Abstract
The utility model relates to a flexible electromagnetic pulse-resisting super-shielded cable. A layer of non-woven cloth belt or aluminum-plastic film compound belt protective layer is coated on the outer layer of a protective cable; two layers of metal conducting layers are coated outside the protective layer; a layer of magnetic conducting layer is arranged between the two layers of metal conducting layers. Through the test that the core electromagnetic pulse field strength is 50kV/m and the spectral range is less than 100MHz, the shielding performance of the utility model relates to 70dB. The flexible electromagnetic pulse-resisting super-shielded cable has good shielding performance and flexibility and convenient layout, and is especially suitable for the occasions of thunder, lightning and strong electromagnetic interference.
Description
The utility model relates to the super shielded type cable of a kind of electromagnetic pulse-resisting, the super shielded type cable of particularly a kind of soft type electromagnetic pulse-resisting.
The control cable of China's production at present, computer cable, the screen of various cables such as power cable generally adopts the shielding of individual layer copper mesh, the wrapped shielding of copper strips, the wrapped shielding of steel band, the wrapped shielding of aluminium strip, copper mesh adds the wrapped shielding of copper strips etc., the shielding properties of this type shielding cable can only resist the general interference of electromagnetic field, and shield with aluminum pipe or copper pipe, though shielding properties slightly improves, but its flexibility is poor, not flexible, can only use and fixedly lay occasion, at present, also there are not to resist strong-electromagnetic field interference or anti-strong electromagnetic pulse to satisfy the shielded type cable that soft requirement is conveniently laid again.
The purpose of this utility model is to provide the super shielded type cable of the good anti-strong electromagnetic pulse of a kind of softness.
The purpose of this utility model is to realize with following proposal: the super shielded type cable of a kind of electromagnetic pulse-resisting comprises and is followed successively by protected cable, protective layer, metal conducting layer, restrictive coating from the inner to the outer; metal conducting layer has two-layer, and is a floor height mu-metal band magnetic layer between the double layer of metal conductive layer.Protective layer can be that nonwoven fabric belts or aluminium plastic membrane composite band are wrapped on protected cable.The double layer of metal conductive layer is preferably copper wire mesh grid or tinned copper wire mesh grid or silver-gilt copper wire mesh grid.Sheath can be rubber or plastic sheath.
The utility model is simple in structure, is 50KV/m by the nuclear electromagnetic pulse field intensity, and spectral range is less than the test of 100MHZ, its shielding properties is about 70dB, and it has good shielding properties and softness, conveniently lays, be specially adapted to thunder and lightning, the occasion of strong electromagnetic.
Accompanying drawing has provided an embodiment of the present utility model.
Fig. 1 is the utility model cross sectional representation.
With reference to the accompanying drawings the utility model is described in further detail.
With reference to Fig. 1; the utility model shielded type cable innermost layer is protected cable 1; it can be computer cable, control cable, power cable etc.; skin at protected cable 1 is the wrapped protective layer of nonwoven fabric belts 2; coating two layers of copper wire mesh grid 3,5 and make conductive metal layer outside protective layer 2, is a floor height mu-metal band magnetic layer 4 between the two conductive metal layer, and this magnetic layer 4 is dilval bands; sheath 6 is coated in the copper wire mesh grid 5, is rubber or plastic sheath.
