The selection of wire for PT/CT applications requires careful consideration of insulation type, thermal class, and wire gauge. All wires produced in our factory comply with IEC 60317 standards. Various sizes and different heat resistance grades are available.
Generally, the main wire sizes used range from AWG 4 to AWG 34. Examples of popular sizes are as follows:
| AWG Size | Diameter (mm) | Typical Application |
| AWG 8 | 3.26 | High-current primary windings |
| AWG 12 | 2.05 | Medium-power applications |
| AWG 16 | 1.29 | Control circuits |
| AWG 17 | 1.15 | Secondary windings |
| AWG 30 | 0.255 | Precision low-power winding |
| AWG 31 | 0.227 | Micro-coil applications |
| Parameter | Specification |
| Applicable Standard | IEC 60317 |
| Insulating Enamel Type | Polyesterimide |
| I.A.C.S Copper | 100% |
| Grade | 2 |
| Thermal Class | H / 200°C (checking for 155°C & 180°C Optional) |
Polyesterimide enameled copper wire consists of a copper conductor coated with a polyesterimide insulation layer.
We usually sell 200°C rated wires and optional enameled copper wire with different thermal ratings (155°C and 180°C). Comparison is as follows:
| Thermal Class | Maximum Temperature (°C) | Application Suitability |
| Class H | 200 | High-temperature environments |
| Class F | 180 | Moderate temperature rise |
| Class B | 155 | Standard applications |
