Description

A kind of stretch-proof copper stranded conductor with superpower oxidation resistance

Technical field

The utility model relates to a kind of process units, specifically a kind of stretch-proof copper stranded conductor for the production of having superpower oxidation resistance.

Background technology

Copper stranded conductor can be divided into hard drawn copper strand wire and annealed copper strand wire according to its soft durometer, the tensile strength of hard drawn copper strand wire is high, hardness is high, it has copper stretching cold working to form, annealed copper strand wire on the basis of hard drawn copper strand wire, removes wherein remnants by heating form, soft flexible compared to hard drawn copper strand wire, can bend.The different qualities of hard drawn copper strand wire and annealed copper strand wire, they are used in different field respectively, hard drawn copper strand wire is because its tension stress is durable by force, resistance is little to conduct electricity very well, need conduction so be often used in and on tension force, require higher place, the conductor of such as distribution wire and building, also has the cable aspect of overhead power transmission.But annealed copper strand wire is usually thin than hard drawn copper strand wire, its conductivity is high especially, and it is widely used in the electrical appliance wire of adding some points, and is also applicable on electricapparatus, as power cable and Communication Equipment conductor.

But annealed copper strand wire is comparatively thin by copper wire in the inner, and the temperature of electrical equipment inside after long-term work is higher; the copper stranded conductor that can be usually is oxidized; cause its surface discolouration, cause it to rupture in use for some time, high-temperature oxydation substantially reduces the useful life of copper stranded conductor.Thus, for today of electrification, solve copper stranded conductor high-temperature oxydation problem extremely urgent.
