What is BS EN IEC 60317-27-4about?
This part of IEC 60317 forms an element of a series of standards which deals with insulated wires used for windings in electrical equipment.
BS EN IEC 60317-27-4 specifies the requirements of paper tape covered round aluminium winding wires. This covering consists of two or more layers of paper tape and is primarily intended for winding coils for oil-immersed transformers.
Who is BS EN IEC 60317-27-4 for?
BS EN IEC 60317-27-4 on winding wires is relevant to:
- Aluminium wire manufacturing industries
- Power and distribution transformer manufacturers
- Manufacturers of electrical applications
- Electrical engineers
- Mechanical industries
Why should you use BS EN IEC 60317-27-4?
Aluminium provides a better conductivity to weight ratio than copper and is therefore used for wiring power grids, including overhead power transmission lines and local power distribution lines.
BS EN IEC 60317-27-4 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 to the requirements and processes with BS EN IEC 60317-27-4 is beneficial as it defines methods for improving the efficiency of applications by using wire with paper insulation that can prevent product failure and overall product damage.
Making the right choice based on the purity, grade and thickness of the insulation paper is essential to achieve the necessary electrical strength.
