Box Type Transformer Substations - China

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.

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.
