A neutral wire, is a type of flexible conductor, usually consists of a multi strand copper wire, one or two samll wires as optional, and two copper lugs, which are brazed together. We usually put silicon tube, heat-shrink sleeve, or PVC coat to the multi strand wire and provide customized cable of complicated structures.
The neutral wire can serve as the flexible busbar or primary wire which is usually work with a miniature current transformer or other components. We can also replace a copper lug by manganin plate and make a primary wire type shunt. As we manufacture these parts by automatic cutting machines and high-speed stamping machines, we can provide very competitive price for large-scale production.
