TB31QT20 is an indoor Medium Voltage Termination for single-core extruded radial electric field cables with voltage 12/20 - 24 kV.
The insulator of the TB31QT20 consists of a single insulating body made of smooth anti-trace silicone rubber expanded on a spiral. The insulator also incorporates the electric field control element. Shrinkage is accomplished cold, without the use of equipment, by unwinding the spiral.
The package contains all the materials for making three single-pole terminations.
