TE Connectivity Raychem Link Boxes

For earthing and bonding cable sheaths of single core cables

Link Boxes

high voltage cable jointSingle core cables in operation carry alternating currents and induced voltages in the metallic sheath of the cable. These currents may cause, depending from the sheath bonding, circulating currents flowing in the cable sheath which reduce the transmission capacity of the cable and cause an additional heating. Link Boxes are used for earthing and bonding cable sheaths of single core cables so that the induced voltages and circulating currents are eliminated or reduced.
