Polyurethane-enamelled round copper wire for straight soldering is a special type of enamelled wire with a polyurethane enamel layer, offering excellent straight soldering performance. The enamel layer of this round copper wire has good resistance to high temperatures, good electrical insulation and good mechanical strength, and can maintain good insulation and mechanical properties in a harsh working environment with high temperatures, high humidity and high pressure.



The main features of polyurethane-enamelled straight-soldered copper wire are as follows:
1) Good direct soldering: the lacquer layer of solderable polyurethane enamelled round copper wire has good direct soldering performance, enabling the circuit to be connected by direct soldering, avoiding the tedious process of etching and stripping traditional enamelled wire, and improving production efficiency.
2) Good high-temperature resistance: the lacquer layer of direct-solder polyurethane enamelled copper wire can maintain stable electrical insulation properties and mechanical strength in a high-temperature environment, and can withstand a higher temperature range.
3) Good electrical insulation performance: the enamel layer of direct-welded polyurethane-enamelled copper wire has good electrical insulation performance, preventing electrical leakage and arcing, and ensuring circuit safety and reliability.
4) High mechanical strength: the enamel layer of direct-welded polyurethane-enamelled copper wire has high mechanical strength, can withstand a certain degree of tension and pressure, and is not susceptible to fracture or deformation.
5) Good corrosion resistance: the lacquer coating on straight-welded polyurethane-enamelled copper wire has excellent corrosion resistance, and can maintain good insulation performance in corrosive gases, acids and alkalis, and other harsh environments.

Welded polyurethane-enamelled round copper wire is widely used in a variety of electrical equipment, especially in high-temperature, high-humidity, high-pressure and other harsh environments, such as motors, transformers, inductors, capacitors, etc.
