Aluminum alloy conductor high-strength high-conductivity flame-retardant XLPE insulation aluminum alloy strip metal-clad PVC sheath cable

ii ) : Description

 1. Applications

Used as bare overhead conductor for primary and secondary distribution. Designed utilizing a high-strength aluminum alloy to achieve a high strength-to-weight ratio; affords better sag characteristics. Aluminum alloy gives AAAC higher resistance to corrosion than ACSR.

2. The properties of aluminum alloy power cable 

(1)Under the same cross section, Aluminum alloy conductor weight is 50% to copper core cable ,

 as their specific gravity is significant different, even if aluminum alloy cross sections will be enlarged, it also can reduce the conductor weight as its small specific gravity.

 (2)Good joint properties: as add the Fe, Mg, rear earth ect. into aluminum: significantly improved the toughness and high anti creep property after annealing. In fact, the joint of copper and aluminum is the most key problems all the time. If copper and aluminum (or aluminum alloy) connect directly; connection contact, as the different materials, existing potential difference, in humidity air can occur electric chemical corrosion. In power system, this corrosion can increase contacting resistance, making the joints heat and become potential danger of system operate safely. Now apply the new technology copper aluminum joint, and eliminate the fatal defect caused by old copper aluminum joint thoroughly, making joint of aluminum alloy cable safe and easy to install.

 (3)Improved mechanical properties: as add the alloy Fe, Cu, rear earth ect. Into the purity aluminum, improved the aluminum alloy's comprehensive properties, elongation and creep properties.

 (4) To meet the same conductive performance, under the precondition of the same weight , aluminum alloy cable length is copper cable two times , therefore, the same load flow aluminum alloy cable weight is about half of the copper wire, Aluminum alloy cable to replace copper cable, the cable can reduce weight, reduce the installation cost, reduce equipment and cable wear, make the installation work more easily.
