KYN28A-12 Indoor Metal-Clad Withdrawable Switchgear: Experience the pinnacle of electrical distribution with our high-tech, state-of-the-art KYN28A-12 switchgear. Designed for optimal performance, reliability, and ease of use in various environments.
The KYN28A-12 This indoor metal-clad withdrawable switchgear (referred to as the switchgear) is an all-in-one power distribution marvel, meticulously engineered for 3.6 - 24 kV, three-phase AC 50Hz single-bus sectionalized systems. It performs an array of crucial functions across diverse power systems:
- Power Plant Applications:Primarily harnessed for power transmission of medium-to-small generators in power plants, this switchgear ensures seamless and efficient transfer of generated electrical energy to the power grid or other connected infrastructures.
- Substation and Distribution Applications:Within substations of power distribution networks and in factory, mine, and enterprise power systems, our switchgear plays an indispensable role in power reception and transmission, enabling smooth and efficient distribution of power to various end-users and facilities.
- Motor Starting:Employed for initiating large high-voltage motors, it expertly manages electrical currents during motor start-up, effectively protecting the motor from potential over-current or voltage surge damages.
Functionally advanced, the switchgear is engineered to precisely control, protect, and monitor the electrical systems. It aligns with international and national standards, especially adhering to IEC298 and GB3906-91, ensuring reliability, safety, and unrivaled compatibility across a broad spectrum of applications.
Regarding component compatibility, this switchgear is not only compatible with domestic VS1 vacuum circuit breakers but can also be deftly integrated with renowned international and domestic components such as VD4, Siemens' 3AH5, domestic ZN65A, and GE's VB2. This diverse compatibility enhances flexibility in system design and customization.
To cater to the specific needs of wall-mounting installation and front-end maintenance, the switchgear features a specialized current transformer. This innovation allows for convenient maintenance and inspections directly from the cubicle's front, significantly enhancing the equipment's overall maintainability and accessibility. The KYN28 indoor metal-clad withdrawable switchgear stands as a high-performance power distribution device that perfectly marries reliability, compatibility, and user-friendly features.
