Specifications for Particular Types of Winding Wires - Part 35: Solderable Polyurethane Enamelled Round Copper Wire, Class 155, with a Bonding Layer
|Publication Date:||1 October 2013|
|ICS Code (Wires):||29.060.10|
This part of IEC 60317 specifies the requirements of solderable enamelled round copper winding wire of class 155 with a dual coating. The underlying coating is based on polyurethane resin, which may be modified providing it retains the chemical identity of the original resin and meets all specified wire requirements. The superimposed coating is a bonding layer based on a thermoplastic resin.
NOTE A modified resin is a resin that has undergone a chemical change, or contains one or more additives to enhance certain performance or application characteristics.
The range of nominal conductor diameters covered by this standard is:
- Grade 1B: 0,020 mm up to and including 0,800 mm;
- Grade 2B: 0,020 mm up to and including 0,800 mm.
The nominal conductor diameters are specified in Clause 4 of IEC 60317-0-1:2013.
