HV-CONNEXCable Termination Systemsfor high voltage networks
Motivation: Dry TypeGIS / Transfomer compartment completely enclosed at
manufacturing site
Connection without expensive gas or oil works on-site
Quick Assembly
Works at the transformer and assembly of the cable termination are
completely independent

• Material Test
• Temperature Test (-40°C – 110°C)
• Rated Power Frequency Voltage (460kV)
• Partial Discharge (< 5pC at 2*U0)
• Gas Tightness (Helium; < 4*10-7 bar cm³/s)
• Pressure Test (2*design pressure 1min)
• X-Ray Test
Features of the Separable Connecting System
An interface for oil and gas insulated components
A complete connection system for cables, overhead lines and surge
arresters
Prefabricated and routine tested components
Quick and reliable assembly
Rapid and simple disconnection in the event of faults
Connection without expensive gas or oil works on-site
Works at the transformer and assembly of the cable termination are
independent of each other
