General Product Overview ：
Our high-voltage switchgear is a comprehensive power control and protection solution designed for primary and secondary power distribution systems. These units (such as KYN28 series) are indoor, metal-clad, and withdrawable type, incorporating high-performance vacuum circuit breakers for safe and reliable electrical management. Engineered with the "Five-Prevention" interlocking system, they ensure the highest level of protection for both personnel and equipment. Their modular design allows for flexible installation, while the high short-circuit breaking capacity and superior insulation make them ideal for heavy-duty power grid and industrial applications.
