We have completed the re-adjustment of the entire product system and operation system to better provide quality Energy Saving Oil Filled Transformer, prefabricated electrical substation, 12/24kV vacuum circuit breakers and services. Before the establishment of our company, we had a thorough understanding of the industry in recent years and participated in the actual operation of some brands. When we look to our purpose and values to inform our judgment, our decisions will always have integrity. We always insist on strengthening scientific and technological innovation as the starting point of the market. From the moment of establishment, we have been committed to creating value for our customers and regard it as the highest service standard.

The 20kV box type prefabricated substation is a compact complete set of power distribution equipment in one or several boxes, which is composed of high voltage switchgear distribution transformer, low voltage switchgear, electric energy metering equipment, reactive power compensation device, integrated automation system, communication, remote operation, metering, capacitor compensation, dc power supply and other electrical units. Widely used in urban power grid transformation, residential areas, high-rise buildings, mining, hotels, shopping malls, airports, railways, oil fields, ports, highways and temporary power facilities and other indoor and outdoor places.

Specification:

1.Rated voltage:20kV

2.Maximum operating voltage:24kV

2.The utility model has the advantages of flexible combination,convenient transportation, migration and installation,short construction period, low operation cost, pollution-free and maintenance free,etc.

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
