Device for sealing a cable feedthrough

摘要

The cable gland sealing device has a frame (11) fitting around the cables (19) inserted through an opening in a partition wall at a given distance. It has filling and packing elements (23) inserted between the cables and between the cables and the frame. The frame is assembled from U-shaped frame elements (12) filled with fire-retardant pads (18). It incorporates a non-combustible layer (181) of mineral wool, or glass fibres and a fire retardant layer (182) which swells in response to heat.
