Ductility resistance: the aluminum alloy cable tray is 40 lower than the copper cable, which is more conducive to the fastening of the connecting terminal and the fastening of the contact end of the connecting end.
Corrosion resistance: the corrosion resistance of cable tray in the air is better than that of copper. The application life of copper cable is planned as a whole for 30 years, and the application life of cable tray can reach 40 years, which is also based on the objective fact of application in the United States.
Bump function: according to the division of bumpy half diameter of copper cable equipment in GB/T12706, the bumpy half diameter of copper cable is 10-20 times the cable diameter, and the bumpy half diameter of aluminum alloy cable bridge is not more than 7 times the cable diameter. The application of cable bridge reduces the indoor space for reasonable layout of equipment, reduces the equipment cost, and is more installation and laying.
Conductivity: according to GB/T3956, aluminum alloy profile electrical conductor is compared with copper electrical conductor plus one or two specifications and models to reach the same cable current carrying capacity, that is, the cross section of aluminum alloy profile plus 1.5 times to reach the same conductivity of copper. The natural cross section is increased by 1.5 times, but the diameter of electric conductor is only added by 1-18mm compared with that of copper, which is very small.
Plasticity: the tensile strength of aluminum alloy cable tray after annealing can reach or exceed 30%, which is higher than the 25 specification of copper cable.
Weight: aluminum alloy cable tray with the same cable carrying capacity and size is half the weight of copper cable. It has obvious advantages in large-span equipment and can reduce equipment cost.
