24kV SF6-gasisolierte Schaltanlagen 101217

ELE-24 Series SF6 gas insulated switchgear introduce SF6 as insulator and arc-extinguishing medium, it spread at an pressure of 0.02 0.03MPa in a stainless steel tank, in which the primary live parts, the busbar and switch contacts are kept. The bushing interface design is via standardized outer cone bushings to EN50180/50181(DIN47636), which connect the cables via insulated and shielded separable connectors. Because the structure is compact, and free from environmental variation, it specially applies to an adverse zone of great temperature difference, dewdrop, contaminant, small animals and chemical substance etc. 1 min. Rated Power Frequency withstand Voltage: To earth & between phase: 65kV/1min. Across the isolating distance: 79kV/1min., Impulse voltage 125kV/145kV. Apply to dead earthed neutral system.
