Cable Entry Frame

The SVLEC cable entry system contains KDL KEL KDP series.The traditionary method is to open holes in the cabinet body, and fix and lock the cables through the Cable Glands. According to the number of cables and the external Choose the number and size of the cabinet openings according to the diameter. Once the cabinet openings are opened, the number of openings should be increased in the future. It`s very difficult to measure, and at the same time, we found that for cabinets with a large number of openings, in order to meet the installation For space requirements, the cabinet needs to be made very Large.

By SVLEC cable entry system , can make it easier .Centralization and modularization can only cut out a small windows of block the cables , save a lot of time and have a very appearance.
