Uhlaka

I-FN7-24(DR) Iswishi yekhefu ye-HV yasendlini isebenza ohlelweni lukagesi olunogesi olinganiselwe ongu-24kV kanye nezigaba ezintathu ze-AC 50/60Hz, zokuxhuma nokuphula umthwalo wamanje kanye nomjikelezo omfushane wamanje.

Sebenzisa Izimo

A. Ukuphakama: ≤1000m.

B. Izinga lokushisa le-ambient: -25℃~+40℃.

C. Umswakama ohlobene: isilinganiso sansuku zonke ≤95%, isilinganiso sanyanga zonke ≤90%.

D. Akukho ukudlidliza okukhulu okuvamile.
