High-Performance Power Transfer with Gas-Insulated Systems

In modern power systems, especially where space, reliability, and safety are critical, gas-insulated busducts (Gasducts) offer a superior solution for transmitting large currents in LT (Low Tension) and HT (High Tension) systems. At 3 Phase Power Solution, we provide specialized Gasduct Services—from installation and testing to inspection and maintenance—for a range of industrial and utility applications.

What Are Gasducts?

Gasducts are gas-insulated busduct systems (typically using SF₆ or other insulating gases), enclosed in a metal casing, used for transmitting high current at high or medium voltage with minimal phase clearance and maximum insulation reliability.

They are ideal for:

  • Power plants and substations
  • Compact indoor switchgear connections
  • Generator-to-transformer interconnections
  • High-current industrial applications

Our Gasduct Services Include

🔧 Installation

  • Layout planning based on load, voltage level, and space constraints
  • On-site assembly, jointing, and pressurization
  • Interface connections to generators, transformers, and panels

🧪 Testing & Commissioning

  • Leak testing of gas compartments
  • High-voltage dielectric strength testing
  • IR testing and contact resistance measurement
  • Functional testing of joints, seals, and expansion units

♻️ Servicing & Preventive Maintenance

  • Gas pressure monitoring and top-ups
  • Inspection of sealing rings, insulators, and joints
  • Thermal scanning and corrosion checks
  • SF₆ gas handling and safe disposal (if required)

🔄 Retrofitting & Upgrades

  • Conversion of air-insulated to gas-insulated systems
  • Upgrading old joints or seals for extended life
  • Integration with new panels or switchgear layouts

Benefits of Gasduct Systems

✅ High Safety: Superior arc containment and insulation
✅ Reliable Operation: Resistant to environmental conditions like dust and moisture
✅ Low Maintenance: Sealed system reduces routine servicing needs
✅ Ideal for Harsh Environments and high-capacity installations
