Problems solved by technology

[0002] For a long time, the conventional large-section cables selected for special occasions such as emergency power distribution systems, special operation ignition systems, electric drive vehicles and equipment power distribution systems have problems such as heavy weight, heavy winding and unwinding, etc., which are extremely inconvenient for practical application. And it is difficult to meet the requirements of low-smoke, halogen-free, flame-retardant, fire-resistant and low-toxicity. Therefore, under the above background conditions, a new type of low-smoke, halogen-free, flame-retardant, fire-resistant and high-current-carrying flexible cable is needed to meet the requirements of the development trend and ensure that the cable In the case of high current carrying, the heat generated by the current is quickly dissipated to ensure that the cable can continue to work reliably, and at the same time it can meet the requirements of low-smoke, zero-halogen, low-toxicity, flame-retardant and fire-resistant

Embodiment Construction

[0015] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0016] Such as figure 1 As shown, taking the rated voltage of 0.6 / 1kV and below the high-current-carrying flexible cable single-core cable as an example, a rapid heat dissipation high-current-carrying cable includes a conductor 1, and the conductor 1 is wrapped with an insulating layer 2, and the insulating layer 2 is provided with an alkali-free and wax-free glass fiber layer 3, and the alkali-free and wax-free glass fiber braided layer is provided with a coating layer.

[0017] The insulating layer 2 is a vulcanized silicone rubber insulating layer added with high thermal conductivity ceramic nanopowder, and the insulating layer 2 is a vulcanized silicone rubber insulating layer extruded by a kneading process. And in-line vulcanization and cross-linking.

[0018] The non-alkali and wax-free glass fiber layer 3 is a braided layer of non-al...

Abstract

The invention discloses a rapid heat dissipation large-current-carrying cable, and the cable comprises a conductor which is wrapped by an insulating layer. The insulating layer is wrapped by an alkali-free wax-free glass fiber layer, and the alkali-free wax-free glass fiber layer is wrapped by a coating layer. The cable is larger in current capacity than a common cable, can meet the requirements of a larger load, reduces the diameter of the cable, reduces the weight of the cable, has the low-smoke no-halogen and high-retardance performances, and is good in flexibility.

Description

technical field [0001] The invention relates to a cable, in particular to a rapid heat dissipation and high current-carrying cable. Background technique [0002] For a long time, the conventional large-section cables selected for special occasions such as emergency power distribution systems, special operation ignition systems, electric drive vehicles and equipment power distribution systems have problems such as heavy weight, heavy winding and unwinding, etc., which are extremely inconvenient for practical application. And it is difficult to meet the requirements of low-smoke, halogen-free, flame-retardant, fire-resistant and low-toxicity. Therefore, under the above background conditions, a new type of low-smoke, halogen-free, flame-retardant, fire-resistant and high-current-carrying flexible cable is needed to meet the requirements of the development trend and ensure that the cable In the case of high current carrying, the heat generated by the current is quickly dissipate...
