Reservation of cable entry points into the distribution box

Cable entry systems are used for routing electrical cables, corrugated conduits or pneumatic and hydraulic hoses into switch cabinets, electrical enclosures, control panels and machines or in large heavy-duty vehicles, rolling stock and ships. Possible requirements can be high ingress protection rates or integrated strain relief. It is being differentiated between entry systems for routeing standard cab. HistoryFrom the 50s on, machines and switch cabinets were more and more wired by using heavy-duty industrial. For routing of standard cables and other electrical, pneumatic or hydraulic lines through machine, panel or enclosure walls, cable glands, or gland plates can be used to seal the cut-outs required fo. For routing cables which are already assembled with, split cable entry systems have been developed. The divisibility of these systems provides two advantages. The warranty on pre-terminated. [PDF]
