Overview of 30kVA Transformers
A 30kVA transformer is a medium-capacity transformer designed to step up or step down voltage in commercial, industrial, and utility environments. The “kVA” stands for kilovolt-ampere, which is a unit of apparent power. A 30kVA transformer is ideal for supplying power to small-to-medium scale electrical loads such as office buildings, equipment rooms, or industrial control panels.
Key Features of a 30kVA Transformer
- Power Capacity: 30 kilovolt-amperes
- Voltage Options: Common configurations include 11kV/400V, 33kV/400V, or 415V/230V
- Cooling Types: Oil-immersed or dry-type
- Mounting Options: Pole-mounted or pad-mounted
Standard Dimensions of 30kVA Transformers
The physical size of a 30kVA transformer depends on the design type—whether it’s a dry-type, oil-immersed, pole-mounted, or pad-mounted transformer. However, average dimensions can be estimated to help with installation planning.
Dry-Type 30kVA Transformer Dimensions
- Height: 600 mm – 1000 mm
- Width: 500 mm – 800 mm
- Depth: 400 mm – 700 mm
Oil-Immersed 30kVA Transformer Dimensions
- Height: 800 mm – 1200 mm
- Width: 600 mm – 900 mm
- Depth: 500 mm – 800 mm
Pad-Mounted 30kVA Transformer Dimensions
- Enclosure Height: 1000 mm – 1500 mm
- Width: 1000 mm – 1300 mm
- Depth: 800 mm – 1200 mm
Pole-Mounted 30kVA Transformer Dimensions
- Height: 700 mm – 1000 mm
- Diameter (Cylindrical Type): 500 mm – 800 mm
Note: Exact dimensions may vary slightly depending on the manufacturer, enclosure material, and design standards.
Typical Weight of 30kVA Transformers
Weight is a critical factor when planning for transportation, installation, and structural support. Here are the estimated weight ranges for different types of 30kVA transformers:
Dry-Type Transformer Weight
- Weight: 200 kg – 400 kg
Oil-Immersed Transformer Weight
- Weight: 300 kg – 500 kg
Pad-Mounted Transformer Weight
- Weight: 400 kg – 600 kg (including enclosure)
Pole-Mounted Transformer Weight
- Weight: 250 kg – 450 kg
Reminder: Always consult technical datasheets or the manufacturer for precise weights and installation requirements.
Factors Influencing Size and Weight
1. Type of Insulation
- Dry-type transformers use air as insulation, requiring larger windings and enclosures.
- Oil-immersed transformers use mineral oil or synthetic fluids, which also adds to the weight.
2. Cooling Method
- Natural air-cooled units (AN/AF) tend to be lighter.
- Forced air or oil-cooled types are heavier due to additional components like radiators and fans.
3. Core Material
- Silicon steel or amorphous cores differ in weight and efficiency.
4. Enclosure Type
- Pad-mounted transformers have weatherproof enclosures, increasing size and weight.
