#cable terminations

T&D have an obligation to investigate any cable joint or cable termination product failure, but over the years we have been asked more and more to get involved in general cable failure analysis for high voltage HV networks.

undergo un-biased investigations into any failure involving high voltage cable joints and cable terminations regardless of manufacturers or whether heat shrink or cold shrink type.

Below are 5 case studies covering Cable Fault Analysis linked to the cable jointing and terminating of high voltage power cables. Click on the links for more information on each study.

Cable Termination Utilizing the Medium Voltage termination kits

Training Cable Termination Utilizing the Medium Voltage termination kits Solid dielectric power cable systems are subject to higher voltages than ever before. Inadequate installation and testing of cable splices and terminations is the number one cause of failure (IEEE Std 493-2007 Table 10-33). Yet over the last few decades, cable splicing as a profession has declined as multi-crafting and…

HV Heat Shrink Cable Joints & Cable Terminations. Fault Analysis

Nexans Medium Voltage Cable Accessories Book

A Theoretical & Practical Appraisal by Dr. Derek Goulsbra

Synopsis 

Cable accessories account for the least capital expenditure of a distribution network but can prove to be the weakest component of the system because they have to be assembled on site. This book examines the detailed workings of accessories and provides information to assist engineers and jointers who are responsible for specifying and installing medium voltage cable accessories.

Terminations, separable connectors, joints and associated equipment such as cable glands and cleats are examined in detail with explanations of the various technologies used. Great emphasis is placed on failure modes and methods of preventing potential problems in service.

By following the information presented, the reliability of accessories will be improved thus reducing the cost of expensive failures.

Nexans Power Accessories and cable terminations are for use on onshore and offshore wind turbines. In addition, Nexans range of inner cone and outer cone screened separable connectors for voltages up to 52kV, Nexans have developed a range of junctions with mounting frames and terminations chambers that utilise pre-terminated leads manufactured in-house by Nexans Power Accessories.
