250kva Power Pole Transformer Oil Immersed 13200v To 120v Single Phase Pole Mounted Electrical Distribution Transformer

Winley Electric’s 250 KVA Single-Phase Pole Mounted Liquid-Filled Distribution Transformer serves as a critical end-of-line equipment in power distribution networks. Specifically engineered for urban and rural power distribution scenarios, it efficiently converts high-voltage electricity (13200GrdY/7620V) into low-voltage power (120/240V, L-N-L) required for residential, small commercial, and industrial applications. Compliant with ANSI/IEEE, CSA, and DOE 2016 energy efficiency standards, the product stands out for its exceptional stability, weather resistance, and easy installation, making it an ideal solution for residential communities, rural power grids, commercial parks, and agricultural power supply systems.​

Pole Mounted Transformer Parts

The following is the introduction of the main parts of the single-phase pole-mounted transformer. The main parts(accessories) on the single phase pole mounted transformer include high voltage bushing, low voltage bushing, oil fill valve, oil drain valve with the sampler, and pressure relief valve, Lighting arrester.

1. High voltage bushing
The main material of high voltage bushing is porcelain and its main role is to connect high voltage winding and external high voltage lines, insulation protection, protection against external intrusion, heat conduction and heat dissipation, etc., to ensure the normal operation and safety of the transformer.
2. Low voltage bushing
There are two types of low voltage bushing as spade type and clip type.
3. Oil fill valve
The role of the oil filling valve on the single phase pole mounted transformer is to fill the insulation oil into the tank.
4. Oil drain valve with sampler
The oil drain valve and sampler on the single phase pole mounted transformer are used to discharge air and moisture, remove sediment and impurities, ensure the quality and performance of the oil inside the transformer, and ensure the safe and stable operation of the transformer. Meanwhile, we can collect oil samples for analysis and testing.
5. Pressure relief valve
The pressure relief valve on the single phase pole mounted transformer is mainly used to protect the safe operation of the transformer, maintain normal working conditions, and adjust the gas pressure inside the transformer to ensure its stability and reliability.
6. Lighting arrester
The lighting arrester keeps the transformer safe from power surges caused by lightning, switching, and other HV sources. It shunts high voltage surges by grounding to avoid the direct impact of the transformer itself.
