Abstract

PURPOSE: To obtain a high heat contraction characteristic in an extensive temperature range by arranging such that a heat contractile force working at its maximum in a low temperature range is kept smaller than a contractile force working at its maximum in high temperature range.
CONSTITUTION: An extensive temperature range heat contractile tape c1 is obtained through combining a fibrous material a1 like vinyl chloride which exerts its maximum contractile force in a low temperature range and a fibrous material b1 like polycarbonate which exerts its maximum contractile force in a high temperature range. A characteristic curve of the tape c1 for temperature and contractile force indicates a high contraction characteristic in an extensive temperature range to have a contractile force working small in a low temperature range but large in a high temperature range through a synthesized characteristic of both materials a1 and b1. From heating and molding that with an insulating layer impregnated with resin on the conductor wound by the tape c1 on its outer perimeter, a pressurizing action of the force of heat contractil material c1 is capable of giving a voidless and compact insulating layer.
