Description

33kV 100kVA 400kVA 500kVA 630kVA 3 Phase Oil Immersed Power Distribution Transformer

The C.DIVINE 33kV Three Phase Oil Immersed Power Distribution Transformer is designed to provide dependable voltage transformation for medium-voltage electrical distribution systems.

Available in 100kVA, 400kVA, 500kVA and 630kVA ratings, the transformer range provides different capacity options for commercial buildings, industrial facilities, residential estates, private substations and infrastructure projects.

A transformer receives electrical energy at one voltage level and transfers it to another voltage level through electromagnetic induction. For a typical 33kV distribution application, the transformer receives medium-voltage electrical power and steps it down to the required low-voltage distribution level.

The exact secondary voltage, winding configuration and other technical characteristics should be specified according to the electrical network and project design.

Available 33kV Transformer Capacities

The appropriate transformer capacity should be selected using a professional electrical load calculation rather than simply choosing the largest available rating.

33kV Three Phase Oil Immersed Transformer

The 33kV three-phase transformer is intended for medium-voltage electrical distribution networks.

Its three-phase configuration makes it suitable for electrical systems supplying three-phase loads such as:

• Industrial machinery
• Motors
• Pumps
• HVAC systems
• Manufacturing equipment
• Commercial building services
• Lighting systems
• Distribution boards
• Industrial production equipment

The transformer can form part of a complete electrical substation together with high-voltage switchgear, protection equipment, surge arresters, cables, metering equipment and earthing systems.

Oil Immersed Power Transformer

The C.DIVINE transformer uses an oil immersed construction, where the transformer’s active components operate within insulating transformer oil.

The transformer oil provides two important functions:

Electrical Insulation

The insulating oil helps separate energized internal components and provides electrical insulation within the transformer.

Heat Transfer

Electrical losses within the transformer generate heat. The oil transfers heat away from the core and windings toward the transformer tank and cooling surfaces.

Oil immersed transformer technology is widely used in electrical distribution systems because it is suitable for continuous medium-voltage power distribution when properly specified, installed and maintained.

100kVA 33kV Distribution Transformer

The 100kVA 33kV transformer provides a smaller capacity option within this product range.

It may be suitable for:

• Small commercial properties
• Workshops
• Offices
• Institutional facilities
• Small residential developments
• Agricultural facilities
• Light industrial applications

The 100kVA rating should only be selected after confirming that the calculated maximum demand is appropriate for the transformer’s capacity.

400kVA 33kV Distribution Transformer

The 400kVA 33kV oil immersed transformer provides substantially greater power distribution capacity.

It can be considered for:

• Factories
• Warehouses
• Hotels
• Shopping facilities
• Large offices
• Residential estates
• Industrial buildings
• Manufacturing facilities

A properly designed installation should include appropriate high-voltage and low-voltage protection.

500kVA 33kV Distribution Transformer

The 500kVA 33kV three-phase transformer is designed for higher electrical loads and can be specified for medium-to-large commercial and industrial installations.

Potential applications include:

• Manufacturing plants
• Industrial estates
• Large commercial buildings
• Hotels
• Shopping centres
• Large warehouses
• Residential developments
• Infrastructure projects

The transformer should be sized based on actual and anticipated electrical demand.

630kVA 33kV Distribution Transformer

The 630kVA 33kV oil immersed distribution transformer provides a high-capacity solution for appropriately engineered electrical distribution systems.

It can be used for:

• Large factories
• Industrial facilities
• Commercial complexes
• Industrial estates
• Large residential estates
• Infrastructure projects
• Private substations

The 630kVA transformer can supply substantial electrical loads when correctly integrated with the site’s protection, cabling and distribution infrastructure.

33kV Transformer High Voltage Bushings

The high-voltage side of a 33kV transformer requires appropriately rated HV transformer bushings.

A transformer bushing provides an insulated passage through the transformer tank for electrical conductors while maintaining electrical isolation between the energized conductor and grounded transformer enclosure.

Depending on the transformer design, the unit may include:

• 33kV HV bushings
• LV bushings
• Neutral bushing
• Phase terminals
• Cable connection points
• External conductor connections

The bushing voltage rating, current rating, insulation level, creepage distance and mechanical dimensions must match the transformer design.

Low Voltage Transformer Bushings

The low-voltage side of the transformer requires appropriately rated LV bushings and terminals for connection to the downstream distribution system.

These connections may interface with:

• LV cables
• Busbars
• Distribution boards
• Switchboards
• Industrial panels
• Building electrical systems

The exact low-voltage output should be confirmed when ordering.

Applications of 33kV Oil Immersed Transformers

Industrial Facilities

Factories and manufacturing plants can use 33kV transformers to supply production equipment, motors, pumps, lighting and other electrical systems.

Commercial Buildings

Large commercial properties can use dedicated transformers as part of their electrical distribution infrastructure.

Residential Estates

Large estates may require dedicated medium-voltage transformer installations to distribute electrical power to multiple buildings.

Private Substations

Industrial and commercial customers can incorporate a 33kV oil immersed transformer into a private electrical substation.

Infrastructure Projects

The transformers can also be specified for appropriately designed infrastructure and development projects.

How to Select the Correct 33kV Transformer

Selecting the right transformer requires more than choosing a kVA rating.

1. Confirm the Incoming Voltage

Verify that the electrical supply is compatible with the 33kV high-voltage winding.

2. Determine the Transformer Capacity

Calculate the site’s maximum demand and determine whether 100kVA, 400kVA, 500kVA or 630kVA is appropriate.

3. Confirm the Secondary Voltage

Specify the required low-voltage output according to the downstream electrical network.

4. Confirm Vector Group

The appropriate vector group should be determined from the electrical system design.

5. Confirm Impedance

Transformer impedance affects voltage regulation and fault-current levels and should be coordinated with the protection system.

6. Confirm Tap Arrangement

Where voltage adjustment is required, the appropriate tap arrangement should be specified.

7. Check HV and LV Bushings

The transformer bushings must match the electrical and mechanical requirements of the installation.

33kV Transformer Installation

Installation of a 33kV transformer should be performed by appropriately qualified electrical engineers and technicians.

Depending on the project, the installation may include:

• 33kV switchgear
• Circuit breakers
• Ring main units
• Lightning arresters
• HV cables
• Cable terminations
• Protection relays
• Current transformers
• Earthing system
• LV switchgear
• Distribution boards
• Metering equipment

The complete system should be inspected and tested before energization.

Transformer Maintenance

Proper maintenance helps support reliable transformer operation.

Regular inspection may include checking:

• Transformer oil
• Oil level
• Oil leakage
• HV bushings
• LV bushings
• Cable connections
• Transformer tank
• Earthing connections
• Terminals
• Protective devices
• Operating temperature
• Unusual vibration or noise

Any abnormal condition should be investigated by qualified transformer technicians before the equipment is returned to normal operation.
