People Electric · Metal-Enclosed Switchgear
Product overview
People Electric KYN61-40.5 metal-clad withdrawable switchgear is intended for three-phase 50Hz, 40.5kV single-bus and sectionalised single-bus distribution systems. The source describes separate functional compartments and interlocks, with several breaker and circuit arrangements. Select the complete project design and verify the actual environmental enclosure; no weatherproof installation claim is inferred from the webpage name.
Technical selection summary
| Manufacturer / system | Original People Electric KYN61-40.5 |
|---|---|
| Rated voltage / frequency | 40.5kV; AC50Hz |
| Main busbar current choices in cabinet table | 1250 / 1600 / 2000A; exact design confirmation required |
| Branch busbar current choices | 630 / 1250 / 1600A; not interchangeable with main-bus ratings |
| Power-frequency withstand voltage | 95kV for1 minute, phase-to-phase and phase-to-earth; 115kV across primary isolating gap |
| Lightning impulse withstand voltage | 185kV phase-to-phase and phase-to-earth; 215kV across primary isolating gap |
| Auxiliary control circuit withstand | 2000V for1 minute |
| Short-circuit breaking ratings listed | 25 / 31.5kA, subject to exact breaker and complete assembly |
| Making / peak withstand ratings listed | 63 / 80kA, subject to selected design |
| Short-time withstand ratings listed | 25 / 31.5kA for4s; verify pairing with selected circuit components |
| Compartment protection | IP2X between compartments and when the breaker-compartment door is open; this does not establish the closed enclosure weather rating |
| Environmental conditions in introduction | Altitude ≤2000m; ambient −15 to +40°C; daily average humidity ≤95%, monthly average ≤90%; no severe contamination, corrosive atmosphere, explosion hazard or severe vibration |
| Outline and control supply | Approve the exact dimensional drawing and control-voltage specification; incomplete general-table entries are not extrapolated. |
| Component choices described | ZN85-40.5 vacuum breaker and SF1/SF2 or FP-series alternatives. Confirm exact devices and circuit duties. |
| Standard references | IEC60298, GB3906 and DL404 in original source; complete-assembly conformity and test evidence require confirmation. |
Catalogue current and fault-rating alternatives are not a verified Cartesian product. Quote against approved circuit, breaker and cabinet drawings. The webpage name contains an outdoor descriptor but the provided general data does not establish a closed-enclosure weather rating; confirm the actual installation and enclosure design before purchase.
Typical applications
