10.7 Dimensions of three-core cables

The most important dimensions of indoor sealing ends for three-core cables are the permissible length and
diameter of the sealing ends, as well as the length of the cable lug up to and including the heat-shrinkable
splitting cap.
The bolts for the cable sealing ends are already pre-assembled at the cable connection and must not be
changed.
