E-MCT - Marine & Offshore
At sea Submarines Ships and vessels

EMC and G&B multi cable & pipe transits for maritime and offshore applications. The EMC transits & components provide the same sealing as the standard MCT Brattberg system but with added, built-in protection against electromagnetic pulse (due to lightning or nuclear blast) and interference (EMI), electronic sabotage (synthetic EMP) and static electricity.

RGS EMC multi cable transit

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 RGS, RGB, 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, up to max. 1 AWG.
  • Plugs and Wraps are only for use in Grounding and Bonding applications, not EMC.
  • G&B Datasheet

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.

MCT Brattberg E-series Installation

For more information visit Instructions and manuals

Standard frames come in eight sizes: 1, 2, 3, 4, 5, 6, 7, and 8. 
The internal width can be 60.5 ± 1 (Size 1,3,5,7) or 120.5 ± 1 (2,4,6,8).

Note that there can be limitations in type-approvals & certificates, making certain sizes inapplicable.

The EMC secret is a tempered metal sheet which systematically stops electrical current from passing along the cable screening through the seal and successfully function as an extended wall screen. 

For size and weight please see tables in the MCT Online Catalogue:

General

The system consists of a frame, rubber blocks and a compression unit. The frame is casted or bolted to a 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.

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.
