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

Routine Tests

• Routine Test according to (EN50089 / DIN

EN 60137 / DIN EN 62271-203 / DIN EN

50089)

• Visual Examination

• Meausurements

• 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
