The KYN28A-12 indoor metal-clad withdrawable switchgear, henceforth known as the switchgear, is a sophisticated and comprehensive power distribution apparatus meticulously engineered for 3.6 - 24 kV, three-phase AC 50Hz single-bus sectionalized systems. It plays a pivotal role in various power systems by offering multiple indispensable functions:
-Constructed with stainless - steel, which offers high durability, corrosion resistance, and protection for the internal components. This ensures a longer lifespan and reliable operation even in harsh environments.
-The SF6 ring main unit is designed to distribute medium - voltage electrical power in various applications. It can receive power from a source, such as a substation, and distribute it to multiple loads or feeders in industrial plants, commercial buildings, mining sites, and urban power grids. -It is equipped with switching devices that can isolate circuits for maintenance, control the flow of electricity, and protect the electrical system from faults.
-The VDE and CCC certifications ensure that the product meets strict safety standards. These certifications cover aspects such as electrical insulation, protection against electric shock, and protection against overheating, providing users with confidence in the product's safety performance.
-With its voltage range of 12kV - 40.5kV, it can be used in different types of electrical distribution systems, including those in factories, mining areas, city lighting networks, rural power grids, and schools. This wide applicability makes it a flexible solution for various power distribution needs. -Suitable for different occasions, such as industrial, commercial, and civil buildings.
