RGSbtb

RGSbtb is a double transit which is packed from both sides, enabling on site pressure testing of the penetration. Installations with this transit can be pressure tested from the space between the pack block units. They also conform to jet-fire rating.

The system consists of a frame, rubber blocks and a compression unit.
The frame is welded to a marine structure and packed with rubber blocks suited for each cable and pipe dimension. The compression unit is inserted to compress the rubber blocks against cables and pipes to establish a tight seal.

Technical specifications 

An RGSbtb transit can be used to protect cables from water penetration, combined with EMC protection. One side of the packing takes care of water penetration and the other side gives EMC protection.

The frame is 10 mm (0.39”)thick on the ends and 12 mm (0.47”) thick on the sides. It is 200 mm (7.87”) deep. Other dimensions are the same as for the standard RGS.
RGSbtb is available in the four standard sizes: 2, 4, 6, and 8. They may be used in multiple frames.

Correct and safe installations

To achieve the highest standard of safety, a cable or pipe transit must be installed correctly. As there are many different types of frame – which may be either welded, bolted or glued into position – and insert block, it is essential that installers known when to use the most appropriate installation method.
