Vacuum Chamber Helium Leak Detection System for Power Insulators & GIS Components

2026-08-05

 

Safeguard high-voltage electrical infrastructure against dielectric breakdown with our advanced vacuum chamber helium leak detector. Custom-built for power transmission and distribution OEMs, this automated system delivers fast, reliable SF6 and gas-tightness testing for heavy-duty electrical insulators, switchgear housings, and transformer bushings.

Target Applications in Power Equipment:

  • Electrical Insulators: Porcelain, composite, and epoxy resin insulators for high-voltage switchgear.

  • GIS & Switchgear Housings: SF6 and eco-gas filled enclosures, bus ducts, and sealing flanges.

  • Transformer Bushings: Ensuring long-term dielectric performance and environmental safety.

Key Technical Features:

  • Heavy-Duty Roller Conveyor: Integrated track and roller loading system allows effortless handling of bulky, heavy power components.

  • High-Precision Mass Spectrometry: Pinpoints ultra-fine micro-leaks down to 10-7 mbar.L/s — 10-9 mbar.L/s

  • Cost-Saving Helium Recovery: Built-in automated helium recovery system reclaims up to 98% of test gas, significantly lowering daily operating expenses.
