Cable Boxes

Cable boxes are available either as fully insulated using transformer oils, insulating compounds (G101), or Guroflex. Filled cable end boxes provide excellent electrical insulation to medium/high voltage cable terminations usually at 11kV/33kV. Unfilled HV cable boxes are used for dry termination of 11kV/33kV cables – 3 types of unfilled cable box are available:

Cable Boxes - Air Partially Insulated HV 11kV 33kV

1. Air Partially Insulated Cable Box – no additional MV-HV electrical insulation is required avoiding the need for additional site insulation works.

Cable Boxes - Heat Shrink Cable Terminations HV 11kV 33kV

2. Heat Shrink Cable Termination Box – fully insulated MV-HV cable boxes where the 11kV/33kV power cables are connected and terminated to the cable box bushings using heat shrink tubing insulation.

Cable Boxes - Plug In Separable Connectors HV 11kV 33kV

3. Plug-In Connector Cable Box – fully insulated using plug-in bushings for use with pluggable screened separable connectors, 11kV/33kV.


Available Cable Box Designs For High Voltage Cables
Supplied with self-colour aluminium gland plate complete with 6mm diameter pilot holes to aid gland fitting by others. If you are able to specify the glands you require these can be fitted in our workshops prior to delivery. If you require gland plate in Stainless Steel please add SS affix to Drawing Number i.e. C6005/SS.
