Abstract
The utility model discloses an ultra-shielding signal cable resisting an electromagnetic pulse, and belongs to the technical field of cables. The ultra-shielding signal cable comprises a cable core, wherein at the outer side of the cable core, a first winding covering layer, an inner tinned copper wire woven mesh shielding layer, a ferro-nickel alloy belt magnetism conducting layer, an outer tinned copper wire woven mesh shielding layer and an outer sheath layer are arranged in sequence; the cable core comprises three strands of wire cores; each strand of wire core comprises four insulated conductor groups which are twisted with one another; a second taped covering layer is arranged at the outer side of the four insulated conductor groups which are twisted with one another in each strand of wire core; and each insulated conductor group comprises a copper conductor, and an insulating layer is wrapped at the outer side of each copper conductor. The ultra-shielding signal cable is simple and reasonable in structure, easy to produce and manufacture, low in cost, excellent in heat aging property, high in strength, good in abrasion resistance and fire resistance, cold-resistant, wide in applicable environmental conditions, and capable of satisfying the using requirements of electronic and electrical systems with specific requirements on resistance to strong electromagnetic fields with the electromagnetic pulse.
Description
Technical field
The utility model relates to the cable technology field, relates in particular to the serious or plateau thunder and lightning of the open-air electromagnetic interference communication cable technical field under the extreme weather conditions such as take place frequently.
Background technology
Along with external electromagnetic field constantly strengthens, the extensive use of the accurate control instrument of various high-tech, it is very important that electromagnetic compatibility just seems, is exactly because the Electro Magnetic Compatibility of cable is poor in many situations so that therefore system's generation misoperation proposes the very high requirement to the electromagnetic compatibility of cable.The screen of the various cables such as the control cables of at present China's production, computer cable, power cable generally adopts proof copper-wire braided shielding, the wrapped shielding of copper strips, the wrapped shielding of steel band, the wrapped shielding of aluminium strip, proof copper-wire braided to add 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, although shielding properties slightly is improved, but flexibility is poor, can only use in regulation and lay occasion.Because this class cables manufacturing technology is higher, shielding properties requires height, cable flexibility to require, and the shielding construction design difficulty is large.At present, also there are not to resist strong-electromagnetic field interference or strong electromagnetic pulse can satisfy again the super shielded type cable that soft requirement is conveniently laid.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, provides that a kind of electromagnetic pulse-resisting performance is good, flexibility is good, signal transmission performance is good, high strength, the super signal shielding cable of electromagnetic pulse-resisting that heat resistance is good.
The utility model comprises cable core, sets gradually the first lapping layer, interior tinned copper wire mesh grid screen, dilval band magnetic layer, outer tinned copper wire mesh grid screen and external sheath layer in the described cable core outside; Described cable core comprises the compenzine core, and per share core comprises respectively four mutual stranded insulated electric conductor groups, in the described per share mutual four stranded eradication edge conductor groups outsides the second lapping layer is set respectively; Described every eradication edge conductor group comprises respectively copper conductor, at described per share copper conductor outside difference wrap insulate layer.
Electrical insulation properties, excellent, the low-loss cross-linked polyolefin material of mechanical performance are adopted in the utility model insulation; Stranding adopts star quad stranding formula quad cabling unit, concentric-type cabling, and adopt wrapped the tightening of high-strength polyester band; That sheath adopts is cold-resistant, softness, high strength, high-wearing feature, coefficient of friction is low, anti-flammability is high inferior light polyurethane elastomer are material.
The utility model is simple and reasonable, manufacture easily, cost is low, cable has less insulation dielectric loss and good shielding properties, its shielding transfer impedance is not more than 1 Ω/m and has good heat aging performance in the 1000MHz scope, intensity is high, resistance to wear is good, good flame resistance, cold-resistant, the suitable environment condition is wide, can satisfy the electric system instructions for use that the electromagnetic pulse-resisting strong-electromagnetic field is had specific (special) requirements.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model comprises cable core, sets gradually the first lapping layer 1, interior tinned copper wire mesh grid screen 2, dilval band magnetic layer 3, outer tinned copper wire mesh grid screen 4 and external sheath layer 5 in the cable core outside; Cable core comprises compenzine core 6, and per share core 6 comprises respectively four mutual stranded insulated electric conductor groups 7, in per share mutual stranded four eradication edge conductor groups, 7 outsides the second lapping layer 8 is set respectively; Every eradication edge conductor group 7 comprises respectively copper conductor 9, at per share copper conductor 9 outsides difference wrap insulate layer 10.
