I-FN12-12 Series Indoor High Voltage Air Load Break Switch

Imininingwane Yomkhiqizo

I-FN12-12 ye-HV air load break switch iyisisetshenziswa se-AC 50Hz 12kV esinezigaba ezi-3.

♦ Indlela yokufaka: ifakwe ngaphambili, ifakwe ohlangothini, ifakwe phezulu;

♦ Indlela yokusebenza: indlela yokusebenza yasentwasahlobo, uhlobo lwezandla kanye nohlobo lukagesi olutholakalayo;

♦ Uhlobo lokusebenza: ukusebenza kwesokudla kanye nokusebenza kwesokunxele;

♦ Isicelo: i-switchgear engu-12kv yangaphakathi.

Izimo Zemvelo

♦ Izinga lokushisa lendawo: -25°C~+40°C;

♦ Ukuphakama:

♦ Umswakama ohlobene: isilinganiso sansuku zonke esingu-

♦ Amandla okuzamazama komhlaba:

♦ Ibanga lokungcola: II;

♦ Izindawo ezingenamlilo, ukuqhuma, ukugqwala kwamakhemikhali kanye nokudlidliza okukhulu.
