MCT Ex - Round transit | RGP - SFR Ex
On land At sea Power Plant

The RGP Ex circular multi cable & pipe transits for assembly in sleeves, pipes, drilled or cast holes. It is available in eleven sizes and is packed with insert blocks. The compression bolts are tightened to compress the rubber blocks against cables and pipes to establish a tight seal. The metal parts are galvanized or stainless steel.

RGP - SFR Ex

For holes larger than the frame

The RGP Ex assembled in a sleeve with a flange that allows the frame to be welded into a hole which is slightly larger than the frame. It is supplied as a kit, complete with drilled holes, bolts, nuts, washers and a gasket or sealing compound.

For installations where cables are already in place, specify E-RGP - SFRBO which is an open version.

  • Ex system combined with EMC has yellow marking on the front face (see EMC instructions)
  • MCT Brattberg RGP Ex system must be installed with supplied sleeve.

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.

For more information, please view following instructions, videos or download manuals as PDFs.

 


PRESSURE-TIGHT INSTALLATION
All contact surfaces between the pipe and the RGP plug must be cleaned carefully prior to installation. Do not use any lubricant on these surfaces. All blocks must be lubricated carefully with MCT Brattberg lubricant. The penetration must not be subjected to pressure for at least 48 hours after installation. This is to allow the pressure to equalise throughout the penetration. It will take more time for the pressure to equalise at temperatures below 20°C.
Note: If the installation is subjected to pressure, all components must be replaced after removal and refitting.

General

The system consists of a round rubber frame (RGP Ex) and rubber blocks. The RGP Ex system must be installed with a MCT Brattberg sleeve as a kit, and packed with rubber blocks suited for each cable and pipe dimension. The compression bolts are tightened to compress the rubber blocks against cables and pipes to establish a tight seal.

The marking of the equipment and protective system:

Note: MCT Brattberg RGP Ex system must be installed with supplied sleeve.

Benefits of MCT Brattberg Ex systems

  • Ex rated transit for hazardous environments
  • Assists cable management
  • Seals the penetration against the passage of fire, water, gas, sound and environmental hazards
  • Can be combined with special EMC modules and for Grounding and Bounding
  • Unlike other brands our system can be dismantled and re-used
  • Cable dimension marked on block
  • No adaptation of standard blocks needed
