Cable Types

We provide engineering services to support the use and maintenance of the following cable types:

Solid Cables with Extruded Polyolefin insulation:

XLPE, PE or EPR insulation.

Dry-type and wet-type constructions.

Self-Contained Cables (cables fully protected within their own metallic/polymeric sheaths):

Fluid filled* cables (self contained fluid filled - SCFF) with taped insulation with Paper, or PPL tapes, (*formerly termed low pressure oil-filled LPOF).

Pre-impregnated gas filled cables: with paper or PPL tapes.

Mass impregnated (MI) cables with paper or PPL tapes, draining and non-draining compound types (MIND).

Gas Compression Cables  (mass impregnated self-contained cores pulled into pre-laid steel pipes, these are indirectly gas pressurised via their flexible membrane sheath)

Pipe-Type Cables  (insulated cable cores pulled into pre-layed steel pipes and operated in direct contact with the pressurising medium)

High-pressure fluid filled (HPFF) with paper or PPL tapes

High-pressure gas filled (HPGF) with paper or PPL tapes

Gas Insulated Lines (metal busbar insulated with a pressurised dielectric gas and supported on spacers within a metallic pipe)

SF₆ gas

SF₆/N₂ gas mixture
