The 13.8kV metal clad air insulated switchgear is a critical medium-voltage power distribution solution designed for substations, industrial facilities, and utility networks where safety, reliability, and operational continuity are non-negotiable. Engineered with fully metal-clad compartments and air insulation technology, this switchgear provides dependable protection, precise control, and long-term operational stability for modern power systems.
As a professional manufacturer, Lugao Power delivers 13.8kV metal clad AIS solutions that meet international standards, ensuring stable performance under demanding electrical and environmental conditions.
The 13.8kV metal clad air insulated switchgear features a compartmentalized structure that separates busbar, circuit breaker, cable, and control sections. This design effectively minimizes fault propagation and enhances operator safety. Compared with conventional open-panel systems, metal clad AIS offers higher protection levels, easier maintenance, and improved system reliability, making it a preferred choice for medium-voltage substations worldwide.
Each functional unit is enclosed in grounded metal compartments, providing superior protection against internal arc faults and external interference. This structure significantly improves personnel safety and system stability.
Using air as the primary insulation medium eliminates the risks associated with SF₆ gas or oil insulation, offering an environmentally friendly, cost-effective, and easy-to-maintain solution.
The draw-out vacuum circuit breaker allows for safe inspection, replacement, and maintenance without shutting down the entire system, reducing downtime and improving operational efficiency.
Designed to handle rated voltages up to 13.8kV with excellent short-circuit withstand capability, the switchgear ensures reliable operation even under high-load or fault conditions.
