Summary
XGN36-12(DXG-12)switchgear is a new miniaturization power networkequipment which introduced advanced technology and combine with ourcompany real condition.With excellence of high grade,complete parameter,low price,few maintenance.It applies to 3.6~12KV three phase AC50/60Hzsingle busbar or busbar sectional system for receving and distribution powerenergy.It can widely used for electric power,metallurgy petifaction and urbanconstruction.
Ambient condition
- Ambient temperature: -10℃ ~+40℃；
- Altitude: ≤1000m；
- Relative humidity: daily average ≤ 95%, monthly average ≤ 90%;
- Earthquake intensity:≤ 8 degree;
- Applicable occasions should be free from inflammable, explosives and severe vibration.
Model
Product feature
1. The panel is novel and complete function, not only with fixed panel isolate live busbar feature, but also convenient for maintenance, easily to exchange circuit breaker, thereby assure of maintaining safely and conveniently, meanwhile, choose primary plug in contact.
2. Main switch is miniaturization vacuum circuit breaker(introduce advanced technology). Choose large creeping distance porcelain enclosure vacuum arc extinction chamber, adopt air insulation. It suitable for rural net work reconstruction and industrial enterprise specially, equipped with miniaturization disconnect switch, double functions for main knife switch and earthing switch,gear drive type.
3. Panel is combination type, without welding, without deformation, miniaturization volume. With reliable “five protection” interlock function, compulsive mechanical interlock on rear and front door.
