Description

A kind of shield cable

Technical field

The utility model relates to a kind of cable, is specifically related to a kind of shielded type cable.

Background technology

Along with the fast development of national economy, as the aortal electric wire of national economy, its consumption and the scope of application are increasing.In recent years, the industries such as power plant, transformer station, smelting and petrochemical industry, very big to the demand of cable.

Generally speaking, electromagnetic shielded cable structure from the inside to the outside is followed successively by core, the insulating medium layer that is coated on the cable core outer surface, screen and the oversheath that forms inner wire.Wherein, cable core is used for transmission of electric signals, and material is take copper or ormolu as main.Screen is generally layer of metal foil, disturbs in order to shield electromagnetic interference or useless external signal.This type of screen well below the speed of production of cable system core, is the principal element of restriction electromagnetic shielded cable volume production on speed of production.

In sum, necessaryly provide a kind of insulation shielding effective, intensity is high, can adapt to all-environment electromagnetic shielded cable.

Summary of the invention

Goal of the invention: the purpose of this utility model is in order to overcome deficiency of the prior art, to provide a kind of shield effectiveness good, and integral product intensity is higher, adapts to all-environment shield cable.

Technical scheme: in order to solve the problems of the technologies described above, a kind of shield cable described in the utility model, it comprises two conductors, all is provided with insulating barrier outside every conductor, and its thickness is 2mm, on described insulating barrier, all be provided with the identification band, outside described insulating barrier, be provided with load bearing core, be provided with packed layer at described insulating barrier and load bearing core outside, outside described packed layer, be provided with lapping layer, outside described lapping layer, be provided with screen, outside described screen, be provided with external sheath layer.

Described conductor is copper conductor or tinned copper conductor.

Described screen is semiconductive conductor screen material screen.

Described packed layer is the composite material of silicon carbide packed layer.

Described lapping layer is polyester belt lapping layer or nonwoven layer.

Described external sheath layer is halogen-free and low-smoke flame-retardant polyolefin sheathed layer.

Beneficial effect: the utility model compared with prior art, its remarkable advantage is: screen of the present utility model adopts semiconductive conductor screen material screen, greatly improved shield effectiveness, add load bearing core, greatly improved the intensity of product, improved useful life simultaneously, and can be applicable to various occasions.
