The standard says that an insulator tested at 10-1 mbar*l/sec is considered to be tight. But Reinhausen says that tighter is always better.
Here, a ReCoTec® composite hollow insulator, built by Reinhausen Power Composites and measuring five meters in length, is being held in place by the Pegasus 5000 test system. No two jobs that the system handles are ever the same, but it always knows exactly which parameters the customer’s equipment needs to abide by. When the rolling shutter closes, the system is ready is to start testing the insulator, which will be required to withstand exceptionally high levels of bending and compressive force while remaining totally leak-tight. During the Helium chamber test, the Pegasus 5000 is able to sniff out even a single molecule of escaping gas — so not even the tiniest leak will get past it. Not only that, but it is hundreds of times more accurate than the standard requires it to be.
