KYN28-12 AC metal armored switchgear is suitable for three-phase AC power system with rated voltage 12kv, rated frequency 50Hz, used to receive and distribute electric energy and control, protect and monitor circuits
The KYN28 series AC metal armored switchgear, also professionally referred to as metal clad switchgear (or switchgear metal clad), is a high-performance air insulated switchgear (AIS) and mainstream medium voltage switchgear tailored for three-phase AC power systems with a rated voltage of 12kV and a rated frequency of 50Hz. As a professional kyn28 switchgear supplier, we offer this core distribution switchgear purpose-built to receive and distribute electric energy, as well as execute control, protection, and circuit monitoring functions across diverse power distribution networks. For systems demanding higher voltage levels, the 34.5 kV switchgear variant is also offered, delivering an efficient and robust solution for more challenging power applications.
The KYN28 12 model complies with stringent international and national standards, including GB3906-2006 for 3.6~40.5kV AC Metal-enclosed Switchgear, GB11022-89 for General Technical Conditions for High Voltage Switchgear, IEC298(1990) for rated voltage 1~50kV AC Metal-enclosed Switchgear, and DL404-97 for Technical Conditions for Ordering Indoor AC High Voltage Switchgear. This strict standard adherence guarantees that the KYN28 series metal clad switchgear provides dependable and regulation-compliant performance as a reliable air insulated switchgear (AIS) and versatile medium voltage switchgear in a full range of industrial and utility power distribution environments.
