Copper Clad Aluminum Cable Price Description
Due to the soaring copper material in recent years, it has brought great pressure to the cable manufacturing industry. The large increase in cable prices has made it unacceptable for a considerable number of users, and even caused economic disputes and project delays; small manufacturers have stopped production. A large part of the manufacturers that can produce normally also rely on reducing raw materials to maintain price competition. Many manufacturers' low-voltage cable copper conductor cross-sectional area only reaches 80%-85% of the national standard. Caused a lot of quality hidden dangers to the user.
In the face of this background, our company has developed and produced copper-clad aluminum power cables based on the original production of copper-clad aluminum conductors (see company product promotional materials for specific performance). Compared with the original copper cable, the price of the copper-clad aluminum cable with the same square and the same number of cores is only about 60% of the original copper cable. If the copper-clad aluminum cable needs to achieve the same DC resistance and current carrying capacity as a copper cable of a certain specification, then the cable The price is only about 70% of the copper cable of this specification. Our company guarantees that the square cross-section of the copper-clad aluminum cable produced meets the standard (positive tolerance).
Copper-clad aluminum alloy wire (CCA) is a product of the 95 Spark Program promoted by the state and the third-generation conductor after copper and aluminum promoted by the Ministry of Information Industry. It has good conductivity, high strength, strong weldability, and specific gravity. It is 3.32g/mm3~3.63g/mm3, the DC resistivity is 70% of pure copper, and the length is 2.5~2.7 times that of pure copper with the same area and the same weight.
For example: (take the Yangtze River copper price of 65,000 yuan/ton on August 26, 2007 as an example)
① Market reference price of copper cable VV3×25+1×162: 63.20 yuan/m;
② Copper-clad aluminum cable VVC3×25+1×162 Market reference price: 34.23 yuan/m
