⚙️ Product Description
Indoor Withdrawable Metal-Clad Switchgear Cabinet

This 12–35kV indoor metal-clad mid-mounted switchgear (KYN28A-12 / KYN61-40.5) is designed for industrial & commercial power distribution. It is widely applied in mining, industrial plants, new energy projects and municipal power grids, serving as an ideal matching device for transformers ranging from 100kVA to 2500kVA.

🛡️ Outstanding Safety & Multi-level Protection
  • Complete mechanical & electrical five-prevention interlock system, eliminating misoperation risks.
  • Enclosure protection degree up to IP4X, with independent compartment design to prevent fault spreading.
  • Standard arc flash protection, fast tripping within 10ms. Core components adopt epoxy solid insulation with Class 3 insulation level.
  • Partial discharge ≤ 5pC (35kV type); peak withstand current up to 130kA (12kV type).
📈 High Compatibility & Stable Operation
  • Rated current covers 630A – 3150A, customizable breaking capacity.
  • Wide temperature tolerance from -40°C to +55°C, anti-vibration and anti-corrosion.
  • Vacuum arc extinction without SF6 gas, eco-friendly and low loss. Distribution loss reduced by 8%.
📱 Intelligent Performance & Easy Maintenance
  • Mid-mounted truck structure, all operations completed from front side.
  • Maintenance time shortened to 1.5 hours with direct module replacement.
  • Equipped with intelligent temperature monitoring and partial discharge sensors; supports remote operation & maintenance (IEC 61850).
  • Cabinet service life exceeds 20 years.
