EHV Dry Compact Switchgear & Transformer Termination PHVS & PHVT for 72 kV, 145 kV and 245 kV

The dry compact switchgear termination for voltage classes up to 245 kV is designed to be installed in cable entry housings of gas-insulated switchgear (GIS). It complies with IEC 62271-209 standard, which essentially specifies the interfaces between the termination and the switchgear. Therefore the termination will fit into all GIS complying with IEC 62271-209. Adapters are available to match the dimensions of wet (oil-filled) type terminations, and older designs specified in IEC 60859. The termination operates in SF6 but also in insulating liquids like transformer oil.

• Dry interfaces, no oil-filling
• Dimensions comply with IEC 62271-209
• Pressure-tight resin housing
• Operates in SF6 and insulating liquids
• Pre-fabricated and factory tested Si-rubber stress cone
• Torque controlled or wedge-type multi-contact conductor bolt
• No special tools required to install the termination
• Isolated cable gland for sectionalisation
• Type tested according to IEC 60840, IEC 62067 and IEC 62271-209 standards

The joint is designed according to following standards:

• Type tested according to IEC60840, IEC 62067, IEEE404 & GB11017
• Manufactured according to ISO9001 and ISO14001
