E-RGP System At Sea On land EMC G&B

These EMC cable and pipe transits are used in high-risk maritime, offshore and land-based environments to minimize danger by preventing the spread of fire, water, gas, chemicals and other hazards substances.

The system consists of a round rubber frame (E-RGP or E-RGPO) and rubber blocks. The E-RGP or E-RGPO is assembled in sleeves, pipes, drilled or cast holes 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.

Benefits of MCT Brattberg E-systems

  • Protects against electrical and magnetic interference (EMI), “bugging”, electronic sabotage (SEMP) and static electricity (ESD).
  • Assists cable management.
  • Integral earthing between cables and wall screen.
  • Also seals the penetration against the passage of fire, water, gas, sound and environmental hazards.
  • Special E-Series for Grounding and Bounding
  • System can be dismantled and re-used.

Overview

E-RGPO is a RGP with an open side intended for installation in holes where cables have already been pulled.


Sleeves are available in several diameters to suit each RGP/RGPO size. They can be welded, casted or bolted to a structure. The standard materials are mild steel, stainless steel or aluminum.
Sleeves for EMC is not painted.

SFR/SRFB are supplied as kits, complete with drilled holes, bolts, nuts, washers and a gasket or sealing compound.

In the RGP frames no compression system or stayplates are necessary. Therefore the packing space consists of the entire interior area of the frame.

Instructions

EMC

  • All dimensions are exactly the same for the standard MCT Brattberg components.
  • All Insert Blocks are marked with yellow marking (see instructions).

Grounding and Bonding

  • For grounding & bonding applications standard presswedge or endpacking is sufficient. 
  • Series E-RGS, E-RGB, E-RGG, and E-RGP These products are primarily intended for grounding and bonding of communication, instrument, power, braid or wire armored cables and copper pipes.
  • Plugs and Wraps are only for use in Grounding and Bonding applications, not EMC

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
E-RGP 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.
