Overhead bare acsr conductor electric cable for transmission

ACSR (Aluminum Conductor Steel Reinforced) Cable consisting of galvanized steel core, which surrounded by concentric layers of aluminum wire, and grease if necessary.

 ACSR conductors are formed by several wires of aluminum and galvanized steel, stranded in concentric layers. The wire or wires which form the core are made of galvanized steel and the external layer or layers are of aluminum. Normally these conductors have a Galvanized steel core of 1, 7, 19 or 37 wires, surrounded by concentric layers of aluminum wires. The diameters of the steel and aluminum wires can be alike or different. By varying the relative proportions of aluminum and steel ratios, the ideal conductor can be produced for any particular application. In this way , if a high tensile strength conductor is required, the number of steel wires can be increased until the required strength is reached . When a conductor with high current carrying capacity and a comparatively low strength is required, this is attained with high aluminum content.

In comparison with copper, ACSR conductors have considerable technical and economical advantages in the installation of overhead lines. Its characteristics, and low weight, combined with its high breaking strength, are gathered which makes it possible to have large span runs, without having to revert to excessive mechanical stresses or to heavy metallic Towers. Due to the greater diameter of the conductors, electric losses by the corona Effect are greatly reduced. By making use of these properties economical electric energy transmission is attained at very high voltages and distances.

Different package for customer choose ! 

100% inspection for each process in cabling                                              

1, There is a professional design engineer team, before manufacturing, all of the product drawing will be approved by CSBTS (State Bureau of Quality Technical Supervision), and then the cable could be produced only if qualified.

2, To ensure the raw materials quality, all the copper are special-used for cable with the Inspection Certificates. The raw material is inspected when entering factory, and only the qualified material could be put in storage and used for production.

3, To ensure the product quality, there is a professional high level quality laboratory, most of the key technology date will be checked by high precision instrument.

 1. What kinds of products does Sitong CABLE manufacture?

2.Which markets do you involve mainly in?
Our products have been exported mainly to Australia, Russia, Africa, Middle East, South-east Asia, South America,Central America,North America, Europe ,Austrapa, etc.

3. Which standards do you comply with when you produce the electrical wires and cables ?
We are able to produce electrical wires and cables based on GB, JB, IEC, BS, DIN, ASTM, JIS, NF, AS/NZS, CSA, etc. Meanwhile, we can design and manufacture the cables according to the samples and technical specification the customer provided.

4. What is the min.order quantity ?
It depends on the type and size of electrical wires and cables. For some small electrical wires, 100 meters can be accepted .But for the power cables with medium or high voltage, that should comply with the property of installed equipments. Anyhow,we will try our best to solve the problem and meet with the requirement If you have special request.

5.What is the production capacity per week or per month ?
For the bare conductor, we can finish 3000 tons within one month. For power cables, that depends on the type and size. The total output value per month is approx. USD3,000,000.00 for insulated aluminum cables and that is approx. USD8,000,000.00 for insulated copper cables.
