GB/T 6109.2-2008 Enamelled round winding wire -Part 2: Polyester enamelled round copper wire, class 155
1 Scope
This part of GB/T 6109 specifies the requirements of enamelled round copper winding wire of class 155 with a sole coating based on polyester resin, which may be modified provided it retains the chemical identity of the original resin and meets all specified wire requirements.
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.
Class 155 is a thermal class that requires a minimum temperature index of 155 and a heat shock temperature of at least 175 °C.
The temperature in degrees Celsius corresponding to the temperature index is not necessarily that at which it is recommended that the wire be operated and this will depend on many factors, including the type of equipment involved.
The range of nominal conductor diameters covered by this part is as follows:
- grade 1: 0.020mm up to and including 3.150 mm;
- grade 2: 0.020 mm up to and including 5.000 mm.
The nominal conductor diameters are specified in Clause 4 of GB/T 6109.1-2008.
