Raychem High Voltage Outdoor Terminationup to 245 kV

Powering the UKCable Services Limited

The Raychem OHVT SystemThe high voltage outdoor termination(OHVT) is designed for voltage up to245 kV and to operate under severeenvironmental conditions.Polymeric insulated cables of variousdesigns can be adopted with respect toshielding and metal sheath. Compositeor porcelain housings with differentcreepage lengths are available coveringthe most common and also extremepollution levels. The installation of thetermination can be done by trainedinstaller equiped with conventional tools.

The termination is designed accordingto following standards: IEC-60840,IEC-60815, IEEE-48; IEEE-1313

Cable lugThe cable lug is suitable for all commoncondutors made of aluminium orcopper.

Sealing systemThe flexible double sealing system isinstaller-friendly and ensures permanentprotection against environmentalinfluences of the top assembly.Heat-shrinkable polymeric tubecontaining oil-resistant sealantencapsulates the connector barreland the polymeric insulation transition.

Insulator housing and oil-fillingThe pressure-tight composite housingis made of a glass fibre reinforced (GFR)resin tube with silicone rubber shedsmoulded to the tube.The interface between stress cone, cable insulation and inner housing will be filled from the top with silicone oil. No prior heating of silicone oil required.

Stress coneThe silicone rubber stress cone providesthe electrical field control function andcan easily be applied without tools. Theapplication range is taken by differentsizes of stress cones.

Base plate and support insulators4 support insulators can be used on thebase plate to mount the terminationinsulated. The termination can bemounted direct on the supportstructure as well. All metallic fittingsare made of corrosion resistant Al alloy.

Gland and sealThe cable gland outer serving isadapted through different gland sizes,which can serve the individual shieldingand armouring of the cable.The heat-shrinkable tube provides theouter protection and sealing for thecable gland area.
