Product Description

Copper Clad Aluminum Wire(CCAW) is the new products replacing the previous generation, widely recommended by the country, taking the international advanced craftwork of cover welding.

It is the bimetal wire that makes the metallurgy combination of copper layer and aluminum-core wire, through the way of cover the copper layer on the aluminum-core wire. And also realize the copper layer spread to circumference and portrait way with balanced concentricity. The product is divided into soft and hard state in the way of statement, but 10 percent to 15 percent according to the volume of copper layer. And every technology index has met the IEC 61307-0-3 Standards.

Characters of Copper Clad aluminum wire:

1. DC Resistivity: The DC resistivity of copper clad aluminum wire is just 1.5 times than that of pure copper wire, and as the resistive rate is the same, copper clad aluminum wires weight is about half of the pure copper wire, so according to the skin effect, on the point of or above the 5MHz, the resistive rate is the same with pure cooper wire.

2. Well welded: Cooper clad aluminum wire has the good welding capability as the pure cooper wire for its surface covered with a layer of cooper.

3. With light weight: The weight percentage between the cooper clad aluminum wire and the pure cooper wire is just 37% to 40%, so under the circumstance of the same weight and wire size, its length is 2.5 to 2.7 times that pure cooper wire, which has lower the production cost. For example, buying one ton of copper clad aluminum wire is the same with buying 2.5 to 2.7 tons pure copper wire.

4. Soft quality of copper clad aluminum wire and easily processed
Copper clad aluminum wire is to clad bimetal compound lead on the aluminum stick coaxially, and after clad they should be suppressed so as to become various spectation, and forms a strong combined metal on the bank of copper and aluminum, making the lead as a whole.

Copper clad aluminum is well conducted as well as copper, but with higher intensity, lower density and other advantages, and also have coppers characteristic of equality of copper layer, high dense capacity and well stretched.

Copper clad aluminum wire is especially getting used to replace copper wire to work as the information transmission cable of CATV and communicative network with large capacity. Because the information transmitting frequency of TV and network is high, and information frequency is centered to the surface, so the transmitting effect is the same while the frequency is above 5Mc. Why copper clad aluminum wire is superior to pure copper wire is that it is convenient to transport and easier to process for soft quality, saving copper resource, with lighter weight and low production cost.

Copper clad aluminum wire is widely used in the transmission of CATV information, communicative network with large capacity, controlling the information cable, light cars cable, welding cable, emergence movement cable, TV exciting loop, deflecting loop, ballast loop and other aspects, Our factory can produce the thinnest wire products with Product conductivity of 20% to 70% and wire size of 0.10 to 1.0, to the demand of customers. Presently we have cooperated with many factories and produce 0.18 products steadily and makes it a key product.

The appliance scale of copper clad aluminum wire: CATV coaxial cable, coaxial frequency cable with soft capacity, audio frequency, video frequency wire, digital transmission wire cable, cars information wire cable, net-linking wire cable, other information transmission wire cable.
