Product Description

The KYN28 central cabinet is a metal-clad, withdrawable AC metal-enclosed switchgear that is widely used in 3.6kV to 24kV three-phase AC 50Hz single busbar systems to receive and distribute electrical energy. The following is a product introduction to the KYN28 central cabinet:
1. Main features:
Compact structure: It is designed with a metal armor, which takes up little space and has a reasonable layout of internal components.
Safe and reliable: The interior of the cabinet is separated by metal partitions, which can effectively prevent phase-to-phase or phase-to-ground short circuits, enhancing the safety of the equipment.
Modular design: Easy to maintain and expand, with individual components that can be removed and replaced independently.
High-performance vacuum circuit breakers: Equipped with advanced vacuum circuit breakers, which have good arc extinguishing performance and long life.
Intelligent monitoring: Optional intelligent control and protection units can be used for remote monitoring and management.
2. Scope of application:
It is widely used in power plants, substations, industrial enterprises and other places that require highly reliable power distribution.
It is suitable for indoor installation, has a high degree of protection and can operate stably in harsh environments.
