Single-phase pad-mounted transformers are compact, self-contained electrical devices primarily used in residential and light commercial settings. Their primary application is to step down the high-voltage electricity supplied by the utility company to a lower voltage suitable for home or small business use.

Yawei's pad-mounted transformers are made in power ratings up to 167 KVA.High voltage up to 34.5 KV.

Yawei's pad mounted transformer is designed and tested in accordance with standards including IEC60076,ANSI,CSA, IEEE c.57, and DOE as applicable.

The pad mounted transformers are oil-filled and have a tamper-resistant design. Widely used in residential areas, commercial centers, stations and other places, suitable for outdoor installation without additional protective housing

Safety and Security: These transformers are typically enclosed in tamper-proof, lockable
metal cabinets. This design helps ensure safety, reducing the risk of accidental contact with live electrical parts.
Ease of Maintenance: Their design allows for easy access for maintenance and repair work. Utility workers can quickly open the cabinet to perform necessary tasks.
Voltage Regulation: They play a crucial role in voltage regulation, ensuring that the electricity supplied to homes and businesses is within the required voltage range.
Energy Distribution: These transformers are a critical part of the electrical distribution network, ensuring that electricity is
effectively and safely distributed from the power grid to the end-users.
Customization: They can be customized based on specific needs, such as varying power capacities, to cater to the requirements of different neighborhoods or facilities.
Reliability and Durability: They are built to be reliable and durable, often lasting many years with minimal maintenance, which is crucial for uninterrupted power supply. These transformers are essential components in the electrical distribution network, playing a key role in ensuring that electricity is safely and efficiently delivered to end-users.
