Compact Substation 11kv Compact Substation Power Transformer Box Electricity Substation
Product Advantages
* Compact size
* Full Insulation Design
* Safe and reliable operation
* High Overload Capacity
* Superior performance and resistance to sudden short-circuit
* Convenient operation and reliable power supply
* Energy Saving, Low Loss
It is the first vehiclemounted movable substation in China. It has been sent to Iraq in Dec 2008. The product which has 132KV voltage class and 16000KVA capacity is completely researched & developed, designed and amnufactured by ourselves.
>> Divided into HV part,main transformer,LV switchgear Room.
>> HV Switch adopts ZF10-145(L) as main switch,barely mounted on a semi-trailer.
>> LV side switchgear,control power,DC panel and control protection device.
Technical feature:
1. Faster recovery of power
>> The prefabricated mobile substation is applied to fully or partial replace the conventional substation and resume the power supply in case of emergency.
2. Flexible solution
>> Help an area which suffers shortage of power supply capacity in heavy load season or period. Use as the temporary substation in areas with booming power demands that exceed the existing electric
power capability, to ease the tension of power supply.
3. Temporary solution
>> Work as a temporary substation in areas of permanent substation suspended due to the capital
shortage or other kind of reason.
4. Reliable solution
>> The prefabricated mobile substation is the flexible and reliable way for transportation with the
complete equipment. It also saves investment in various aspects, concerning the land requisition,
civil construction, equipment installation etc, which improves the reliability of power supply for the
system.
5. Higher efficiency
>> The prefabricated mobile substation provides with all the functions that a conventional substation
has, as well as easy installation and quick into the service. It could be into operation at once on site
after the connection of input and output cable only.
Our Advantage:
1. Various special requirement from customer or typical specification .
2. Competitive price (Real Factory).
3. Excellent quality control and faster feedback .
4. Good service and after sales.
5. In time delivery.
6. Manufacturing after drawings approved.
7. OEM is acceptable.We can change the design as client's requirements.
