Product category: product center box type substation Series Product Description: Schneider technology modular manufacturing humanized design safe and reliable perfect ventilation system American small size product details performance features: Schneider authorized Schneider authorized modular manufacturing. Humanized design, humanized design, convenient access to information. Safe and reliable, fully sealed, safe and reliable, reasonable structure, high reliability. Perfect ventilation system the box is equipped with perfect ventilation system, and the temperature control value can be set according to the needs. American style is small in size, compact in structure, only about 1 / 3 of the same capacity in Europe. Product introduction: humanized design, easy access to information. Taking the transformer as the main body, the high-voltage control and protection components such as high-voltage load switch and fuse are put into the transformer oil tank together with the transformer body, with compact structure; The volume of American type box transformer is smaller, which is similar to that of ordinary oil immersed transformer with the same capacity, only about 1 / 3 of that of European type box transformer with the same capacity; There is no difficulty in heat dissipation, so the overload operation ability of American box type transformer is relatively strong; The configuration of high and low voltage units is simplified, so the cost of American box type transformer is lower; If the American type box transformer adopts the high burning point transformer produced by our group company, the American type box transformer is more suitable for high temperature areas in summer; Using sealed oil tank, the transformer of American type box transformer does not need oil conservator, which reduces the regular maintenance workload of transformer. Use conditions: use place: outdoor and indoor altitude: ≤ 1000m, ambient temperature: - 30 ℃ ~ + 45 ℃, maximum daily average temperature + 30 ℃, minimum annual average temperature + 20 ℃, outdoor wind speed: ≤ 35m / s, relative humidity: daily average ≤ 95%     Monthly average seismic intensity ≤ 90%: Grade 8. If it exceeds the above requirements, please indicate it in the contract.
