Have a look at a sample of our project history.
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.
POWER
TUNNELS
High voltage cable systems are often installed inside tunnels and shafts, such as in urban centres, hydroelectric generating stations, among others.
