Cross Bonding & Sectionalisation for HV Cable Systems
Link boxes are used with cable joints and terminations to provide easy access to shield breaks for test purposes and to limit voltage build-up on the sheath. Lightning, fault currents and switching operations can cause overvoltages on the cable sheath. The link box optimises loss management in the cable shield on cables grounded both sides.
