ZBW box-type substation (10KV)
ZBW modular substation series are designed to combine high-voltage electrical equipment, transformers, low-voltage electrical equipment into a compact package of power distribution devices commonly known as the European box-type substation. The products are suitable for 10KV (6KV) AC 50Hz substations, which are the distribution devices that combine high-voltage switchgear, transformers, and low-voltage switchgear, featured by small footprint, simple installation, safe and reliable performances, easy maintenance and other advantages. They can be directly connected to loads. One-time installation is enough to achieve the power transmission purposes. The combination of multiple units can constitute different power supply modes; therefore, the products are widely used in residential areas, high-rise buildings, tourist attractions, highways, industrial and mining enterprises, oil terminals, rural and rural networks and other places.
Environmental Conditions for Operation
1. Altitude: ≤ 1000m.
2. Wind speed: ≤ 34m / s (not more than 700Pa).
3. Ambient temperature: highest temperature +40 ℃, lowest temperature -35 ℃.
4. Relative humidity: daily average value of not more than 95%, monthly average value of not more than 95%.
5. Shockproof: horizontal acceleration not greater than 0.4m / s2, vertical acceleration of 0.15m / s2.
6. Installation site inclination: not more than 3 °.
7. Installed in places away from fire or explosion hazards, serious contamination, chemical corrosion and severe vibrations.

Product Features:
1. Good completeness, small size, compact size, safe and reliable operation, easy maintenance, and removability, etc.
2. Compact structure, small size, covering an area of only about 3.5 m2, greatly reducing the construction costs.
3. As the high-voltage control and protection electrical equipment is inside the transformer box, without live exposed parts, the operations are safe and reliable. The energy-saving transformers have excellent performance, and goodenergy-saving effect.
4. Because the cooling surface of the transformer is in the natural cooling state outdoors, with heat dissipation conditions, the capacity of general box-type transformers is up to 1600kVA or less.
5. The substation structure adopts a “mu” shaped or “triangle” shaped layout.
6. The housing is made of aluminum alloy plate, stainless steel plate, composite board, or glass fiber reinforced cement board, and can be produced according to the need of the user.
7. Substation base is made of galvanized steel or cement, resistant to corrosion, with sufficient mechanical strength.
8. The roof has a double-layer structure, with good insulation, anti-radiationand ventilation effects.
9. The rooms of the substation are separate chambers partitioned with iron plates; all the rooms are equipped with lighting facilities. The top of the transformer rooms are equipped with automatic exhaust devices to adjust the transformer room temperature.
10. The colors of the housings are flexible, to be coordinated with the surrounding environment.
