Notes to the ordering of the box type Prefabricated substation

1. High voltage

Way of incoming line: terminal type, looped network type or double power in.

With the high pressure measurement or not. The position of the measurement(front of the switch or behind the switch), the requirement of the meter gauge and its supplier.

Type of the HV switch, one way is using the high voltage vacuum load switch and the fuse-combination unit which is the mainly used and its price is more economical; the other is adopting the disconnector switch and the vacuum breaker which is used in the high capacity transformer with higher price.

2. Transformer

The transformer type, serial-number, the connection symbol group, capacity and the impedance voltage of the transformer.

3. Low voltage

Grade of the switch(Supplier).

The number of the outlet and the rated current value of every outlet switch.

With the compensation or not, and the capacity of the compensation.

With the measurement or not and the position.

4. Type of the busbar (copper or aluminum)

5. Layout of the transformer substation(with the operation corridor or not)

6. The material of transformer shell: composite board (commonly used), steel plate, stainless board or cement.

7. Delivery Period for European-type prefabricated substation
