Development of cold shrinking tube-type indoor termination and straight joint (MINICONE QUICK series) for 6600V XLPE cable

摘要

Taping-type, insertion-type and heat shrinking tube-type termination and joint have been used extensively for 6600V XLPE cable. However, these types all have problems like lacking safety due to the use of fire or requiring certain skills for the assembling work. The cold shrinking tube-type indoor termination and straight joint for 6600V XLPE cable were developed to improve these problems. The assembling work of the developed termination and joint is very easy in comparison with the usual type, the number of parts were decreased, and the size was reduced. Sufficient long-term reliability has been confirmed by the success of development tests.
