High reliability
The box shell of the pre-installed buried transformer can be selected with a fully sealed structure made of anticorrosive stainless steel plate and welded. The high and low voltage inlet and outlet lines are waterproof by the explosion-proof sealing system produced by Roxtetc company, so as to realize the waterproof connection mode with full seal, full insulation and full shield. It ensures the anti-corrosion and sealing ability of the buried transformer. The overall protection grade is IP68, which can be immersed in water for more than 90 days.
The high voltage is equipped with four-station load switch for the ring network to reduce the loss caused by transformer power failure. Meanwhile, it is also equipped with plug-in backup fuse, which can be quickly cut off in case of the night part or transformer failure without affecting the whole line.
In the design and manufacture of transformer pit foundation, waterproof and drainage are considered. The top ventilation hole has effective waterproof and waterproof function. The side and bottom are treated with special waterproof material, so that seepage water can enter.
The pre-installed buried box transformer can run submerged in water and resist flood and waterlogging disasters. All measures guarantee the 30-year service life of buried box transformer, which can avoid maintenance and inspection and repair, and effectively improve the reliability of power supply system.
Saving energy and reducing consumption
Energy saving and consumption reduction has become the consensus of the whole society. The buried transformer selected for the pre-installed buried box transformer is a low-loss product. The loss of the buried transformer with silicon steel sheet and iron core reaches more than S11 series. The loss of buried transformer with amorphous alloy core is greatly reduced, and its no-load loss is more than 90% lower.
Low noise
As is known to all, the most important factor affecting the surrounding residents of box-type substation can be said to be the noise of the transformer. The noise source of the transformer is mainly from the iron core. The transformer installed in the general transformer is generally about 1.2 meters from the ground. If the transformer is installed close to the residents' window, its noise will inevitably spread into the residents' room in the dead of night, which will affect people's sleep. However, once the transformer mask is placed underground, its noise can be significantly reduced, with little impact on residents.
Beautiful, in harmony with the environment
General box change occupies a large area, it is difficult to be well coordinated with the environment, especially in some high-end residential areas, Angle of view pollution sources are mainly in the distribution facilities or box type substation in the community can not be coordinated with the environment of the community, affect the overall beauty of the community, and even affect the selling price of nearby buildings.
As the transformer is installed underground, it does not affect the surrounding environment. The distribution box installed on the ground is small in volume and easy to coordinate with the surrounding environment. Be like in the life small area, the distribution box of the ground can form a complete set with green of small area, become a part of small area scene. Such as in the city main roads and highways, such as the ground distribution boxes can be designed as advertising light boxes.
Create value for customers
Change the area of small, in the living community, can replace the traditional power distribution room, reduce the construction of power distribution room, investment incubation is very obvious. The model is beautiful, coordinate with surroundings photograph, installation is in the life small area, not only do not affect surroundings aim to sell price, and can improve the grade of small area.
Socks in the city trunk road and highway instantaneous ton box change, on the ground advertising light box switch equipment, large advertising light box position will bring a long time for customers
