DESCRIPTION
Single-phase pole mounted transformers find wide applications in industrial, commercial, and residential sectors. In industrial settings, they are often used in power distribution, substations, and control systems. In the commercial sector, they can be employed for power supply in buildings, shopping malls, and office complexes. In homes, they can be used for powering electronic devices, lighting, and other electrical appliances.

Features Of Pole-Mounted Distribution Transformers
Voltage Transformation:
The primary function is to transform higher voltage electricity from the distribution lines to lower voltage levels suitable for local consumption. Typically, these transformers step down voltage from medium voltage to low voltage (e.g., from 7.2 kV or 12.47 kV to 120/240 volts).
Phases:
Pole-mounted distribution transformers can be designed for single-phase or three-phase power distribution. Single-phase transformers are commonly used for residential areas, while three-phase transformers are more common in commercial and industrial settings.
Enclosure and Weatherproofing:
The transformers are housed in weather-resistant enclosures to protect them from environmental elements such as rain, snow, and sunlight. This enclosure is designed to withstand outdoor conditions and ensure the transformer’s longevity.
Cooling:
Cooling methods may include natural convection or forced air cooling. Some transformers have cooling fins or other features to dissipate heat efficiently.
Capacity:
Pole-mounted distribution transformers come in various capacities, ranging from a few kVA to several tens of kVA, depending on the specific requirements of the distribution area.
Connections:
These transformers have primary and secondary windings, and the connection configuration is determined by the specific distribution requirements. The primary winding is connected to the distribution line, and the secondary winding supplies power to the end-users.
