Cable Enclosures & Encasements

Features of Durasteel Cable Enclosures

• 2 and 3-sided systems fixed directly to the concrete soffit, wall or slab
• 4-sided system suspended on a support system
• Provides either 2-hour or 4-hour fire protection in both directions
• Can include demountable access panels for cable maintenance
• Cables can either be self-supported directly by the Durasteel enclosure or on their own trapeze support system and cable ladder/tray which is then fully encased by an independent Durasteel enclosure
• Thermal shock protection to protect from firemen’s hoses
• Flexibility to transition between two, three and four-sided systems in both horizontal and vertical arrangements, to accommodate for:
  • The cable route
  • Cable bend radiuses
  • Passthrough compartment firewalls
  • Compartment concrete floor slabs
  • Cable weight load (omitting the need for a cable tray if installed directly on a 4-sided system)

There are two fundamental Durasteel cable enclosures systems which are used for different scenarios and requirements.

Integrity-Only Cable Enclosure

• Single board system fixed to skeletal framework providing integrity-only fire protection
• Only used if the cables are not critical to life-safety systems
• Ideally suited for:
  • Data cables/communication cables
  • Low/high voltage cables
  • Busbars (carries electricity to cabinets)

Integrity & Insulation Cable Enclosure

• Two board system fixed to skeletal framework to insulate cables
• Can include intumescent grilles to allow for heat dissipation
• Ideally suited for:
  • Life-safety cables
  • Any interior building element designed to evacuate people in an event of an emergency (means of egress)
  • Circuit breakers
  • Electricity generation
  • Fire alarms
  • Life-support systems
  • Telecommunications
  • Signal and control systems
  • Platform detection to control doors and automatic train stop systems
  • Air traffic control
  • Radio systems
  • Sprinklers
  • Smoke alarms
  • Smoke extraction fans
  • Transformers
