Abstract
The present invention discloses a light low smoke zero halogen wind energy cable and a preparation method thereof, belonging to the cable field. The light low smoke zero halogen wind energy cable comprises an aluminum alloy conductor, an EPR insulation layer, a polyester film tape, a soft copper wire braided shielding layer, a fire-resistant halogen-free non-woven fabric tape and a thermosetting low smoke zero halogen outer sheath layer. The cable has the characteristics of light weight and small bending radius and can be adapted to the requirement of cable conductor long-term allowable working temperature minus 40 DEG C to 110 DEG C, a fan is allowed to work in changing and poor environments, and the cable has advantages of softness, abrasion resistance, oil resistance, and low temperature resistance.
Description
Technical field
The present invention relates to a kind of cable, particularly the light-duty low smoke and zero halogen wind energy cable of one, the invention still further relates to the preparation method of this light-duty low smoke and zero halogen wind energy cable.
Background technology
The copper core cable of China almost occupies more than half rivers and mountains of cable market at present! The copper resource of China is congenital rare, market supply and demand deficiency causes copper valency to remain high, when identical ampacity, the weight of aluminium alloy cable is approximately the half of copper cable, and copper core cable installation cost is high, difficulty of construction greatly, easily aging etc., replace copper cable with aluminium alloy cable, the weight of cable can be alleviated, reduce installation cost, the wearing and tearing of minimizing equipment and cable, make installment work more light.So far, wind energy cable continues to use traditional copper core cable always.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of light-duty low smoke and zero halogen wind energy cable, can substitute copper core wind energy cable completely, and cost is low, difficulty of construction is little, not easily aging.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of light-duty low smoke and zero halogen wind energy cable, comprises aluminium alloy conductor, ethylene propylene rubber insulated layer, mylar tape, the shielding of soft proof copper-wire braided, fire-resistant Halogen nonwoven fabric belts and heat curing-type low smoke and zero halogen outer jacket.
Further: described aluminium alloy conductor adopts 8000 series alloys, conductor structure meets the requirement of GB/T3956-2008 the 2nd class conductor.
Further: the wrapped Duplication of described mylar tape is arranged between 10% ~ 15%.
Further: the minimum count of described soft proof copper-wire braided shielding is not less than 70%.
Further: heat curing-type low smoke and zero halogen outer jacket adopts ethylene vinyl acetate rubber, and wherein vinyl acetate content controls the scope 50% ~ 80%.
The invention has the beneficial effects as follows: lightweight, cost is low, bending radius is little, can meet the basic demand that blower fan uses under the environment such as changeable, severe.In addition, the present invention also has low smoke and zero halogen, high flame retardant, wear-resisting, the characteristic such as oil resistant, softness, normally can use under the condition of ambient temperature-40 DEG C ~ 110 DEG C.
