Mutually insulated between conducting wire, and be often twisted into around a center, entire outside is surrounded by the coating of high-insulation, and cable has
Interior energization, the feature of external insulation.
Aluminium alloy power cable is twisted using special roll-forming molded line using AA8000 series aluminium alloy materials as conductor
The new material power cable of the advanced technologies innovation and creation such as production technology and annealing.Alloy power cable compensates in the past
The deficiency of fine aluminium cable, although not improving the electric conductivity of cable, bending property, creep-resistant property and corrosion resistance
Deng but greatly improving, it can ensure that cable is maintained continuous performance and stability in long term overloading and overheat, using AA-8030 series
Aluminium alloy conductor, conductivity, the heat-resisting quantity of aluminium alloy cable can be greatly improved, while solving fine aluminium conductor, creep etc.
Problem.The conductivity of aluminium alloy is the 61.8% of the most frequently used reference material copper IACS, and current-carrying capacity is the 79% of copper, is better than fine aluminium mark
It is accurate.But under the same volume, the actual weight of aluminium alloy is about the one third of copper.Therefore, aluminium alloy when identical current-carrying capacity
The weight of cable is about the half of copper cable.Copper cable is replaced using aluminium alloy cable, cable weight can be mitigated, reduction is mounted to
This, reduces the abrasion of equipment and cable, keeps installment work lighter.Current aluminium alloy cable fire protecting performance is poor, uses the longevity
Life needs to be further increased.
