Product Description

Czbt1-132kv 132kv/11.5KV movable Mobile power transofrmer substation

Outdoor,dust and water proof (132/11.5)kv,25mva Mobile substation according to IEC standard .
The Mobile substation consists of two trailer(A&B).

Trailer (A) Carries the following equipments:
* Three pcs lighting arrester of (120kv,10ka) .
*3-phase,two-pole,vertical break(145kv,630A,31.5KA/1SEC).disconnected switch with earth switch at transformer side.
*3-phase,vacuum circuit breaker(145kv,630a,31.5KA/1SEC).with spring operating mechanism.
*One,3-phase(132kv/11.5kv)25mva YND11 oil immersed power transformer with (17) steps on load tap changer(OLTC) at high voltage side with regulatio( ±10% of 132kv).
*One pcs lighting arrester of (75kv,10ka)at neutral point of 25mva power transformer.
*One,3-phase,75kva,11.5kv/380v-220v,znyn1,auxiliary&earthing transformer with neutral current 300A/10SEC.
*Safety fence.
*All current transformers for 132kv side and neutral point are bushing types.
Trailer (B) Carry the following equipments:
One cabinet dust and water proof contain the control panel,protection panel,A,C distribution board,metering and energy board and equipped with suitable air condition.
One cabinet contain the 12kv,air-insulation metal-enclosed switchgear the switchgear consists of (one panel for 12kv voltage transformer with surge arrester,one panel for 12kv incoming feeder,five panels for out going feeders).

One Cabinet contain 110V,D.C system( charger,battery and D.C distribution board) with suitable ventilation

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.
