Stranded Conductor

A conductor composed of individual groups of wires twisted together to form an entire unit. A number of wires are twisted together, usually built up on a single central conduc­tor with 6 wires in a first layer, 12 in a second, 18 in a third and so on. Most con­ductors therefore have 7, 19, 37, 61 or 91 wires. When there is more than one layer in a stranded conductor, the direction of lay is reversed in adjacent layers.
