Three core cord for electric machine and apparatus windings

摘要

The three-core cord is provided for the windings of electric machines and devices, particularly transformers. The cord or lead is made up of several individual, insulation coated, flat partial leads combined into a rectangular cross-section. The partial leads on both sides of the cross-section run at a slope in opposite senses. At the narrow sides of the cross-section, they pass through a right angle bend from one side to the other. At least one of the partial leads is wound with a glass fibre optic distribution probe embedded in a groove. The groove is preferably on the long side of the insulated partial lead. The depth of the groove encloses the probe flush with the partial lead.
