Overview of 500 KVA Transformers
The 500 kVA transformer is a medium-sized power distribution unit widely used across industrial, commercial, and renewable sectors. It serves as a critical element in transferring electrical energy from the distribution grid to internal building systems or machinery with stable voltage and high efficiency.
Technical Specifications of 500 KVA Transformers
500 kVA transformers can vary by manufacturer and application. Below are the common technical specifications:
- Rated Capacity: 500 kVA
- Frequency: 50 Hz / 60 Hz
- Primary Voltage: Up to 38.5 kV
- Secondary Voltage: Common options include 400V, 415V, or customized based on demand
- Cooling Method: ONAN (Oil Natural Air Natural) or ONAF (Oil Natural Air Forced)
- Insulation Class: Class A or F
- Winding Material: Copper or Aluminum
- Protection Rating: Typically IP44 to IP54 for outdoor use
Typical Dimensions of 500 KVA Transformers
Although the dimensions can vary depending on design (dry-type, oil-immersed, pad-mounted), here are common dimension ranges:
- Height: 1400mm – 1700mm
- Width: 1000mm – 1300mm
- Depth: 800mm – 1200mm
- Weight: 1000kg – 1500kg
Note: Pad-mounted transformers generally come in fully enclosed cabinets that may have slightly larger footprints for cooling systems and protective housing.
