Pole Mounted Transformer 10Kva


Pole Mounted Transformer 12.47KV


ANSI Standard Single Phase Transformer

Product Description

ANSI IEEE Standard Single phase pole mounted transformer 10Kva 25kva 37.5kva 50kva 12.47KV



The transformer is cylinder sealing structure. Each one is fixed with grounding devices, hooks, sup porting lugs which conforms to ANSI standard, and one or two high voltage bushing on the cover, low voltage bushing on the wall of the tank and eyebolt,connecting terminals. The tap changer should be adjusted basing on the instruction after the power off.

Standard Feature


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.
7. Internal current limiting fusing
The fuse is used to limit the transformer winding from being damaged when there are overload currents.
8. Circuit breaker
One secondary circuit breaker is above the winding inside the tank and here are the operating handle, overload reset, and signal light. It has the function of thermal protection, low oil lever protection, and allowing a percentage of power to go through the breaker to restore service when it trips.
