1, Use:
Aluminum wire and ACSRs structures are simple. They are easy to set up and maintenance. The cost is low in building the lines. The transmission capacity is large. They are also convenient to cross special geographical conditions, such as rivers, valleys and so on. So the products are applied for various voltage levels of overhead transmission and distribution lines.

GB/T1179-1999 "Round wire concentric lay, stranded conductors" standard is equivalent to IEC61089-1991 standard. According to user needs. Our company can produce the aluminum wire and ACSR on the basis of ASTM, DIN, BS and other standards. Note: the products model and code in GB1179-83 of the new and old standard still has a large number of users and market, it can be used as non-standard£¨or users special needs£© when ordering the products.
3, material standards:
Aluminum wire and ASCR with a hard steel core execute GB/T17048 (identical with IEC60889 standard). ACSR with galvanized steel execute IEC60888 standards. According to users needs, we can produce the production on the basis of the user's material standards and requirements.
4, product performance: the electrical properties of aluminum wire and ACSR should be showed as the resistance at 20 ¡æ. Hard aluminum wire's resistance is not greater than the international standard value 0.028264¦¸.mm2 / m. ACSR has three intensity levels: general intensity level ACSR, high strength ACSR and extra high strength grade level ACSR.
5, product maintenance: the product should avoid squeezing and bumps during handling and transportation. Cables should not be laid flat during the transportation and storage. Product should take moisture measures during storage.

1. Strand wire should have the same diameter, the same intensity, and the same level of zinc coating.
The diameter and the lay length should be uniform, and have no loose after cutting
Strand wire should be tight; they should not be staggered, and have no breaking and bending.
2. Strand wire and the overhead ground wire of 1 * 3 are not allowed to connected, other types of strand wire should be connected with welder. The distance between any two joints shall not be less than 50m; the measures should be taken to prevent the joints eroding.
3. Mechanical Properties
it should follow the 5.3 mechanical requirements in "People's Republic of ferrous metallurgy industry standard YB/T5004-2001.
4. Coating quality
4.1 Galvanized steel's surface should be coated with uniform continuous layer of zinc, without cracks and open spots
4.2 Zinc coating of the steel can have white spots, flash point and the individual accumulation of zinc layer, but can not affect the use. But the value of the local wire must not exceed 2 times as large as the positive deviation of the diameter.
4.3 The coating quality of the strand wire with the split shares should meet the following table:
Nominal steel diameter MM Coating mass/(g/©O)
Not less than
Around the core posts
The diameter should be steel
The diameter should be multiple

4.4 The zinc coating should be firmly enlaced 6 laps on the mandrel in the above table, no cracking or the zinc coating layer. It can not be able to wipe with the extent of bare fingers.
5. Refer to "the People's Republic of ferrous metals industry standard YB/T5004-2001 galvanized steel wire¡±.
"People's Republic of ferrous metallurgy industry standard YB/T183-2000 strand of rare earth alloy coating¡±.
(B) The raw materials
1. The steel of the strand wire shall be used in the requirement of YB/T699-1999. The steel grades are 5 # or 50 #.
2. Zinc ingot, used in galvanized steel wire, should use the zinc in GB/T470 of 0 or 1.
(C) Factory inspection and testing methods
all the factory inspections are divided into full inspection and spot inspection. Full inspection requires checking the appearance, structure, diameter, galvanized coating mass, twist method and its quality of each steel stranded wire.
1. Inspect the surface quality of the strand by visual inspection.
2. Use the measuring tool of 0.1mm to inspect the diameter of the strand.
3. Breaking load test is required according to the standard GB/T8358-1987.
