E-RGG

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

E-RGG 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.
E-RGG frame type is bolted onto a concrete wall or floor or a plaster board wall. It is manufactured from a 60x60x6 mm angle bar.

The E-RGG is also approved for grounding and bonding applications.

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-RGG sizes

The standard transit is made of an angle bar 60x60x6 mm, in mild steel, stainless steel or aluminium. The mild steel transits are supplied with two types of surface finish, primer or galvanized. The internal width is always 120.5 ± 0.5.

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

All the frames can be manufactured in combinations.

E-RGGO transit are of the same type as the E-RGG transits but with one of the ends removable which enables installation where cables already have been pulled.

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.
