Air Load Break Switch

What makes Air Load Break Switch truly reliable? Is it because of its simple structure and stable arc extinguishing performance, or is it because of its safe operation that does not require gas or complex maintenance? At San Gao Electric, we believe the answer lies in all of these aspects. Our air load circuit breakers are designed specifically for medium voltage indoor and outdoor distribution networks (typically 12kV-24kV). It is used to connect and disconnect load currents and provide clear isolation during maintenance to ensure equipment and personnel safety. Air is used as an arc extinguishing and insulation medium, which makes the equipment more environmentally friendly and easier to maintain compared to SF - based on alternative solutions.
