Zero-Leak Assurance for High-Voltage GIS Basin Insulators

2026-08-07

 

In high-voltage GIS switchgear, even a microscopic casting void or boundary flaw in an epoxy resin insulator can lead to SF6 gas leakage and catastrophic grid failure. However, for shop-floor operators, repeatedly lifting heavy, brittle insulator discs into traditional deep vacuum chambers is exhausting and risks product damage.

Our DXF-620 Vacuum Chamber Helium Leak Detection System is purpose-built to solve both testing precision and operator ergonomics.

Featuring low-height multi-station chambers paired with motorized shuttle loading platforms, your team can load basin insulators at a comfortable working height. Once loaded, the automated system seals, evacuates, and runs ultra-sensitive mass spectrometry—identifying micro-leaks down to 10-7 mbar.l/s~10-9 mbar.l/s.

Why Power Equipment Manufacturers Choose This Line:

  • Operator-Friendly Design: Ergonomic low loading height, safety light curtains, and clear visual alarm beacons keep workflow smooth and safe.

  • Massive Helium Savings: An integrated closed-loop helium recovery system (shown with our large gas buffer tank) reclaims up to 98% of test gas, dramatically lowering operating costs.

  • Continuous Throughput: Multi-chamber parallel operation ensures zero operator waiting time during evacuation cycles.
