Technical Field

The utility model relates to the technical field of cables, concretely relates to novel cables.

Background

The cable, usually several or several groups of wires (each group is at least two) twisted into the cable similar to the rope, each group of wires are insulated from each other and usually twisted around centers, the whole outside is wrapped with a highly insulating covering layer, the cable has the characteristics of internal power supply and external insulation, the manufacturing mode of the cable is completely different from the production mode of most electromechanical products, the electromechanical products are usually manufactured by assembling parts and assembling a plurality of parts into a single product, and the products are measured by the number of the parts or the number of the parts.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that novel cables are provided, it has the radiating effect good, advantage that anti-seismic performance is strong.

novel cables comprise a support framework with a hollow structure, wherein 6 heat insulation interlayers are uniformly arranged on the outer side wall of the support framework along the circumferential direction, a cable core is arranged between every two adjacent heat insulation interlayers, a fire protection layer which is sealed in a surrounding mode is arranged at the end, far away from the support framework , of each 6 heat insulation interlayers, a buffer layer is filled between the support framework and the fire protection layer, the outer periphery of the fire protection layer is wrapped with a protection layer, and heat dissipation holes communicated with the buffer layer are formed in the fire protection layer and the protection layer.

Preferably, an insulating layer is arranged on the outer wall of the cable core. The cable core is prevented from being in direct contact with the outside, and the protection effect is achieved.

preferably, the insulating layer is covered with a waterproof layer on the outer side wall, which effectively prevents the insulating layer from aging caused by the contact of water with the insulating layer.

Preferably, the supporting framework is a hard heat insulation silica gel layer. The stability of the internal structure of the cable is ensured.

Preferably, the insulating barrier is a layer of glass fibre material. The insulativity of the cable is enhanced, the glass fiber has stronger heat resistance and corrosion resistance, and the service life of the cable is effectively prolonged.

Preferably, the buffer layer is a soft honeycomb insulating rubber layer. Enhancing the flexibility and processability of the cable.

Has the advantages that: the utility model discloses support chassis guarantees the stability of cable inner structure, and adiabatic interlayer is separated the cable core and is made the produced heat of cable conductor transmit to along the louvre, the outside of flame retardant coating and protective layer, and the shock resistance of cable can be strengthened to the buffer layer for the cable can adapt to more abominable application environment.
