Product Introduction：
The new energy prefabricated substation is a modular, prefabricated power distribution equipment specially designed for new energy projects such as photovoltaic and wind power connected to the grid. It integrates a step-up transformer, high-voltage switch, low-voltage distribution and intelligent monitoring system in a fully sealed enclosure, which is suitable for the voltage boosting and grid connection requirements of new energy projects. It is also versatile for different tough outdoor conditions such as deserts, Gobi and coastlines. It is IEC standard compliant, has high weather resistance, low loss and intelligent monitoring, the first choice for new energy projects around the world.
Application scenarios:
This type of transformer is widely used in new energy grid-connected systems with the frequency of 50Hz/60Hz and the rated voltage of 35kV and below. It is especially suitable for:
1. Large-scale PV power plants: Large solar farms boost voltage up to grid level, reliably and efficiently.
2. Onshore wind farms: capable of wind power project, impact load resistance, stable operation.
3. Middle East desert projects: high temperature of 55℃, dust-proof, reliable in harsh environment.
4. Projects in coastal areas of Southeast Asia: Anti salt fog, anti humidity, applicable to coastal renewable projects.
Product Feature：
1. Integrated design, factory pre-assembly, quick installation, save project time.
2.High weather resistance, can resist -40℃~+60℃, anti-salt fog, anti-dust, suitable for harsh environment.
3. Low loss design, with optional amorphous alloy core, reduces no-load loss by 70%, ideal for light load at night.

New Energy Prefabricated Substations Structure and Working Principle:
New energy prefabricated substation is a new type of prefabricated modular power distribution equipment developed for new energy projects. They integrate a step up transformer, high voltage switch, low voltage distribution and an intelligent monitoring system into a single fully sealed enclosure. The unit converts the low voltage output of the new energy inverter to the medium voltage required by the power grid to achieve grid connection. Therefore it has compact structure, easy installation, good weather resistance, and can be safely used in various harsh outdoor environment such as desert, Gobi, coastal areas.
The main components of a new energy prefabricated substation are: step-up transformer, high voltage switch unit, low voltage distribution unit, intelligent monitoring unit and fully sealed enclosure. The transformer - for increasing the voltage. The switch unit - for protection. The low-voltage unit - for connecting the inverter. The monitoring unit - for remote monitoring. The enclosure - for protection. Putting it all together you have one new energy grid connection solution.
New energy prefabricated substation is used for new energy grid connection. All parts are pre-assembled in the factory. Installation is as simple as putting the enclosure on the ground and connecting the inverter and grid cables. This very convenient installation greatly reduces the construction cost and time for new energy projects and there is no need to build an additional substation
Why we use new energy prefabricated substations?
1. New energy prefabricated substations can be directly installed at the site of new energy projects, without the need for additional substation construction, greatly reducing construction costs and time, and is especially suitable for rapidly deployable new energy projects. They can work well in a range of severe environments, such as deserts, the Gobi, and coastal areas.
2. New energy prefabricated substations have very high energy efficiency, and the power loss is very small, especially when the load is light at night, which saves energy and reduces the long-term operating costs of users. In addition, the monitoring design is intelligent, which is maintenance-free, truly achieving maintenance-free, greatly reducing the maintenance cost.
