| Brand | Switchgear parts |
| Numero sa Modelo | 12KV ka mga environmentally friendly nga (air insulated SF6 gas free, nitrogen filled) isolation switch |
| Naka nga boltahang rated | 12kV |
| Rated Current | 630A |
| Serye | GHK |
Ang GHK-12 PT isolation switch gigamit og usa og usa sa integrated spindle structure, nga may adunay mga abilidad sama sa uniform electric field, maayo nga synchronization, kaugalingon nga serbisyo nga agad, walay pangangailangan sa maintenance, ug sayon nga pag-install. Kini nga produkto gilaoman gamiton sa environmentally friendly air insulated ring main unit cabinets isip primary nga komponente sa PT unit cabinets, responsable sa mga function sama sa PT main circuit closing, opening, ug grounding.
Environmental conditions for use:
1) Environmental temperature: maximum temperature+40 ℃, minimum temperature -15 ℃ (storage and transportation allowed at -30 ℃);
2) Altitude: ≤ 2000 meters;
3) Environmental humidity: Daily average relative humidity ≤ 95%, monthly average relative humidity ≤ 90%;
4) Seismic intensity: not exceeding 8 degrees;
5) Location of use: No flammable or explosive hazards, no water vaporization, corrosive gases, or severe vibrations;
Para sa mga espesyal nga sitwasyon nga wala magkita sa normal nga operating conditions, ang user sa produkto kailangan mobangon sa kasabutan sa manufacturer. Tumong, kon ang electrical equipment iginstall sa altitude nga mas taas pa sa 2000 meters, kinahanglan naa'y special instructions aron mapag-uli sa manufacturer ang produkto samtang nag produce.
