In 2019, two 2500 KVA transformers were exported to Cambodia with a rated capacity of 2500 KVA, a primary voltage of 22 KV, and a secondary voltage of 0.4 KV. These two transformers are used for local public utilities. The products have been specially customized, including enhanced insulation systems, additional cooling capacity, and seismic design to ensure long-term stable operation under the complex local climatic conditions and geological environment.
2500 kVA oil Filled Corrugated Transformer Product Description

Accessories for 2500 KVA Three Phase Oil Filled Distribution Transformer
- Conservator Tank:
- Function: Maintains the oil level in the transformer and allows for oil expansion and contraction due to temperature changes.
- Features: Fitted with a breather to filter out moisture and dust from the air entering the conservator.
- Breather:
- Function: Prevents moisture from entering the transformer oil by using silica gel.
- Features: Silica gel changes color as it absorbs moisture, indicating when it needs replacement.
- Buchholz Relay:
- Function: Detects gas accumulation and sudden oil flow in the transformer, indicating internal faults.
- Features: Provides an alarm and trips the transformer to prevent damage.
- Oil Temperature Indicator (OTI):
- Function: Monitors the temperature of the transformer oil.
- Features: Equipped with alarm and trip contacts to signal overheating.
- Winding Temperature Indicator (WTI):
- Function: Measures the temperature of the transformer windings.
- Features: Comes with alarm and trip contacts for over-temperature protection.
