Fireproof cable with high heat dissipation performance

Abstract

The invention provides a fireproof cable with high heat dissipation performance, and the cable comprises a cable core; the cable core is formed by twisting insulating wire cores, each insulating wire core comprises a conductor, an insulating layer is wrapped outside each conductor, a filling layer is arranged in a gap between a preset number of insulating wire cores, and the filling layer is arranged between the insulating wire cores; the fire extinguishing layer, the inner flame-retardant layer, the fireproof layer and the outer flame-retardant layer are arranged outside the filling layer, so the fireproof cable has the characteristics of good heat resistance, flame retardance, fire prevention and fire extinguishing, multiple protection is performed on the cable core, and the conductors in the cable core are prevented from being burnt out. Meanwhile, a preset number of inner heat dissipation holes are formed in the circumference of the fireproof layer at intervals and penetrate through the fireproof layer, a preset number of outer heat dissipation holes sequentially penetrate through the outer flame-retardant layer and the outer sheath and are formed in the circumference of the outer flame-retardant layer and the outer sheath at intervals, heat in the cable is dissipated through the inner heat dissipation holes firstly, and then heat in the cable is dissipated through the outer heat dissipation holes. Meanwhile, heat is further diffused outwards through the outer heat dissipation holes, so the heat dissipation performance of the fireproof cable is improved, and potential safety hazards are reduced.

Description

technical field [0001] The invention relates to the technical field of wires and cables, in particular to a fireproof cable with high heat dissipation performance. Background technique [0002] In recent years, in order to improve the safety level of electrical lines and reduce the occurrence and loss of electrical fire accidents, the Ministry of Construction, the Ministry of Public Security and some local governments have successively issued some electrical design specifications, and clearly stipulated that in some important electrical lines and places Fireproof cables with high heat dissipation performance must be used, which further broadens the application range of fireproof cables with high heat dissipation performance. [0003] The existing ordinary fireproof cables only have one layer of fireproof insulating layer, so the fireproof efficiency is limited. Moreover, ordinary fire-resistant cables will generate a certain amount of heat when used for a long time. Since t...

Problems solved by technology

The present invention can effectively prevent further wear of the cable during the dragging process by allowing the high-hardness and wear-resistant nano-inorganic ceramic resin to form rings at intervals on the outside of the cable. The process is simpler and will not affect the bending and winding of the cable, but its fire performance is poor and it does not include the setting of the heat dissipation module, resulting in excessive temperature
