Self Contained Fluid Filled
Self Contained Fluid Filled (SCFF) cable systems, also known as Low Pressure Oil Filled (LPOF) consist of cables, joints and terminations with oil-impregnated paper dielectric insulation. This is a legacy technology which was the norm for high voltage cable insulation during most of the 20th century. There is still a significant number of SCFF cable systems in service which need to be maintained, repaired, upgraded, diverted, and eventually de-commissioned and removed.
EHV Power provides the following services for SCFF cable systems:
- Hydraulic system analysis and rehabilitation
- Dieletric fluid degassification and testing
- Installation of SCFF cable terminations up to 345kV
- Installation of transition SCFF to XLPE cable joints
- Dissolved gas analysis reporting
- Installation of sheath bonding systems
- Fault locating
EHV Power can service any brand of SCFF cable and accessories, with special focus on Canada Wire & Cable (CW&C), Alcatel Canada Wire (ACW) and hvGrid-tech systems.

Overview
EHV Power can provide a full
range of design, installation
and maintenance services.
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.
