7.2KV 13.8KV 34.5 KV Pole Mounted Transformer

This is a standard single-phase pole-mounted transformer, also known as a pole transformer or a single-phase oil-immersed distribution transformer. These transformers are commonly used for distributing electrical power in overhead power lines, typically mounted on utility poles for efficient distribution in rural or suburban areas.
This product is designed for efficient power distribution in smaller-scale, single-phase applications and is ideal for areas where compact and lighter equipment is needed, such as rural or suburban power grids.

1. Structure and Installation Features

• Cylindrical Fully Sealed Oil-Immersed Structure: The transformer adopts a classic cylindrical, fully sealed oil-immersed design with a high-voltage insulator on the top and low-voltage connection terminals on the sides. This design is specifically suited for mounting on utility poles, making it a typical pole-mounted transformer.
• Mounting Brackets: The sides of the transformer are equipped with mounting ears for direct attachment to utility poles, meeting the installation requirements for "pole-mounted" transformers.

2. Capacity and Application

• Rated Capacity of 50kVA: This is one of the most commonly used small capacities for pole-mounted transformers. It is used at the ends of urban and suburban distribution networks, stepping down medium voltage (10kV/12kV, etc.) to 220V/240V for residential and small commercial use.

3. Terminal Markings Meet Industry Standards

• Terminal Identification: The X₁, X₂, and X₃ labels on the side of the transformer are for low-voltage side connection terminals, and the ± symbol indicates the ground terminal. This is a universal marking standard for single-phase pole-mounted transformers.

4. Clear Application Scenarios

• Application Areas: This type of transformer is a mainstream pole-mounted device in the distribution systems of North America, Southeast Asia, and other regions. It is also widely used in rural and suburban single-phase power supply scenarios in China, fully meeting the definition of a pole-mounted transformer.

5. Additional Information:

• Single-phase vs. Three-phase Pole-Mounted Transformers: This is a single-phase pole-mounted transformer, distinct from the three-phase version, primarily used in single-phase power supply scenarios. Its design is more compact and lighter, making it more suitable for single-pole mounting.
