Abstract

PURPOSE: To provide the titled tape which has excellent corona resistance, dielectric strength, etc. and whose winding operation is easy, by a method wherein a fibrous insulating base material and a laminated mica foil are simultaneously subjected to a paper making process to prepare a sheet which is then treated with a thermosetting resin.
CONSTITUTION: 3W30wt% Fibrous insulating base material (A) such as fiber fabric tape (knitted by plain weave or twill weave) or a fiber (which is not knitted and simply arranged along the length of tape), 97W70wt% laminated mica foil (B) having an average dimension of 0.05W5mm, and pref. further 0.5W5wt% (based on the amount of the component B) high-molecular fibrid (C) (e.g. polyamide fibrid) are subjected simultaneously to a paper making process to prepare a sheet. The sheet is treated with a thermosetting resin such as a polyamide resin or an epoxy resin, and pref. further is subjected to a thermal contact bonding treatment to form the desired tape.
