Embodiment Construction

[0013] The present invention is described in detail below in conjunction with accompanying drawing and specific embodiment:

[0014] figure 1 A high flame-retardant and fire-resistant power cable is shown, including an oxygen-insulating filling layer 4, which plays the role of oxygen-insulating and filling rounding. The oxygen-insulating filling layer 4 is provided with a plurality of conductors composed of multiple annealed copper wires. 1. The conductor 1 can also be a single conductor ， The oxygen barrier filling layer 4 is provided with a second fireproof layer 5, which plays the role of oxygen barrier and filling roundness. The second fireproof layer 5 is tightly wrapped with an armor layer 6, and the armor layer 6 is coated with Zinc steel strip (or non-magnetic steel strip or aluminum strip) plays the role of cable protection and fire prevention. The armor layer 6 is provided with a high flame-retardant low-smoke and halogen-free outer sheath 7 to protect the cable an...

Abstract

The invention relates to a high flame retardant fireproof power cable, which comprises an oxygen-barrier packing layer, wherein a plurality of conductors consisting of a plurality of soft copper wires are arranged in the oxygen-barrier packing layer; a second fireproof layer is arranged outside the oxygen-barrier packing layer; an armor layer is closely coated on the second fireproof layer; and a high flame retardant low smoke zero halogen sheath layer is arranged outside the armor layer. The invention has the advantages that when the high flame retardant fireproof power cable is manufactured, cables with different cores can be manufactured according to requirements of users, and a protective layer of the cable can be designed according to the laying environment of the users.

Description

technical field [0001] The invention proposes a high-rise building, an underground shopping mall and other occasions that require high fire performance, and particularly relates to a high flame-retardant and fire-resistant power cable. Background technique [0002] With the development of the economy and the continuous improvement of people's living standards, the building housing industry is booming all over the country, especially high-rise building housing has sprung up in large and medium-sized cities. High-rise residences, like other high-rise buildings and high-end hotels, have put forward more stringent operating conditions for the fire protection characteristics, safety and reliability of building wires and cables. Such as fireproof, explosion-proof, strong overload capacity, long service life, under fire conditions, fire elevators, fire pumps need to maintain normal operation for a certain period of time, after the cable is burned, it has low smoke, low halogen and...
