KYN28-12 550mm narrow-width switchgear is a compact indoor medium voltage metal-clad withdrawable switchgear designed for 10kV power distribution systems. With an optimized cabinet width of only 550mm, this space-saving switchgear provides an ideal solution for substations, industrial facilities and containerized power distribution projects where installation space is limited.
Operating at 12kV / 50Hz or 60Hz, the KYN28-12 switchgear combines compact design with reliable electrical performance. The cabinet structure maintains sufficient insulation clearance, mechanical strength and operational safety while complying with international IEC standards.
Traditional medium voltage switchgear often requires large installation areas. The KYN28-12 550mm width switchgear adopts an optimized narrow cabinet structure, significantly reducing the footprint of the complete power distribution system.
This compact design makes it especially suitable for:
The KYN28-12 indoor switchgear adopts a fully metal-clad armored structure with independent functional compartments, including:
The compartmentalized design effectively separates different electrical sections, improving operation safety, maintenance convenience and fault isolation capability.
The KYN28-12 550mm switchgear supports installation of standard VS1 vacuum circuit breakers and various medium voltage components, including:
Its standardized configuration allows flexible integration into different medium voltage distribution systems and simplifies maintenance and component replacement.
The KYN28-12 metal clad switchgear is equipped with a mechanical and electrical interlocking system, including five-prevention safety interlocks, to prevent incorrect operation during equipment operation and maintenance.
The interlocking functions help prevent:
All electrical insulation distances, creepage distances and overall insulation performance of the KYN28-12 switchgear are designed according to international medium voltage switchgear requirements.
The product complies with:
This makes the KYN28-12 suitable for global medium voltage power distribution projects requiring reliable and standardized electrical equipment.
