What exactly is this cascading sealing principle? The term “cascade” is encountered, for instance, in the natural world. In this context a “cascade” (from the Italian cascare “falling”) means a multilevel waterfall. This effect was artificially replicated by people in ancient times and can now be found in our modern gardens and parks. Natural waterfalls may also have taken on this cascading form. The most famous example of a cascading waterfall in Germany is the Kuhschlucht (“cow gorge”) in Garmisch-Patenkirchen.
The world of science and technology has also discovered this term for its own uses. Here, the cascade effect is a metaphor for the most diverse processes that run on different levels, following the principle of the cascade. So-called energy cascades arise during metabolic processes in biological cells or in ecological systems. In control systems and electrical engineering applications, the arrangement of modules and/or processes is termed a cascade or serial connection (cascading).
At PFLITSCH the cascading sealing principle refers to a significant product characteristic of the LevelEx cable gland. The sealing elements comprise a high-grade silicone seal and a transparent pressure sleeve. The seal attached to the cable (level 1) is deformed over a large-area as the pressure screw is tightened (level 2) and therefore has the effect of achieving highly effective sealing and strain relief on the cable. This two-level sealing principle also prevents the cable from twisting during assembly. This is the cascading sealing principle according to PFLITSCH.
