Cable strut helium mass spectrometry leak test helium test by negative pressure method

202 cable pillar (inflatable cabinet) provides the interface for the cable connector, the product is mainly used in the American box, outdoor ring switch cabinet and other equipment. It is installed on the box transformer and connected with the high voltage winding, and installed on the outdoor ring network switch cabinet to make a wire line. Its body is formed by epoxy resin material, and has good mechanical and electrical properties.

The leak detection of the cable pillar is also suitable for the leak detection of the fuse tube, and the leak detection is carried out by the helium mass spectrometry leak detector [negative pressure method].

Specific method: Put the product on the tooling of the equipment, click the start button, and then the equipment vacuums the lower end of the product. When the preset vacuum degree is reached, the airbrush connected with helium gas is used to spray helium gas to the other end of the product, and the equipment automatically detects. If the product leaks, helium will enter the device through the channel leak hole inside the product, and the device will alarm if it exceeds the preset alarm value. After the leak detection is over, press the Start button again to stop the leak detection, remove the product, and perform the next leak detection operation.
