HPN (Heater Parallel Neoprene):
Application: These cables are specifically designed for heater-type appliances like irons, toasters, and hot plates.
Features:
- Parallel conductors: Conductors run side-by-side, allowing for higher current carrying capacity.
- Neoprene insulation: Offers superior heat resistance compared to standard thermoplastic insulation used in other cords. This is crucial for withstanding the high temperatures generated by heating elements.
- Voltage rating: Not typically specified for HPN cables, as they are primarily used in low-voltage applications within appliances.
HPN-R:
Application: This variety of HPN cables is suitable for both heater applications and general-purpose power cords. It inherits the heat resistance benefits of HPN while offering additional functionalities.
Features:
- Parallel conductors similar to HPN cables.
- Neoprene insulation for heat resistance.
- Voltage rating: Typically rated for 300 volts, making them suitable for various low-voltage power applications besides heating elements.
- Additional features: May include oil resistance and weatherproofing properties depending on the manufacturer.
