POWER TUNNELS

High voltage cable systems are often installed inside tunnels and shafts, such as in urban centres, hydroelectric generating stations, among others. Installing and servicing high voltage cable systems in this kind of confined and challenging environment requires specialized manpower, equipment and know-how.

SELF CONTAINED FLUID FILLED (SCFF)/LOW PRESSURE OIL FILLED (LPOF)

Also known as Low Pressure Oil Filled (LPOF) consist of cables, joints and terminations with oil-impregnated paper dielectric insulation.

HIGH PRESSURE FLUID FILLED (HPFF)/HIGH PRESSURE PIPE TYPE (HPPT)

Consist of paper insulated cables encased in steel pipes and filled with dielectric oil maintained at high pressure (typically 200-300 psi).

CROSS-LINKED POLYETHYLENE SOLID DIELECTRIC
(XLPE)

Solid dielectric insulation technologies were developed during the latter part of the 20th century, as an alternative to paper/oil insulation for cable systems.
