General Description:
The skid-mounted substation by Ningbo Dowei Electric Co., Ltd. adheres to international standards such as IEC 62271, ANSI/IEEE Std C37, and NEMA. It is certified by ISO 9001, KEMA, CESI, CE, TUV, UL, and ASTA. The design incorporates seismic considerations per ETGI-1.020, IEEE Std 693, and NCh2369, and follows structural standards like ASTM A325, ANSI/AISC 360, and AWS D1.1. It is suitable for high altitudes up to 5000 meters, offering high reliability, smart, modular, and economic solutions. The substation is designed for flexibility, allowing for fast, modular, and optimized layouts with plug-and-play power supply capabilities. It is ideal for both temporary and permanent applications in industries such as Mining & Minerals and Oil & Gas, featuring a skid-based frame for mobility and standalone mechanical and electrical design.
