ENSTO end and connection couplings for medium voltage are also based on the use of heat shrinkage technology.
ENSTO cold shrink couplings are distinguished not only by their ease of installation and breadth of application, but also by a unique electric field equalization system.

The semi-conductive shield is restored by a stress control tube, which is easy to install and provides high reliability and efficiency against damage in this most vulnerable part of the connection (termination).
The stress control tube smoothes and equalizes the electric field surge at the boundary of the insulation-semiconductor layer transition.
