At present, in the power transmission and transformation project of national grid, cables are usually composed of stranded wires, which are formed by transposing a single conductor. When making such stranded wires, pipe strander is usually used. The pipe strander can transpose copper wire, aluminum wire or steel wire to form stranded wire.

In fact, tubular Strander is a relatively simple machine with low cost. It is a good choice for enterprises with high output, and it saves money for new cable factories. Because of its low cost, high production efficiency, wire stranding machine is very popular with users. But in other daily production, although its maximum speed can reach 800 rpm, it is impossible for us to reach it in daily use This speed is very serious for the loss of the machine. The general practical range of speed is 400-500rpm, which is suitable. There are many manufacturers producing this kind of machine in China, and the quality is different. When customers choose, they must consider the history of the factory and the production quantity of the pipe winch in a year, because the more sales, the more mature its technology, the quality can be guaranteed.
