Definitions

  • the invention relates to a fire protection system for carrying elements for cables, wires, tubings, pipes or the like. More specifically it relates to a modular fire protection system for carrying elements for cables, wires, tubings, pipes or the like. Furthermore, the invention relates to a fire protection layer for a carrying element for cables, wires, tubings, pipes or the like.
  • Cable tray systems are commonly used for organising tubing, electrical cables and wires and instrumentation in industrial buildings and constructions, where there might be a higher risk of fires. To ensure integrity of the cables and wires, it is therefore advantageous to protect the cable trays against overheating or fires, or at least reduce the risk of the cable trays overheating or catching fire, or at least increase the time before the cables and wires are overheated or a fire spreads to the cable trays.
  • the fires to protect cable trays from may be cellulosic or standard fire, hydrocarbon or pool fire, jet fire, or high-heat-flux jet fire.
  • Conventional methods for protecting cable trays against fire include wrapping the cable trays with fire retardant material or a fire resistant material, painting the cable trays with a fire retardant paint or a fire resistant material, or enclosing the cable trays with a ceramic or an epoxy box.
  • the invention has for its object to remedy or to reduce at least one of the drawbacks of the prior art, or at least provide a useful alternative to prior art.
  • the invention relates to a modular cable tray system comprising
  • the carrying element for a cable, the carrying element comprising a base and an upper side opposite the base, and at least two opposing side walls, each side wall having an outer side;
  • first and a second fire protection layer each comprising a surface corresponding to the base of the carrying element, and at least two opposing side edges, wherein the first fire protection layer is configured for enveloping, when in use, in a snug fit, at least the base of the carrying element and a portion of the side walls, and the second fire protection layer is configured for, when in use, covering at least the upper side of the carrying element and a portion of the side walls and
  • the first fire protection layer may be a bottom fire protection layer.
  • the second fire protection layer may be an upper fire protection layer.
  • the upper side of the carrying element may be open, or it may be covered by a lid.
  • the first and the second fire protection layers envelop the carrying element to protect the carrying element, and any elements it may carry, from a fire.
  • the first and the second fire protection layers fit snugly onto the carrying element and are held in place by the fastening mechanism.
  • the first and the second fire protection layers are easy to install onto the carrying element.
  • the modular cable tray system may be assembled at the site, or pre-assembled before installation at the site. Because the assembly of the modular cable tray system is easy to perform, the quality of the fire protection of the modular cable tray system is ensured.
  • the cable tray system may also be realistically tested in different fire scenarios, as the components and the assembly of the modular cable tray system in the test scenarios may be the same as the components and the assembly installed on site.
  • the advantage of the first and the second fire protection layer having a surface that corresponds to the base of the carrying element, is that the resulting cable tray system is modular. That is, a fire protection layer can be customised to different carrying elements for cables, regardless of the shape and size of the carrying element.
  • first and second fire protection layers may not be identical.
  • first and second fire protection layers may be substantially identical, i.e. they may have substantially the same size and form but may still comprise minor differences, so that each of the fire protection layers covers half the height of each side wall of the carrying element. This may simplify the manufacturing as the first and the second fire protection layers may be made identical or substantially identical. Furthermore, the first and the second fire protection layers may in this case be easier to install onto the carrying element. In other examples the first and the second fire protection layers may be identical.
  • the carrying element may be a cable tray, a cable channel, a cable trough, a trough cable tray, a ventilated cable tray, a cable ladder, a ladder tray, etc.
  • the carrying element may have any shape or size, such as a straight carrying element, an inside riser carrying element, an outside riser carrying element, an elbow carrying element, a tee-piece carrying element, a reducer carrying element, a bender carrying element or a cross-piece carrying element.
  • the carrying element may be made of a metal such as stainless steel, or a fibre plastic material, or other suitable materials.
  • fire protection layer must be interpreted as a layer comprising a passive fire protection material that slows or impedes the spread of a fire from one side of the layer to the other side or retards the increase of the temperature on one side of the layer if the temperature increases on the other side of the layer.
  • protection from fire by the fire protection layer, it is meant that the fire protection layer reduces the risk of a fire spreading from one side of the layer to the other side, or increases the time it takes before the fire passes from one side of the layer to the other side, or at least increases the time it takes before the temperature on one side of the fire protection layer increases if the temperature increases on the other side of the layer

  • the flange extends continuously along the side edges 350. The flange makes it easy to install the fire protection layer 31, 32 onto the cable tray 20 because the flange is easily aligned with one of the catches 450.
  • the flange of the first, second and fourth fire protection layers 31, 32, 34 may in another embodiment (not shown), be extending outwards from the side edges 350, so that the flange may form a snap-fit configuration with corresponding catches (not shown) on the cladding.
  • the area of the surface 360 of the fourth fire protection layer 34 is larger than the bracket 900, to reduce the risk of a heat bridge to occur between the support structure 60 and the carrying element.
  • the first, second and fourth fire protection layers 31, 32, 34 expand when exposed to heat, such as from a fire.
  • the first, second and fourth fire protection layers 31, 32, 34 are provided with first, second and fourth spacers 311, 321, 341 respectively.
  • the first, second and fourth spacers 311, 321, 341, when in use, create first, second 312, 322 and fourth (not shown) expansion spaces between the first fire protection layer 31 and the base 200 of the cable tray 20, between the second fire protection layer 32 and the lid 230, and between the fourth fire protection layer 34 and the base 200 of the cable tray 20.
  • the third fire protection layer 33 is not provided with spacers in the example shown in figure 9, however, in another example (not shown) the third fire protection layer 33 may be provided with spacers.
