Link boxes are used with cable joints and terminations to provide easy access to shield breaks for test purposes and to limit voltage building up on the sheath. Lightning, fault currents and switching operations can cause over voltages on the cable sheath. The link box optimizes loss management in the cable shield on cables grounded from both sides.
