With the development of the power industry, power transmission via wires not only brings light to countless homes but has also become an indispensable part of daily life. Wires are made of aluminum alloy cables. Below is an introduction to aluminum alloy cable models and related common sense for your reference. 1. Common domestic aluminum alloy cable models: YJHLV; YJHLV8; YJHLV82; YJHLV22; YJHLV83 is also common in China.
2. Foreign aluminum alloy cable models: AC90, ACWU90, SER, SEU, RW90, RWU90, MC, UD-1350, UD-8000, MHF, XHHW-2, etc.
Additional Notes:
YJHLV (TC90) aluminum alloy cable, i.e., cross-linked polyethylene insulated, PVC sheathed aluminum alloy power cable, is an unarmored alloy cable.
YJHLV8 (AC90) aluminum alloy cable, i.e., cross-linked polyethylene insulated, aluminum alloy with interlocking armor, is a flexible, self-locking aluminum alloy cable.
YJHLV82 (ACWU90) aluminum alloy cable, i.e., cross-linked polyethylene insulated, aluminum alloy with interlocking armor, is a PVC sheathed aluminum alloy power cable. Sheathed aluminum alloy power cable is a flexible, self-locking aluminum armored alloy cable.
YJHLV22 aluminum alloy cable is a cross-linked polyethylene insulated, steel tape armored, and PVC sheathed aluminum alloy power cable, featuring a high-strength double steel tape armor.
YJHLY83 aluminum alloy cable is a cross-linked polyethylene insulated, aluminum alloy tape interlocking armored, and polyolefin sheathed aluminum alloy power cable, featuring a halogen-free, low-smoke, self-locking aluminum armored alloy cable.
III. Nine Key Properties of Aluminum Alloy
1. Creep Resistance
2. Tensile Strength and Elongation
3. Coefficient of Thermal Expansion
4. Connection Performance
5. Strong Deadweight Bearing Capacity
6. Corrosion Resistance
7. Flexibility
8. Armoring Characteristics
9. Compression Properties
IV. Applications and Standards of Aluminum Alloy Cables
1. Outdoor electrical loads (residential electricity) and pre-branched cables within buildings may be replaced with aluminum alloy cables, provided the local power bureau permits, meets current carrying capacity requirements, and is easily accessible. Disadvantages: Aluminum wire has a lower current-carrying capacity than copper wire. Switching to aluminum alloy cable will increase construction workload. Furthermore, the perennial humidity in outdoor pipe shafts can cause unnecessary corrosion to the aluminum wire, shortening its service life.
2. The current-carrying capacity, fire resistance, reliability, and installation environment requirements of aluminum alloy cables must be approved by relevant authorities. More about aluminum alloy cables
