ZGS COMBINED TYPE TRANSFORMER SUBSTATION
ZGS11 combined type transformer substation is more compact than the YBM type substation. It follows American design and uses compact low voltage switches to reduce volume, thus to lower the cost.
Installation conditions
1. Ambient air temperature: -25°C ~ +40°C;
2. Relative humidity ≤ 95% (+25℃)
3. Altitude ≤1000m;
4. Wind speed ≤ 35m/s;
5. Horizontal acceleration ≤ 0.4m/s2, Vertical acceleration≤ 0.2m/s2;
6. Installation places should without conductive dust, corrosive nor explosion gas. No violent vibration, vertical gradient<3o.
If the switchgear will be used in conditions that exceed the normal environmental conditions, please consult with us.
Application
ZGSCombined type transformer substation is reliable power supply.It is very compact and low cost, easy for installation, operation and maintains. It’s widely used in industrial park, high buildings, residential district, labor, wharf, airport, hotel, business center, etc.

The low voltage cabinet is specially equipped with intelligent under voltage controller, which has the function of identifying the abnormal voltage of the low voltage busbar of the substation, and can also avoid the tripping function of the low voltage switch caused by the trip of the 10kV high voltage line or during power outage maintenance.
