Class 220 enameled polyurethane straight wire is a highly heat-resistant wire and cable suitable for power transmission and insulation applications in high temperature environments.

The insulation layer of grade 220 polyurethane enameled welding straight wire is made of polyurethane enameled material. Polyurethane has excellent heat resistance and electrical insulation properties and is suitable for cable insulation in high temperature environments.


Class 220 direct welding polyurethane enameled wire can generally work normally under high temperature conditions. It is typically rated for 220°C, which means it can withstand temperatures up to 220°C for extended periods of time without damage.

Due to the heat resistance of polyurethane insulation, 220-grade enameled polyurethane welding wire is suitable for winding high-temperature electrical equipment and motors, and can withstand the load current and insulation requirements in high-temperature environments.

As an insulating material, polyurethane has good electrical insulation properties, can effectively prevent leakage and electrical faults, and provide reliable insulation protection.

Grade 220 enameled polyurethane welding straight wire has high mechanical strength and wear resistance, allowing it to withstand the tension and pressure when winding wiring.

Class 220 enameled polyurethane welding straight wires are widely used in high-temperature motors, transformers, generators, welding equipment and other electrical equipment and instruments that require high-temperature insulation temperatures.

When using grade 220 enameled polyurethane welding straight wire, attention should be paid to its current load and temperature requirements to ensure that it is used within its rated temperature and current range, so as to give full play to its excellent heat resistance and insulation properties and ensure the reliability of power transmission. Safe and reliable.
