ABSTRACT:
A submersible motor having a primary winding made of a water-tight wire has an improved life characteristic. The water-tight wire is made of a conductor and three layers formed on the conductor. The three layers are a heat-resistant enamel layer, a main insulating layer and an outer protective layer. The main insulating layer is composed of crosslinked polyethylene or a polypropylene. The outer protective layer is composed of a polyvinyl chloride composition having as a base material a polyvinyl chloride having a number average polymerization degree of 2000 or higher.
