Description
Technical field
This utility model is related to field of cable technology, more particularly, to cross-linked polyolefin insulation halogen-free low-smoke flame-proof damp-proof type electricity
Cable.
Background technology
Transform the quickening of paces and each with the rapid growth of Chinese national economy, particularly rural area and Construction of Intercity Network
Ground real estate flourish, the electric utility of China is developed rapidly, thus promoted matching for power industry
Electrician trade, the especially development of wires and cables industry, the Cultivar development of electric wire presents diversified trend.Electric wire
Cable develops to multifunction from simple power transmission, has been attached some new spies respectively according to different purposes
Property.For example：Flame retardant cable, fire-resisting cable, low smoke and low halogen cable, low smoke, zero halogen cable etc..
In recent years, the cable laying under rugged environment and moist environment, there is a growing awareness that cable-flame retardant
With moistureproof importance.Power cable mostly adopt directly buried installation mode, so cable bear come from ground pressure and due to
Anthropic factor and be subject to the probability that external force is damaged very big, water internally invades from breakage or joint, then to cable two
End diffusion, causes cable electrical property to decline.Alternatively possible：Cable storing, carry, lay, in running, due to accident
Acted on by mechanical force, and so that cable sheath is damaged, water is internally invaded from breakage, then spreads to cable two ends, causes
Cable electrical property declines.When cable is installed in a humid environment, without good stop water, then cable is easier
Being invaded by moisture, thus causing the destruction insulated, so will be greatly shortened the life-span of cable, in order to reduce water in environment
Divide the impact of various performances to cable and the infringement of cable itself, so the cable being laid in wet environment is typically necessary
Cable has moisture-proof construction.
Cable there is also ablaze risk, and this brings very big potential safety hazard to circuit.Cable is under burning condition
Still the problem that this circuit normal work for a period of time is that current cable industry is actively studied can be maintained.Generally
It is that, just in case catching fire, cable will not once just burn, and loop is safer.Though existing flame retardant cable can play certain effect,
But fire resisting effect on driving birds is not good, when the intensity of a fire is larger, is still unable to reach the function of fire resisting.Single flame-retardant layer cannot ensure the resistance to of cable
Fiery effect, the complicated environmental requirement cable that lays has higher refractory ability, therefore, the fire-resisting cable guarantee of comprehensive improvement
Cable adapts to adverse circumstances.At present, the general method adopting of flame-retardant electric wire and cable is exactly to add to contain halogen in sheath material
Halogenide and metal-oxide, to evaluate from fire-retardant angle, this is fabulous method, but, contain due in these materials
There is halogenide, discharge substantial amounts of smog and hydrogen halide in burning, so, low visibility during fire, the peace of the person of giving people
Full evacuation brings very big obstruction with fire-fighting, and people then more dies of asphyxiation for toxic gas.

As preferred version of the present utility model, described screen layer is included by the copper foil layer of inside and outside setting, aluminium foil layer.With now
Technology is had to compare, the beneficial effects of the utility model are：
1st, outer jacket includes setting gradually flame-retardant layer, damp-proof layer, oversheath from inside to outside, flame-retardant layer include from inside to outside according to
The carbon composite layer of secondary setting, magnesium oxide flame-retardant layer, outer mineral wool rope, crosslinked polyolefin layer, damp-proof layer includes the outer cloud of inside and outside setting
Master tape, glass layer.Setting carbon composite layer, magnesium oxide flame-retardant layer, outer mineral wool rope, crosslinked polyolefin layer, energy in outer jacket
The comprehensive flame retardant effect improving cable, being stacked of four layers of fire proofing, can farthest play the effect of material.Moistureproof
The outer mica tape of layer, glass layer can be effectively moistureproof, it is to avoid the bad situation of normal cable moisture effect.
2nd, be additionally provided with sheath between screen layer and protective metal shell, sheath include inside and outside setting interior damp-proof layer, every
Thermosphere, interior damp-proof layer includes the nonwoven layer of inside and outside setting, interior mica tape, thermal insulation layer include inside and outside setting aeroge carpet veneer,
Interior mineral wool rope, Ceramic silicon rubber twining package tape.Interior damp-proof layer can protect cable endothecium structure from erosion, improves the synthesis of cable
Moisture protection.When thermal insulation layer is avoided that cable is in hot environment, the feelings that ability to work declines because endothecium structure temperature rises
Condition.
