ABSTRACT:
A multiple spiral tube assembly having a plurality of nested tubes, each of a different size and made of an insulating material. One tube is inserted within another tube to form a flexible, multiple-layer tube assembly. The tubular assembly is slipped over an electrical conductor to form a flexible, multi-layer, thick wall construction for coil lead insulation.
