This part of IEC 60317 forms an element of a series of standards which deals with insulated wires used for windings in electrical equipment. The main objective of the series is to ensure winding wires offer optimum electric strength and service life, and minimize risk of product failure.
BS EN IEC 60317-27-3 specifies the requirements of paper tape-covered rectangular copper winding wires. This covering consists of two or more layers of paper tape and is primarily intended for winding coils for oil-immersed transformers.
BS EN IEC 60317-27-3 on particular types of winding wires is relevant to:
Enamelled copper wire is an insulated copper wire electrical conductor used in motors, transformers, and other electromagnetic equipment. The reason behind using the enamelled copper wire is to avoid the surface of the wires from being caught in any short circuit when it has been wound into coils. In this regard, paper tape covered
BS EN IEC 60317-27-3 describes the requirements and specifications for paper tape-covered wires in transformers. The insulating paper tape covering the wires creates magnetic fields and reduces the risk of short-circuiting from current flowing through it.
If you are a manufacturer, BS EN IEC 60317-27-3 can help you make the right choice based on the purity, grade and thickness of the insulation paper that essential to achieve the necessary electrical strength.
