SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to overcome current defect, provide the integral type cable, fire prevention fire resistance is stronger, and crushing resistance is better, is difficult to damage, has prolonged the life of cable, can effectively solve the problem in the background art.

In order to achieve the above object, the utility model provides a following technical scheme: integral type cable, including the protection crust, protection crust internal surface is connected with first support protective sheath, a plurality of metal shrapnel, per two have evenly been laid to the internal surface of first support protective sheath the cavity intussuseption between the metal shrapnel is filled with fire-retardant filler, the end connection of metal shrapnel has the second to support the protective sheath, the internal surface that the second supported the protective sheath is connected with the metal supporting net, the internal surface of metal supporting net is connected with the flame retardant coating, the internal surface of flame retardant coating is connected with the shielding layer, the internal surface of shielding layer is connected with the inner liner, the inside of inner liner is equipped with a plurality of cable core, and is a plurality of cavity intussuseption between the cable core is filled with the resistance to compression filler.

As an optimized technical scheme of the utility model, metal shrapnel is in first support protective sheath with be in the arc stress state between the second support protective sheath.

As an optimized technical scheme of the utility model, the shielding layer with through the fixed bonding of viscose layer between the flame retardant coating.

As an optimized technical proposal of the utility model, the protective sheath is composed of a steel belt and a rubber sheath from inside to outside in sequence.

As an optimal technical scheme of the utility model, the cable protection endothelium is by interior and constitute with wrapping the band outward by the insulating layer in proper order.

Compared with the prior art, the beneficial effects of the utility model are that: metal shrapnel through setting up arc stress state is convenient for when protection crust and the burning of first support protective sheath, after protection crust and first support protective sheath are burnt out, will connect the protection crust and the bullet of first support protective sheath on this integral type cable through metal shrapnel and fall, and can make fire-retardant filler diffusion around this integral type cable, further prevent the burning of flame, avoid this integral type cable inside to receive the influence of burning, the fire prevention fire resistance is stronger, the security of this integral type cable has been improved, be convenient for improve the crushing resistance of this integral type cable through setting up the resistance to compression filler, be difficult to damage, the life of cable has been prolonged.
