Detailed Description
In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following detailed description will be given with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1, the embodiment of the utility model provides a be used for joining in marriage anti-interference high fire-retardant power cable of motor room pliability crosslinking, include the conductor 1 that forms by the transposition of annealing copper wire, the insulating layer 2 that has pliability crosslinking polyvinyl chloride insulating material to make is crowded to wrap outward at conductor 1, annealing copper wire and insulating layer 2 constitute the sinle silk, two and more than two sinle silk transposition constitute the cable core, it has non-hygroscopicity material 3 to fill in the cable core clearance, the cable core is wrapped outward and is had non-hygroscopicity band 4, the shielding layer 5 that the copper wire constitutes is woven outward in non-hygroscopicity band 4, 5 crowded wraps oxygen 6 layers outward on shielding layer, prevent flame spreading when making the cable conflagration take place, reduce loss of property. Preferably, the oxygen barrier layer 6 is a high flame retardant type oxygen barrier layer. An armor layer 7 is woven outside the oxygen isolation layer 6, and a flexible cross-linked polyvinyl chloride high-flame-retardant sheath 8 is extruded outside the armor layer 7.
Preferably, the armor layer 7 is formed by weaving galvanized steel wires with the diameter of 0.15-0.30mm, and the armor layer 7 is soft in structure, easy to bend, pressure-resistant and compatible with ground wire drainage.
In this application, insulating layer 2 and sheath 8 adopt crosslinked polyvinyl chloride material, and this material compromises the advantage of polyvinyl chloride and crosslinked polyethylene between them, reaches the perfect adaptation of intensity and toughness, and material wearability, fire resistance, ageing resistance and acid-base nature are all relatively good, make the life of cable increase, reduce the cycle replacement rate of product.
