EMC transits

In addition to its trusted program of transit systems, MCT Brattberg also has an EMC variant in its range. The basis is formed by EMC blocks, special sealing blocks with conductive elements and a stainless steel frame. The setup of E-MCT is very simple. Assembly is therefore also easy; compared to the basic system of MCT Brattberg, only the cables have to be peeled up to the earth screen.

How does it work?

Protection against EMI

Protection against Electro-Magnetic Interference (EMI) There are magnetic fields around cables and other conductors, which can lead to induction. Lightning strikes or nuclear explosions are also sources of induction. This induction can lead to interfering electrical charges on surrounding cables. This charge on the cables can seriously disrupt the associated equipment. E-MCT protects equipment against such EMI influences by guiding it away to earth via the conduit and thus keeping it completely outside the protected space or cabinet.

The same advantages as other MCT Brattberg products The E-MCT variant of the Brattberg system has all the known advantages of the existing MCT Brattberg. The EMC blocks are also pre-greased.

Controllable, reduces the chance of error during assembly
Tested and certified by virtually all classification societies
25 year warranty if installed according to installation instructions

How does it work?

The EMC blocks of MCT Brattberg contain a tin grounding screen. The blocks make contact with each other via tabs on the outside of the blocks and thus ensure complete EMC protection of the cables to be fed through. In addition to the blocks, the EMC end seals are also provided with an earth screen. These can be recognized by the yellow sticker and/or marking on the blocks.

Grounding & bonding

Grouding & Bonding (G&B) can protect sensitive equipment from static charges and ensure that the equipment is not subject to a serious shock hazard in the event of a lightning strike or electrical failure.

Complete shielding

When a frame is completely filled with EMC blocks, the tin earth screen that is incorporated in each block forms a completely closed screen within the penetration. Through this earth screen the current is conducted away from the cables/sheaths to the frame into the ground.

In order for the cables to make contact with these earth shields in the blocks, a piece of the outer layer of the cable must be stripped down to the cable sheath. The jacket makes contact with the earth screen and thus a safe and certified EMC transit is created.

Tools

MCT Brattberg has developed a tool especially for stripping cables with EMC shielding for the penetrations, so that you always strip the outer layer of the cable in exactly the right place for the penetration. It is essential that the shielding of the cable makes good contact with the shielding in the blocks. In addition, there are also other, non-EMC specific accessories and tools available for installing the penetration as quickly and efficiently as possible.
