The installation of the heat shrinkable cable accessories must be a complete continuous construction, so as not to be affected with damp be affected with damp, 10 kv and below cable heat appears should be completed within four hours. C .
Type heat shrinkable power cable accessories has small volume, reliable performance, strong adaptability,
simple and easy for installation.
Applicable to power cable households inside and outside the terminal and intermediate links.
The end of the insulation tube is generally 650mm, but can also be extended to
800mm, 1000mm, 1200m.(according to the requirements of customers).
Before making cable head, need special tools to be complete, construction personnel
should be familiar with the use of various instruments, inspection, and matters needing attention.
The steel armor ground wire and copper screen ground wire separately,
making the cable pre-test more convenient and reasonable.
