Chidziwitso cha malonda:

FZW28-12F panja poyika malire a vacuum load switch (yomwe imatchedwa kusintha kwa malire) imagwiritsidwa ntchito pokhazikitsa ndime zakunja, ndi ntchito yamanja ndi yamagetsi. Gulu losinthira limatenga ukadaulo wa VSP5-12 wotumizidwa kuchokera ku Toshiba Corporation yaku Japan. Kusinthaku ndikusintha kopanda kukonza. Kugwiritsa ntchito vacuum extermination ndi SF6 gasi ngati njira yotetezera pansi ndi gawo. Chogulitsachi chikugwirizana ndi: G83804 (High Voltage AC Load Switch) ndi GBT11022 "Zofunika Zazonse Zaumisiri pa High Voltage Switchgear ndi Control Equipment Standards". FZW28-12F yakunja yotchingira vacuum load switch ili ndi ntchito yozindikira zolakwika, ntchito yoyang'anira chitetezo ndi ntchito yolumikizirana, yoyikidwa pa 10kV Pamizere yakumtunda, imatha kuzindikira kuchotseratu zolakwika za gawo limodzi ndikudzipatula kwakanthawi kochepa pakati pa magawo. Malo oyikapo ndi oyenera kuyika malire a mzere wofikira wa 10kV wa wogwiritsa ntchito; ingagwiritsidwenso ntchito ku kugwirizana kwa mzere wa nthambi womwe umakwaniritsa zofunikira.

Zoyenera kugwiritsa ntchito:
Kutentha kwapakati: osapitirira +40ºC, osatsika kuposa -15ºC;
mpweya wachibale chinyezi: pafupifupi tsiku ndi tsiku si oposa 95%, ndipo pafupifupi pamwezi si kupitirira 90%;
Kutalika sikudutsa mamita 1000;
Kuchuluka kwa chivomerezi sikudutsa 8;
Malo opanda moto, kuphulika, kuipitsidwa kwambiri, kuwonongeka kwa mankhwala ndi kugwedezeka kwakukulu.
