheath power cable adopt copper-clad aluminum conductor, copper cover aluminum is to be main material with copper, and the density that it has not only overcome pure cu conductor is big, the cost height, be difficult for mobile shortcoming, simultaneously also avoided the conductivity of fine aluminium low, welding performance is poor, defectives such as the easy oxidation in surface, and insulating Design is advanced more, reliable, the cost performance that it is good, extensive applicability and durability make its market prospects extremely good.
