Technical field
The utility model relates to cable technology field, particularly a kind of branch cable.
Background technology
Domestic branch cable used is almost entirely complete is at present copper conductor, along with the development of building industry and the development of business, the number of plies of building is more and more, highly increasing, and the length of branch cable is also thereupon increasing, because its conductor is copper conductor, this has just increased the deadweight of whole cable itself, in the process of installing and use, due to cable dead weight, easily occur that cable is pulled and the potential safety hazard such as open circuit.If but adopt fine aluminium cable, although alleviated deadweight, fine aluminium cable with respect to copper cable have that resistivity is high, poor ductility, intensity be also be not as large as shortcomings such as copper cable.
So need now a kind of novel cable for the problems referred to above, can address the above problem.
Utility model content
The technical problems to be solved in the utility model is to provide the fire-resistant aluminium alloy branch cable of a kind of environmental-protection flame-retardant, and this aluminium alloy is led branch cable from heavy and light, and price is low, has good mechanical performance, electrical property, creep-resistant property.
For addressing the above problem, the technical scheme that the utility model is taked is to provide the fire-resistant aluminium alloy branch cable of a kind of environmental-protection flame-retardant, comprise conductor, described conductor adopts the 8000 series alloys wires that specify in ASTM B800-05, and conductive surface is surrounded with double-deck synthetic mica tape, fire-retardant IXPE insulating barrier, the cotton packed layer of alkali-free glass fibre, alkali-free aramid fiber glass fabric and low-smoke halogen-free polyolefin sheath from inside to outside successively.
Preferably, described conductor adopts 8176 and 8030 aluminium alloy conductors that specify in ASTM B800-05.
Preferably, the quantity of described conductor is 4, line between the central point of described four conductors on same cross section is square, and the wrapped cross section of alkali-free aramid fiber glass fabric is circular, and described alkali-free glass fibre cotton is filled in the space between alkali-free aramid fiber glass fabric and conductor.
ASTM B800-05 is American Society Testing and Materials (American Society for Testing and Materials, ASTM) standard, Chinese name: electric by annealing and average tempering 8000 series alloys wire standard criterions.8000 series alloys wires one have 6 trades mark, are respectively 8017,8030,8076,8130,8176 and 8177.The mechanical performance of 8000 series alloys wires and physical property are all equal to or are better than copper conductor.
The beneficial effect that adopts technique scheme to produce is: (1) this aluminium alloy is led branch cable conductor and adopted the 8000 series alloys wires that specify in ASTM B800-05 to substitute conventional copper product, so both can reduce costs, again can weight reduction, increase percentage elongation, compared with the copper conductor branch cable of replaceable specification, gravity energy alleviates half left and right.(2) mechanical performance of aluminium alloy conductor, electrical property, creep-resistant property etc. can compare favourably with alternative specification copper conductor completely, and double-deck mica tape has good insulation property, hardness and water resistance, water-fast pouring and impact resistance; Glass fibre cotton good insulating, thermal endurance is strong, corrosion resistance good, and mechanical strength high (3) is in price, and the price of aluminium alloy branch cable, compared with alternative specification copper cable specification, can reduce the cost budgeting of 30% left and right.
