American Type Combined Transformer Compact Substation
Lugao Power Co., Ltd. manufactures American Type Combined Transformer Compact Substation featuring a fully sealed design, integrating distribution equipment within the enclosure for easy installation and transportation. LUGAO's production technology is highly mature, enabling the company to export a significant volume of substations annually. The minimum order quantity is one unit, with professional export packaging and fast delivery times.
The high voltage side of the American Type High Voltage Substation connects 10kV or 35kV high-voltage cables to the interior of the box-type transformer via fully sealed bushings. The current passes through fuses before entering the transformer, where it is converted to low voltage, and then output to the low voltage unit. All distribution equipment is integrated within the box, featuring a compact design that saves space and facilitates installation and transportation. The fully sealed design prevents external moisture and air from entering the box, protecting internal components from oxidation. Suitable for densely populated areas such as commercial districts and residential areas.
The American Type Combined Transformer Compact Substation supports multiple wiring configurations and can be customized based on actual conditions. All components can be flexibly selected, and LUGAO's professional team can design cost-effective solutions for customers. The Outdoor Electrical Substation complies with multiple international standards, with a minimum order quantity of one unit and rapid delivery.

Operating Environment
1. Standard operating temperature range -25°C to 40°C
2. To prevent condensation, the standard operating humidity should be ≤95%
3. Installation is prohibited in areas prone to water accumulation to avoid prolonged exposure to water
4. Installation should be kept away from gas stations, fuel stations, and similar locations
5. Sufficient space for heat dissipation must be reserved, and the substation should not be installed at an angle.
Features
1 Compact structure, space saving, greatly reduced floor space
2 Fully sealed insulation, no exposed live parts, high protection level.
3 Integrated design, integrated design of various components, reducing external risks
4 Low loss, maintenance-free operation, long service life.
5 Strong overload capacity, adaptability to fluctuations in line with demand, and optimized heat dissipation structure.
6 Double fuse protection is used to reduce operating costs.
