As a prominent choice among suppliers and factories in China, the GCS drawer cabinet is extensively utilized in power, petrochemical, and telecommunications industries

Product Description

Environmental Conditions

  • Ambient air temperature: -15℃ to +40℃, with a daily average temperature not exceeding +35℃. Derating operation is required if conditions exceed this range.
  • Altitude: Installation height should not exceed 2500m.
  • Relative humidity: Not exceeding 50% at +40℃. Higher humidity is permissible at lower temperatures (e.g., 90% at +20℃). Consider potential condensation.
  • Installation tilt: Must not exceed 5 degrees, and the cabinet array should remain level.
  • Installation location: Free from severe vibration, impact, and corrosive elements that may affect electrical components.

Technical Characteristics

  • Flexible Structure: Built with 8MF type open steel profiles and a modular design (20mm module) allowing for interchangeable drawers.
  • Safety & Reliability: Functional units, busbars, and cables are independently isolated. Features clear indicators for positions (open/closed/test) and mechanical interlocking.
  • Short-Circuit Strength: Rear-mounted horizontal busbars provide enhanced resistance to electric shock and high currents.
  • Operational Efficiency: Push-pull drawer mechanisms and optimized cable compartments facilitate easy operation and maintenance.
  • Versatile Application: Ideal for systems with rated voltage up to 400V (690V) and current up to 4000A.
