The utility model has the technical scheme that the ethylene-propylene rubber insulated rat proof flexible cable comprises a central conductor, an insulated layer coating on the periphery of the central conductor, an insulated layer extruded outside the insulated layer, and a screening layer, a water stopping layer, a fire proofing layer and a jacket layer which are wound on the periphery of the insulated layer; a cable section forms a multi-layer concentric circle structure and includes a rat proof layer woven on the periphery of the water stopping layer and positioned between the water stopping layer and the fire proofing layer; the central conductor includes a plurality of cores; each core is composed of a plurality of type V flexible copper conductors or type VI flexible copper conductors; and the water stopping layer is a double-face structure which is wound by the double-face water stopping belt.
Description
Technical field
The utility model relates to a kind of cable, relates in particular to a kind of ethylene propylene rubber insulated protection against rodents flexible cable.
Technical background
Single-core cable is a most widely used class cable in the cable model, and single core flexible cable is widely used in important places such as subway, nuclear power station, market, hospital, intelligent building.The architectural characteristic of single core flexible cable has determined a little less than its insulation protection relatively; external force resistance impact and damaged by rats ability are relatively poor; but one of China country that to be the plague of rats more serious; development along with China's electric utility; circuit is more and more intensive; but mouse stings bad power cable causes the accident of electric short circuit often to take place, and has seriously influenced the normal operation and the safe power supply of power cable line, and above-mentioned occasion is in case dare not imagine because of damaged by rats causes the short circuit consequence.
Traditional oversheath mouse bite preventing mainly is to have added poisonous chemical addition agent in oversheath, and environmental pollution is bigger.Therefore demand developing that a kind of softness is good, external force resistance impacts and the strong single core protection against rodents flexible cable of damaged by rats ability urgently.
Summary of the invention
The utility model has overcome deficiency of the prior art, and a kind of ethylene propylene rubber insulated protection against rodents flexible cable is provided, and has good flexibility, and is non magnetic, corrosion-resistant, intensity is high, the strong characteristics of the strong and anti-damaged by rats ability of external force resistance impulsive force.
The utility model is achieved by following technical proposals:
A kind of ethylene propylene rubber insulated protection against rodents flexible cable, comprise center conductor, the peripheral wrapped separator of described center conductor, the insulating barrier that described separator periphery extrudes, the wrapped successively screen in described insulating barrier periphery, water blocking layer, flame-retardant layer and restrictive coating, the described cross-section of cable constitutes a multilayer concentric circle structure, it is characterized in that, also comprise between water blocking layer and flame-retardant layer, be woven in the protection against rodents layer of water blocking layer periphery, described center conductor is made of the multi beam core, every bunch core is made of the 5th class soft copper conductor or the 6th class soft copper conductor by some, and described water blocking layer is that bilateral structure forms by two-sided waterstop is wrapped.
Above-mentioned a kind of ethylene propylene rubber insulated protection against rodents flexible cable, wherein insulating barrier adopts the ethylene-propylene rubber material.
