Product Description
Medium Voltage Low Voltage 480V Outdoor Type Power Distribution Substation
Product Description
- Box-type substation is a fully enclosed and movable steel structure box that combines multiple high-voltage switchgear systems, armored busbars, substation integrated automation system, communication, remote control, measuring, capacitor compensation, and DC power supply electrical units.
- It is characterized by electromechanical integration, fully enclosed operation, and advanced safety features such as no exposed live parts, corrosion resistance, and fireproof insulation.
- The substation has a high degree of automation and can achieve unmanned operation through a comprehensive microcomputer automation system.
- It is prefabricated in the factory, shortening the design and manufacturing cycle, and on-site installation only requires a few days.
- The combination method is flexible and can be customized according to actual needs, and it is cost-effective, reducing investment by 40% to 50% compared to conventional substations.
- The substation has a small footprint, occupying minimal land, making it suitable for use in densely populated areas.
- The box-type substation is widely applicable in urban and rural power grids, industrial and mining enterprises, and other power users, and it will play an increasingly important role in the construction of power grids and the improvement of power supply reliability.
