Kabeldoorvoeringen spelen een cruciale rol bij het waarborgen van de veiligheid en integriteit van elektrische en communicatie-installaties in potentieel explosieve (Ex) omgevingen. Er zijn meerdere redenen waarom Ex kabeldoorvoeringen belangrijk zijn in potentieel explosieve atmosferen:
1. Hazardous Atmospheres: Potentially explosive atmospheres exist in various industries such as oil and gas, petrochemicals, mining, pharmaceuticals and manufacturing, where flammable gases, vapors or combustible dusts may be present. These environments pose a significant risk of explosion if proper precautions are not taken. Cable transits provide a means of sealing and protecting cable transits, preventing the spread of flames, gases or hazardous substances from one area to another.
2. Protection against fire: In case of fire or explosion, cable glands with the appropriate sealing mechanisms act as fire-resistant means. They prevent the spread of fire through cable penetrations and contain it within the specified compartments. By preserving the integrity of fire barriers, cable transits help protect personnel, equipment and infrastructure from the devastating effects of fire.
3. Electrical safety: Cable transits contribute to electrical safety in Ex areas. They ensure proper routing and organization of cables, minimizing the risk of electrical faults, short circuits and arc flashes. MCT Brattberg also has filling that is both ATEX/IECEx and EMC certified. This ensures that an EMC shield is created, so that all equipment is also protected against all forms of EMI. More information about this can be found on the page for EMC cable transits.
4. Compliance with regulations: Various international standards and regulations, such as ATEX and IECEx, prescribe the use of certified cable entry systems in Ex environments. To meet safety requirements and protect personnel and assets, compliance with these regulations is crucial. The transits of MCT Brattberg are both ATEX and IECEx certified.
5. Maintain system integrity: Cable transits ensure the integrity of Ex-rated enclosures by effectively sealing cable transits. They prevent the ingress of water, dust or other contaminants into sensitive environments, such as control rooms or electrical cabinets, which can compromise equipment performance and reliability. By maintaining the integrity of these enclosures, cable transits help prevent equipment failure and system downtime.
6. Ease of installation and maintenance: Cable transits designed for Ex areas are often designed with ease of installation and maintenance in mind. The penetrations of MCT Brattberg are numbered per block and can therefore be checked (also afterwards). This facilitates troubleshooting, repairs and future adjustments to the transit itself and the systems from which the cables originate.
Cable transits are an essential safety system in Ex environments because they guarantee the safety and integrity of electrical installations. Due to the fire-retardant properties and the prevention of the spread of hazardous substances, Ex cable transits play a crucial role in protecting personnel, equipment and infrastructure in potentially explosive atmospheres.
