ABSTRACT:
An insulated wire having a controlled specific gravity is provided. The wire is manufactured by surrounding an electrical conductor with a layer or a closed cell foam and a sheath. The density and outer diameter of the layer of closed cell foam are controlled to provide the desired overall specific gravity of the insulated wire so that the insulated wire will float on the interface between two immiscible fluids which have different specific gravities.
