IEC 60317-80:2019 pdf free download Specifications for particular types of winding wires – Part 80: Polyvinyl acetal enamelled rectangular copper wire , class 1 20 , with a bonding layer
1scope
This part of lEC 60317specifies the requirements of enamelled rectangular copper winding wireof class 120 with a dual coating.The underlying coating is based on polyvinyl acetal resin,which can be modified providing it retains the chemical identity of the original resin and meetsall specified wire requirements.The second coating is a bonding layer based on a thermoplasticor thermosetting resin.
NOTEA modified resin is a resin that has undergone a chemical change,or contains one or more additives toenhance certain performance or application characteristics.
The range of nominal conductor dimensions covered by this document is:- width:
min.2,00 mm
max.16,00 mm;
– thickness:
min. 0,80 mm
max. 5,60 mm.
Wires of grade 1 and grade 2 are included in this specification and apply to the complete rangeof conductors.
The specified combinations of nominal width and thickness as well as the specified ratiowidth/thickness are given in lEC 60317-0-2:2019.

3.1 Terms and definitions
For the purposes of this document, the terms and definitions given in lEC 60317-0-2:2019 apply.
Iso and lEC maintain terminological databases for use in standardization at the followingaddresses:
3.2General notes
3.2.1 Methods of test
Subclause
3.2.1 of lEC 60317-0-2:2019 applies. In case of inconsistencies between lEC 60317-0-2:2019 and this part of lEC 60317, this document lEC 60317-80 shall prevail.
3.2.2Winding wire
Class 120 is a thermal class that requires a minimum temperature index of 120 and a heatshock temperature of at least 155C.
The temperature in degrees Celsius corresponding to the temperature index is not necessarilythat at which it is recommended that the wire be operated and this will depend on many factors,including the type of equipment involved.
