What is MCT cable tray

Page Content

MCT (Multi Cable Transit) systems provide a secure, sealed method for routing multiple cables through cable trays or barriers while protecting against fire, water, gas, and environmental hazards.

Overview of MCT Systems

MCT systems are designed to allow multiple cables to pass through a single opening in walls, floors, or cable trays while maintaining the integrity of the barrier. They are widely used in industrial, marine, offshore, and hazardous environments to ensure safety and compliance with standards such as ATEX and IP ratings . Unlike traditional cable glands, MCTs can accommodate multiple cables in a single frame, reducing installation time and improving sealing quality .

Components

An MCT system typically consists of:

Frame: The housing that holds all modules and components, which can be made of steel, stainless steel, or other materials, and may be bolted or welded to the structure .
Sealing Block Modules: Adaptive blocks that hold individual cables. The central core and layered sheets can be peeled to match the cable diameter, ensuring a tight fit .
Stay Plates: Placed between rows of modules to prevent module pull-out and maintain alignment .
Wedge or Compression Unit: Applies pressure to the assembly, creating an airtight and watertight seal .

Benefits in Cable Trays

Sealing and Protection: MCTs protect against fire, smoke, water, gas, chemical liquids, and pressure at cable penetration points .
Flexibility: The modular design allows adaptation to cables of different sizes and quantities, making it ideal for complex cable tray layouts .
Compliance: Maintains IP ratings and ATEX certification, which is critical for hazardous areas .
Efficiency: Reduces installation time compared to multiple individual cable glands and ensures consistent sealing quality .

Installation Considerations

Proper alignment and tightening of the sealing block and wedge are essential to guarantee airtight and watertight performance .
Frames should be bonded to the grounding system to ensure electrical safety .
Cable markers can be installed at the entry point for identification and maintenance purposes .

Applications

MCT systems are commonly used in:

Cable trays and industrial cabinets for power plants, manufacturing facilities, and offshore platforms .
Hazardous areas where fire, gas, or water ingress protection is required .
Marine and offshore projects where environmental conditions are harsh and reliability is critical . In summary, using MCT in cable trays provides a safe, flexible, and efficient solution for managing multiple cables while maintaining barrier integrity and compliance with safety standards.
