Applicable to emergency cable repair and in-house production.
maintenance free joint' is a technology for power cable restoration which can be applied in the cable laying field. The essence of the MFJ is to provide a highly secure, reliable and stable joint technology for cable system by silver brazing and crosslinking control method to ensure that the performance of joint is the same as original cable. This technology thoroughly solves the fundamental problems of the active interface caused by connection between cable accessories and cable. So, this joint has a good mechanical and sealing performance, which can not easily affected by moisture or heating up , resulting in a low fault rate, The distribution of electric field in this joint is the same as the original cable.
