Single Phase Overhead Type Pole Mounted Mild Steel Distribution Power Transformers is a single-phase pole-mounted transformer specifically designed for outdoor power distribution with a rated capacity of 50kVA. The main body is made of mild steel material, featuring anti-corrosion coating and earthquake-resistant design, suitable for harsh outdoor environments (-30°C to +40°C). The high and low voltage sides can be customized according to needs (e.g., 11kV/400V), supporting 50/60Hz frequency to meet different grid standards. This transformer uses natural air cooling, has high efficiency and low noise (<55dB), complies with IEC, IEEE, and national standard GB/T 6451, making it suitable for rural power grids, small industrial facilities, and overhead line distribution systems, offering both safety and reliability.

1.High-Voltage and Low-Voltage Sides Voltage

High-Voltage Side: Typically 10kV or 35kV, depending on the voltage level of the grid. The high-voltage side connects to the main grid, converting high voltage into low voltage suitable for end users.

Low-Voltage Side: Generally outputs 220V or 380V, used respectively for household electricity (such as lighting, appliances) and power supply for small industrial equipment (such as single-phase motors). This design ensures that the transformer can meet the power needs of different users.

2.Specific Application Scenarios

Rural Power Distribution System: In remote areas or villages, single-phase overhead transformers are often used to convert high voltage to low voltage, providing stable and reliable power supply to residents.

Urban Street Lighting: Widely used in street lamp power supply systems, providing lighting support for roads, squares, and public areas, ensuring nighttime safety.

Small Factories or Workshops: Suitable for single-phase machinery in small-scale factories, such as textile machines, cutting machines, etc., reducing operating costs.

Residential Area Power Supply: Provides power support for multi-story residential buildings or independent houses, ensuring daily life electricity needs.

Agricultural Irrigation Systems: Pole-mounted mild steel distribution power transformers provide power to agricultural equipment like water pumps, improving agricultural production efficiency.

Temporary Construction Sites: Used as a temporary power source in construction sites or temporary facilities, meeting the power needs of construction equipment.

3.Maintenance Notes for Single-Phase Overhead Transformers

Regular Insulation Testing:

Transformer insulation materials gradually degrade due to environmental factors (such as humidity, high temperatures), which may cause short circuits or leakage issues. It is recommended to perform an insulation test every six months to one year to ensure proper operation.

Cleaning Oil Stains and Dust:

Overhead transformers exposed to outdoor environments can easily accumulate oil stains, dust, or bird droppings. These contaminants can affect heat dissipation and even cause localized overheating. Regularly clean the exterior and heat sinks to maintain good cooling conditions.

Monitoring Temperature Changes:

During operation, if the transformer temperature abnormally rises, it may be due to excessive load or internal faults. Adjust the load promptly or shut down for inspection to avoid equipment damage.

Checking Connection Firmness:

High-voltage and low-voltage side terminals may loosen due to vibrations or thermal expansion and contraction, leading to poor contact or overheating. Regularly check and tighten the terminals to ensure reliable electrical connections.

Lightning Protection Measures:

Overhead transformers are prone to lightning strikes, so it is necessary to install surge arresters to protect the equipment from overvoltage damage.

Preventing Overloading Operation:

50kVA pole-mounted mild steel distribution power transformers have rated capacity limits. Long-term overloading can lead to overheating, shortened lifespan, or even damage. Plan loads reasonably to avoid exceeding the rated capacity.

Regular Lubrication of Moving Parts:

If the transformer is equipped with adjustable brackets or other moving parts, regular lubrication should be applied to reduce wear.
