What is BS EN IEC 60317-27-1 about?
BS EN IEC 60317-27-1 specifies the requirements of paper tape-covered round 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.
This part of IEC 60317 forms an element of a series of standard which deals with insulating wires used for winding in electrical equipment.
The range of nominal conductor diameters covered by BS EN IEC 60317-27-1 are:
- 0.500 mm up to and including 5.000 mm
Who is BS EN IEC 60317-27-1for?
BS EN IEC 60317-27-1on particular types of winding wires is relevant to:
- Copper wire manufacturing industries
- Power and distribution transformer manufacturers
- Manufacturers of applications that require electrical transference
- Electrical engineers
- Mechanical industries
Why should you use BS EN IEC 60317-27-1?
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 insulation is a good idea.
BS EN IEC 60317-27-1 describes the requirements and specifications for paper tape covered wires in transformers. Insulating paper covering all around the wires creates magnetic fields and reduces the risk of short circuiting from current flowing through it.
Compliance of requirements and processes with BS EN IEC 60317-27-1 is beneficial as it defines methods for improving the efficiency of applications by using wire with paper insulation that has good insulation properties thereby preventing electrical short-circuits. Making the right choice based on the purity, grade and thickness of the insulation paper is essential to achieve the necessary electrical strength.
