Southwire offers an array of sheath grounding link boxes to complete the desired sheath grounding arrangement. Link boxes are used in combination with terminations and splices to limit cable sheath voltage rise. 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 on both sides.
