With the growing dependence on computers, communication and control equipment the problem of sensitivity to interference becomes more apparent, given the vulnerability of modern electronic equipment.
The vulnerability can lead to expensive interruptions in production, communication and process control. Consequently, it is essential that two of the most important concerns with modern electronics must be to create a safe and secure environment and to eliminate the risk of interference.
Cable and Pipe Penetrations exist whenever services are routed through walls, floor, decks or bulkheads. In an
emergency situation these penetrations could allow the passage of hazardous such as fire, water and gas. The unique MCT Brattberg System has been approved by all leading Marine and Civil Authorities as a certified
method of sealing such penetrations. The MCT Brattberg system is a Multipurpose seal designed to allow penetration without compromising the security of the construction. Each and every cable and pipe is lead through a frame by its own pair of halogen free module blocks which are then sealed by the use of a compression system.
Historically, protection of buildings, personnel and equipment from lightning was achieved by the use of lightning conductors. These measures, however, are inadequate as they provide protection from fire and personal injury only; to eliminate the Electromagnetic Interference (EMI), sometimes known as electronic smog, protection must be more specific. The protection is achieved by a means known as Electromagnetic Compability (EMC) giving both external and internal interference protection. The MCT Brattberg system is available in a specific E-version which include both the EMI and EMC-version. Around and in close proximity to every electrical conductor exist a magnetic field. This magnetic field generates/interferes with the current flow, known as induction.
Such induction fields can easily cause important information to be destroyed and, in extreme cases, affect the electronic equipment. The ability of any cable to intercept such energy depends on how and where it is installed, on its connection to other units and on its construction. The cables screening properties, therefore depend closely on the cable shielding. The cable screen is able to dissipate and absorb magnetic interference fields, therefore protecting its core conductor. These electromagnetic interference pulses can be discharged from screen to earth.
The MCT E-Series contains a sprung copper sheet which prevents transfer of interference in the cable. Consequently, every MCT E-Transit also works as an extended wall screen.
As with all MCT Brattberg products, the MCT Brattberg E-system comprises of a modular sealing system installed in a frame and sealed by compression system. Uniquely, however, the MCT E-system contains features which ensure earth continuity and screening through the penetration. Frames are welded into the wall structure to give earth bonding. For round penetrations a steel sleeve is welded to the structure prior to the installation of the RGP transit. MCT E-Blocks have the facility to screen and earth cables and pipes when installed in such frames. Stayplates are used to key blocks into frames and aid continuity between module blocks. The presswedge whilst compressing the system, give the facility to allow full screen and earthing bond.
The E-MCT blocks consists of 2 different materials:

In high-risk environments, such as explosive hazardous areas, “Putting Safety First” is our number one priority. This is the reason why MCT Brattberg’s products are installed globally.See more
