Product features

• Structural safety and reliability: Adopting an armored metal enclosed structure, each functional unit is strictly separated by metal partitions, effectively preventing the spread of faults and achieving a high level of protection.
• Easy operation and maintenance: The core components adopt a detachable handcart structure, which can be easily pushed in or pulled out for quick maintenance.
• Excellent electrical performance: Strong insulation performance, excellent short-circuit resistance and dynamic thermal stability, capable of stable operation in complex power grid environments.
• Comprehensive functionality: It integrates functions such as power reception, distribution, control, and protection, and can be remotely monitored in conjunction with intelligent control systems to meet modern power distribution needs.
• Good environmental adaptability: The cabinet is made of high-quality steel and has undergone anti-corrosion treatment on the surface, making it suitable for indoor dry or dusty industrial and commercial places.
