 Cast Resin 80kVA 100kVA 125kVA 35/0.4kV Power Transformer

1. Application

1). Our power transformers are especially suitable for installation in draw-out type or fixing type switchgears as well as for power plants, substation, self-consumption transformers, power distribution, transmitter system, earthing system, community power supply system, subway, or those places where small space, fire-control, moisture-proof, are needed. Those up to 10kV can be installed in 650 ~ 1200 mm wide switchgear, up to 20kV in a 1000mm wide switchgear and 35kV in 1400 ~ 1600 mm wide switchgear.

2).Our series reactors are suitable for a power system of 6~10kV.They are connected serially with high voltage parallel capacitor group to depress a wave deformation in the system. 

2.Technical Parameters

i) For Power Transformer:

1).Rated Primary Voltage: 6kV up to 35kV

2).Rated Secondary Voltage: 0.4kV

3).Rated Capacity: 3kVA up to 2500kVA

4).Rated Short-time P. F. Withstand Voltage (r.m.s.) (kV): 20, 25, 35, 50, 70

5).Rated Lightning Impulse Withstand Voltage (Peak) (kV): 60, 75, 125, 170

6).Phase No.: single phase or three phases

7).The Highest Temperature Rise of Windings: 100K

8).Insulation Class: F

9).Cooling Mode: AN or FN

10).Enclosure Protection: IP00, IP20 or custom specified

11).Connection Symbol: Yyn0, Dyn11or II0 or custom specified

12).HV Tapping Range (%): ±5 or ±2×2.5 

ii) For Series Reactor

2).Rated Capacity: up to 1200 kVar

3).Rated Current: up to 4000A

4).Rated Voltage For Capacitor (kV): 6.6√3, 7.2√3, 11√3, 12√3

5).Rated Frequency: 50Hz (60Hz on request)

6).Installation: indoor or outdoor

7).Series Reactor Number for Each Phase: 1

8).Insulation Class: F

*Except for the technical parameters list above, we can design as per clients’ requirements.

3. Main Features

1).Low loss, low noise, high operation efficiency
2).High ability of protection against short circuit

3).High mechanical strength  
4).Pre-galvanized steel frame, flame-resistant, against corrosion

5).With outstanding fire-proof capability: the epoxy resin is difficult to flame and self-extinguished. So it won’t lead to the second disasters, such as an explosion.

6).Cast epoxy resin with high dielectric strength 18~22kV/mm in vacuum process

7).Superior in environmental performance: the epoxy resin is very stable, moisture-proof and dust-proof. It enables dry-type power transformers to run with high reliability under abominable environment.

8) With theimpeccable temperature control and indicating system, dry-type power transformers can be maintenance free. And this offers a great reduction of operation cost.

9).With small volume, light and convenient for installation and alignment

10).No need of a separated room 

4. Materials

1).Insulation Material: epoxy resin

2).Winding Material: Aluminum wire or high quality enameled copper wire (foil winding is available for power transformer)

3).Core: core lamination, low loss, cold rolled grain oriented silicon steel 

5. Types of Our Reactors:

1).Dry-type Air Core Reactors, including: Dry-type Air Core Series Reactors, Dry-type Air Core Current Limiting Reactors and Dry-type Air Core Shunt Reactors.

2).Core-type Reactors, including: Core-type Series Reactors, Core-type Start-up Reactors, Core-type Shunt Reactors, Arc Suppression Coils, Core-type Earthing Transformer and Filter Reactors and so on. 

6. Manufacturing Standard

1) Power transformer: IEC60076-11:2004, GB1094.11-2007, GB/T10228-2008

2) Series reactor: IEC60076-6:2007, GB/T 1094.6-201 

7. The products are especially suitable for installation in draw-out type or fixing type switchgears as well as for power plants or substation self-consumption transformers or those places where small space, fire-control, moisture-proof, are needed. Those up to 10kV can be installed in a 650~1200mm wide switchgear, up to 20kV in a 1000mm wide switchgear and 35kV in a 1400~1600mm wide switchgear.
