Abstract
The utility model belongs to the technical fields of cables and in particular relates to an aluminum alloy branch cable. The aluminum alloy branch cable comprises a branch cable body, a main cable and a connecting piece, wherein the branch cable body is connected with the main cable by virtue of the connecting piece; and each of the main cable and the branch cable body comprises a conductor wire, an insulating layer, an outer protective layer, a conductor wire extrusion covered insulating layer and an insulating layer extrusion covered protective layer. The aluminum alloy branch cable is characterized in that the conductor wire is an aluminum alloy wire, wherein a flame retardant layer is arranged on the inner wall of the outer protective layer; and the flame retardant layer is arranged between the outer protective layer and the insulating layer. The insulating layer is made of cross-linked polyethylene. And the outer protective layer is PVC (Polyvinyl Chloride) with the temperature-resistant grade the same as that of the insulating layer. The aluminum alloy branch cable is light in weight, low in comprehensive cost, good in bending resistance, corrosion resistance, creeping resistance, and the like.
Description
Technical field
The utility model belongs to the cable technology field, relates in particular to a kind of aluminium alloy branch cable.
Background technology
Along with China's economic construction high speed development, high rising building stacks, and is more and more large for the demand of cable, and various material costs are also along with increase.at present, the high rise building cable is mainly take copper core or aluminium core as main, copper core branch cable expensive, quality is heavy, constructional difficulties, installation and use procedure are harder, and China's copper resource-constrained, although aluminium cable light weight, but the bending property of cable, creep-resistant property and decay resistance are relatively poor, meanwhile, often there is potential safety hazard in present cable, particularly overload might occur in the transmission of electricity process in cable, short circuit, contact resistance is excessive and run into the situation of external heat source, in short circuit, under the malfunctions such as local overheating and outer heat effect, the insulating material insulation resistance descends, lose insulating capacity, even burning, and then initiation fire, the safe operation performance is low.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides a kind of aluminium alloy branch cable, comprise branch cable body, leader cable, connector, described branch cable body is connected by connector with described leader cable, described leader cable, described branch cable body comprise respectively conductor silk, insulating barrier, outer jacket, the outer extruded insulation layer of described conductor silk, described insulating barrier extrudes outer jacket outward, it is characterized in that described conductor silk is aluminum-alloy wire, described outer jacket inwall is provided with flame-retardant layer, and described flame-retardant layer is arranged between described outer jacket and described insulating barrier.
The material of described insulating barrier is crosslinked polyethylene.
Described outer jacket is the PVC identical with described insulating barrier temperature resistant grade.
The beneficial effects of the utility model are: increase tensile strength and the elongation of wire, reduce integrated cost, than fine aluminium cable, the performances such as bending resistance, corrosion resistance, creep resistant are preferably arranged; Adopt the aluminium alloy branch cable to replace the copper branch cable, satisfying under the prerequisite of equal electric property, can alleviate cable weight, and the traditional copper core cable low 30% ~ 55% of cost ratio; Aluminum-alloy wire is nonmagnetic substance, has reduced the wearing and tearing of equipment and cable, makes installment work lighter.
