Dead front pad mounted transformer with its moderate capacity, high adaptability and low cost, offers an extremely high cost-performance ratio in small and medium-sized power distribution scenarios, making it an ideal choice for balancing electricity demand and investment costs.
Introduction:
Dead front pad mounted transformer is a three-phase enclosed distribution transformer. It is specially designed for outdoor installation and is widely used in scenarios of energy conversion from medium and high voltage to low voltage. Its capacity is moderate, which can not only meet the electricity demands of small and medium-sized users, but also possess the unique compactness and outdoor adaptability of box-type transformers. It is a key device in the distribution network that connects medium and high voltage power grids with end users.
Parameters and basic specifications:
High voltage: 10/20/35kv.
Low voltage: 400/230v, usually depending on the customer’s requirements.
Phase number: 3 phases
Frequency: 50/60Hz
Insulation type: The mainstream is oil-immersed type.
Cooling method: Oil-immersed type is mostly natural cooling, with heat dissipation through the heat sink of the box body. If the ambient temperature is high or the load is heavy, fans can be installed for forced cooling.
Performance features and advantages:
Suitable for small and medium-sized power consumption scenarios:
Daily electricity consumption in small residential communities;
Three-phase power and lighting electricity for medium-sized commercial premises;
Power supply for production equipment in small factories.
Convenient for outdoor installation
No dedicated machine room is required. It can be directly placed on a concrete base, with low installation costs. The box design is compact and occupies a small area, making it suitable for places with limited space such as green belts and roadsides.
High safety and reliability
The high-voltage part is fully enclosed, with only the low-voltage side reserved for operation interfaces, reducing the risk of electric shock to personnel.
Oil-immersed type has good insulation and heat dissipation stability, and its service life can reach 20 to 30 years.
The box has strong protective ability and can adapt to an ambient temperature ranging from -25 ℃ to + 40℃.
Low loss and energy saving
It meets modern energy efficiency standards, with low no-load and load losses. Long-term operation can reduce power waste and lower users’ electricity costs.
Easy to maintain
Daily maintenance only requires regular checks of oil level, temperature and whether the cable connection is loose, without the need for complex operations. When a fault occurs, components can be quickly replaced through the inspection door.
