Current and voltage transformers can be added and the standard SF6 to air bushings can be replaced with cable connectors. Its modular design allows for a large variety of different layout configurations and enables a more economical substation design.
GE Vernova Advantage
HYpact assembly enables more economical substation design and operation, with savings to be achieved in space consumption, preparation planning, transport and at-site installation, switchyard cost and maintenance. Operators also choose HYpact where space is ample to benefit from the long maintenance periods. Compared to conventional air insulated substations, the maintenance-free periods of substations using HYpact can be tripled or even quadrupled.
In addition to savings in space and maintenance, HYpact largely reduces the switchgear’s exposure to environmental influences, thus providing an economic alternative to gas-insulated substations in places being heavily polluted, or under extreme weather conditions.
Key Features
The HYpact hybrid compact switchgear assembly is uniquely suited for a variety of situations, including space constrained installations and use in polluted or seismic environments. In addition, it also qualifies for mobile applications, either installed on trailers or on skids.
Due to the low number of bushings and the avoidance of movable contacts, pure SF6 gas Hypact units perform well in harsh climates, even under heavy snow and ice load, or at temperatures as low as -60°C (GOST FK certification).
