电缆导体感应加热原理及其应用

Principle of the induction heating of cable conductor and its application

本文简要介绍了高频磁场感应加热的原理、特点,以及在电缆制造中导体预热的应用,这可提高电缆产品的质量,减小电缆绝缘层的内应力,使绝缘与导体更良好的结合,从而延长了电缆的使用寿命,另外,还可改善绝缘的交联效果,提高生产线速度,从而提高生产效率。

This paper presents briefly the principle,characteristic,and the application in the pre-heating of conductors during cable production of the induction heating by HF magnetic field.This method may improve the quality of the cable product and reduce the internal stress of the insulation so that a better fitting between the insulation and conductor is realized.In this way,the cable service life may be lengthened,the cross-linking effect of the insulation may be improved,the line speed may be raised and the productivity may be increased.
