As a typical F-class heat-resistant enameled wire, this 155℃ Grade 2 product can maintain stable mechanical properties and insulation performance under continuous long-term operation at 155℃. Its insulation coating is made of modified polyurethane or polyester composite material, which has been optimized through cross-linking treatment. Even under the condition of frequent motor start-stop and instantaneous temperature rise, it will not suffer from insulation aging brittleness or coating falling off. After strict testing, the product can withstand 200 hours of continuous thermal aging at 175℃, and still maintain more than 80% of the original breakdown voltage performance, far exceeding the basic requirements of the standard. It can adapt to the harsh operating conditions of various heavy-load motors in metallurgy, mining, chemical industry and other fields, effectively extending the service life after motor rewinding.
Full Compliance for Motor Rewinding Scenarios
This series of enameled copper wire is designed to perfectly match the actual needs of motor rewinding work. It has excellent winding performance, the coating has moderate friction coefficient, no paint peeling or scratching during manual or semi-automatic winding, and it has strong adhesion after being embedded in the slot, which will not be damaged during the subsequent slot extrusion process. The product has a breakdown voltage of more than 3000V, and the pinhole defect rate per 5 meters is less than 1, which can effectively avoid hidden dangers of turn-to-turn short circuit after motor rewinding. The Chinese manufacturer strictly controls the production process, and each batch of products is equipped with a complete test report, which can be directly traced to the production date and process parameters, providing reliable quality support for motor maintenance teams.
Stable Supply and Global Service
Relying on the complete industrial chain advantage of China’s copper deep processing industry, this 0.5-3.0mm 155℃ Grade 2 enameled copper wire can achieve stable mass supply, with conventional specifications in stock all year round, and the delivery cycle can be as fast as 2-7 working days. The manufacturer can also provide customized services according to the special needs of users, including special packaging, fixed-length cutting, etc., to meet the differentiated needs of different motor rewinding scenarios. At present, this product has been exported to many regions around the world, and has become the preferred rewinding material for a large number of local motor maintenance enterprises with its stable quality and competitive price.
