Dry compact switchgear/transformer terminationGeneral Description

TE’s Raychem PHVS dry compact switchgear termination for voltage classes up to 230 kV is designed to be installed in cable entry housings of gas-insulated switchgear (GIS). It complies with IEC 62271-209 or IEC60859, which essentially specify the interfaces between the termination and the switchgear. Adapters are available to match the dimensions of wet (oil-filled) type terminations. A corona shield at the top of the termination then provides the necessary shielding of the terminal if operating in insulating liquilds like transformer oil. The termination is easily separable and consists of a plug-in part and an epoxy resin insulator, which can be pre-installed separately in GIS or transformer and cable manufacturer to save installation time on-site and reducing the risk of contamination of the cable entry housing.

Features & Benefits

• Dry interfaces, no oil-filling• Dimensions comply with pressure-tight resin housing• Pre-fabricated and factory tested silicone rubber stress cone• Torque-controlled multi-contact conductor bolt• No special tools required to install the termination• Isolated cable gland for sectionalization• Solderless grounding connection ensures the effective currency but avoids the heat

damage on the cable insulation• Type tested according to IEC60840 & GB/T11017, IEC62067 & GB/Z18890
