Aluminum alloy cable cable 5 big performance

Safety performance aluminum cable : Performance of a
1 , history proved 3 , aluminum alloy composition effect ;
After adding rare earth alloy conductor components and iron and other ingredients, greatly improved the performance of its electrical properties and connections , especially when you add iron to produce annealed conductor creep resistance of high strength , when current overload, iron play continued connecting role in making aluminum conductor creep does not occur.
Creep great harm to the cable , if Terminal BLOCK  the cable creep , its original point of contact pressure is not tight enough , the pressure is reduced so that the contact resistance increases rapidly after the current flow caused by overheating of the joints , if unscheduled maintenance, there will be security risks . Is very important to solve the problem of cable creep .
Creep: metal temperature , force and its own weight , over time , permanent deformation will not be slow to recover , the phenomenon of creep.
Flame retardant
Aluminum retardant cable insulation materials using silane cross -linked polyethylene (XLPE), the use of self-locking armored structure, thermal performance is far superior to PVC jacket material can rapidly heat the process, the flame disappears quickly extinguished the flames , then do not delay other materials , very excellent flame retardant properties . Aluminum cable using new materials and new technology , to ensure its use more secure.
Performance II: Electrical properties of aluminum cable
1, the cross-sectional area cable ampacity copper alloy conductors are 1.5 times the copper alloy conductors and  mini usb cable electrical properties as a conductor to achieve the same carrying capacity , resistance, and pressure loss .
The resistance between the aluminum alloy of aluminum and copper, aluminum slightly higher , but lower than copper , provided at the same flow cross section , the weight of the aluminum alloy conductor of equal length is only half the copper . If the conductivity of the copper at 100 %, the conductivity of the conductor is about 61.2% of the alloy , the proportion of the alloy is 2.7 , the proportion of copper is 8.9 , the (8.9/2.7) × (0.612 / 1) = 2, i.e., 2 the unit weight of the same alloy with a resistor of resistance of copper per unit mass , so that when the cross-sectional area of ​​the alloy is 1.5 times that of copper conductors is the same as the electrical properties , i.e. to achieve the same cross-sectional flow and copper , resistance, and voltage loss.
