120-referenzen-power
The pressure balanced multi-ply axial expansion joints according to AD 2000 and CENELEC standards are used in a demanding environment. Tightness is important to ensure safe use in the gas-insulated switchgear. Thanks to kompaflex extensive equipment and test facilities, the Helium-Leakage test with overpressure could be carried out in house with our own experts.

Design pressure: +8 / -1 bar g
Test pressure: +16 bar g
Temperature: +70 °C
Movement: axial +/- 15 mm
Spring rate: axial Cx 2180 N/mm
Test: Helium leak test with 6 bar g overpressure
Leak rate: <1*10^-5mbar*l/sec (100% helium)
