Self - Cooled 25 KVA Pole Mount Transformer Product Features

Efficient Power Distribution：Adopts a high - efficiency energy - saving wound core structure. In decentralized power distribution networks, it reduces low - voltage distribution line length and line losses by over 60%, improving power supply quality.

Compact & Cost - Effective：Pole - type suspension installation results in a small volume, reducing infrastructure investment. It also shortens the low - voltage power supply radius.

Sturdy & Reliable：Fully sealed structure offers strong overload capacity and high reliability during continuous operation. It minimizes oil - air contact, delaying oil aging and lowering maintenance costs.

Versatile Application：Suitable for rural power grids, remote areas, scattered villages, agricultural production, and lighting. Can also be used in railway and urban power grid energy - saving renovations. Can operate as single - phase or be combined into three - phase for different load requirements.

Quality Materials & Standards - Compliant：Often uses high - quality materials like grain - oriented silicon steel sheet for the core and copper or aluminum for windings. Meets standards such as ANSI/IEEE, CSA, etc., and may have certifications like UL, CUL, SGS, CE.

The Function of Temperature Controller for Pole - Mounted Transformer

Temperature Monitoring

The temperature controller continuously measures the temperature of the self-cooled 25 kVA pole mount transformer. It uses sensors (such as platinum thermal resistors) to detect the temperature of key components like windings and oil (in oil - immersed transformers). This enables real - time monitoring of the pole - mounted transformer's operating temperature.

Over - temperature Alarm

When the measured temperature exceeds the preset alarm threshold, the controller triggers an alarm. This can be an audible and visual alarm, such as a buzzer sounding and an indicator light flashing. The alarm notifies operators that the pole transformer is approaching or has reached an unsafe temperature level, prompting them to take appropriate actions, like checking for overloading or cooling system issues.

Cooling System Control

For electric post transformers with cooling systems (such as fans or radiators), the temperature controller automatically controls their operation. When the temperature rises to a certain set value, it starts the cooling fans or activates other cooling mechanisms to reduce the temperature. Once the temperature drops below another set value, it stops the cooling system to save energy and prevent over - cooling.

Fault Detection and Protection

The controller can detect faults related to temperature sensors, such as sensor open - circuit or short - circuit. If a sensor fault occurs, it will usually trigger a fault alarm. Additionally, it helps protect the pmt transformer from damage caused by over - temperature, such as tripping the circuit breaker when the temperature exceeds a critical level to isolate the pole transformer from the power supply and prevent further damage.

Data Display and Recording

Some advanced temperature controllers have a display screen that shows the current temperature value of the pole mounted transformer with one winding. They may also be able to record temperature data over time. This historical data can be used for analyzing the pole transformer's operating conditions, predicting potential failures, and optimizing maintenance schedules.

How about the short - circuit withstand capability of your power transformers on pole?

Our oil type transformers are engineered with high - quality windings (such as copper or aluminum foil windings), which endow them with enhanced short - circuit withstand capability. This ensures the safety and reliability of the pole mounted transformers 3 phase during abnormal electrical conditions.
