8DJH Modular design
- Individualpanels and panel blocks can be lined up and extended at will – without gas work on site
- Low-voltage compartment available in 4 overallheights, wiring to the panel via plug connectors.
Panel design
- Factory-assembled, type-tested
- Metal-enclosed, with metallic partitions1)
- Hermetically tight, welded switchgear vesselmade of stainless steel
- Maintenance-free
- Degree ofprotection
– IP 65 for all high-voltage parts of the primary circuit in the gas-insulated panels
– IP 2X for the switchgear enclosure
- Vacuum circuit-breaker with three-position disconnectorfor disconnecting and earthing
- Three-position switch-disconnector
- Cable connection with outside-coneplug-in system according to DIN EN 50181
- Wall-standing arrangement, optionally free-standingarrangement
- Installation andpossible later extension of existing panels without gas work
- Replacement of instrument transformers without gas work, as they are located outside the gas compartments
- Enclosuremade of sendzimir-galvanized sheet steel, front cover powder -coated in color “light basic” (SN 700)
- Low-voltage compartmentremovable, plug-in bus wires
- Lateral,metallic wiring ducts for control cables.
Instrument transformers
