Product Description

High Voltage Link Box for up to 145kV
 

                                  JDX Earthing Boxes                                                        JDBX Earthing Boxes with BHQ                                                       JCHX Cross-link Boxes

Single 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.

JDX, JDBX Earthing Boxes
JDX and JDBX link Boxes are used for earthing the metallic cable sheath of single core cables up to 145kV. The JDX Boxes are earthing directory, the JDBX are designed with sheath voltage limiters. Both JDX and JDBX boxes are designed with perfect sealing property.

JCHX Cross-link Boxes
JCHX link Boxes are used for earthing and bonding cable sheaths of single core cables up to 145kV, so that the induced voltages and circulating currents are eliminated or reduced, which will increase the transmission capacity and reduce the heating of the cable. JCHX boxes are designed with perfect sealing property.

BHQ sheath voltage limiters
The optional sheath voltage limiters BHQ are made of zinc oxide and designed to provide active over-voltage protection that contributes directly to improved reliability of the system. The JDBX and JCHX link boxes are designed with BHQ.
