11KV GIS electrical 3 Phase 4 Phase Dry Type Transformer Manufacturer for Dock
Product Description
- Preassembled substations are designed to be highly mobile and can be easily transported to different locations. This makes them a great option for temporary or emergency power needs, such as at construction sites or during natural disasters.
- These substations are typically designed for outdoor use and can be installed in a variety of locations, including on rooftops, on the ground, or even underground.
- Preassembled substations are often used in urban areas where space is limited, as they take up significantly less space than traditional substations. They are also popular in rural areas, where they can be used to provide power to remote locations.
- In addition to their compact size, preassembled substations are also designed to be easy to maintain. They often include features such as removable panels for easy access to the equipment inside.
- Preassembled substations are typically designed to handle a range of voltages and capacities, making them a versatile option for a variety of applications.
- These substations are often used in conjunction with other power distribution equipment, such as switchgear and distribution transformers, to create a complete power distribution system.

Material
1.The cabinet door adopts a double beveled edge process, which increases the structural strength of the same material by 50%.
2.The installation holes are all made using a multi-layer stamping and stretching process, which reduces the sliding wire situation by more than 80%.
3.The inlet and outlet holes adopt a composite structure of knockdown holes and square holes, which can be flexibly selected during on-site installation.
4.The box adopts a double folding process, which increases the structural strength of the same material by 50%.
5.The control circuit adopts a composite design of debugging mode and fire protection mode, greatly reducing the burning of fan and water pump equipment designed for fire protection during debugging.
