CCC与UL三重绝缘线认证的差异
Differences between CCC and UL Certification on Triple Insulated
Wire
摘要 从使用范围、线径、结构和测试方面对比分析GB 4943-2001附录U和UL 2353:2004中的三重绝缘线,重点比较了结构部分的导体尺寸、层数和绝缘厚度,以及测试部分的抗电强度测试、柔韧性和附着力测试、热冲击测试、弯曲后抗电强度的保持和红外分析测试。
关键词 三重绝缘线;附录U;UL 2353;结构;测试
Abstract This paper analyses the differences between Annex U(GB 4943-2001)and UL
2353 through application range, wire diameter, construction and tests. The paper
focuses both on the construction such as conductor dimensions, number of layers and
insulation thickness, and on the tests such as electric strength test, flexibility and
adherence test, heat shock test, retention of electric strength after bending test and
infrared analysis test.
Keywords triple insulated wire; annex U; UL 2353; construction; test
