Title: Need for Upkeep Of Ladder Cable Tray

The Need For Upkeep Of Ladder Cable Tray
  • FRP stands for Fiber Reinforced Plastic.
  • FRP units have multiple uses in the industrial
  • In fact, fiberglass structures are ubiquitous in
    factories and other industrial establishments.
  • Fiberglass is a composite material containing
    glass fibers and has become a favored material
    for engineers and builders.
  • Modern fiberglass structures are imparted more
    strength and life span through various design
    features by the manufacturers.
  • When it comes to FRP ladder cable trays, the
    maintenance is minimal because they are usually
    made of sturdy materials and simply need to be
    installed correctly for longer use.
  • However, some maintenance tips should be
    remembered for ensuring that the FRP ladder type
    cable trays are kept in the best possible

  • 1. Inspecting the unit
  • Although, FRP ladder type cable trays are
    designed to withstand wear and tear and do not
    require much maintenance, it is recommended to
    carry out inspection of the unit to check for
    maintenance issues which may crop up from time to
  • This is especially true for units used in
    industrial facilities.
  • The inspection does not require the aid of any
    special tool and can be simply carried out
  • The unit needs to be examined for presence of
    dirt and foreign objects.
  • Dirt particles and foreign objects need to be
    immediately eliminated from the unit.
  • There after, a check of all the joints must also
    be made.
  • Loose points at the joints, if present, must be
    tightened in accordance with the instructions of
    the manufacturer.

  • 2. Removing the cables
  • Removing extra cables from the FRP ladder type
    cable tray is useful.
  • This is because removal of extra cables enhances
    the loading capacity of the unit and also
    improves ventilation in the system.
  • Enlisting the assistance of professionals for
    removing the extra cables is recommended.
  • 3. Repair and replacement
  • FRP ladder cable trays can suffer many types of
    damages such as deformed side rails, bend rungs,
    damaged welded points, etc.
  • The damage is detected during inspection.
  • The damage must be repaired as soon as it is
    detected to avoid further damage.
  • The damaged part can either be repaired or
    replaced if the damage cannot be repaired.

  • The above mentioned tips are important with
    respect to proper maintenance of ladder type
    cable trays.
  • Manufacturing
  • Cable trays are manufactured using cold rolled
    steel sections which make them light in weight.
  • They are then hot dipped for toughening.
  • The cable trays can be also be made of aluminum
    or steel apart from fiber reinforced plastic.
  • For metal encased cables, a plethora of cable
    trays categorized as light, medium, heavy and
    heavy duty cable trays are manufactured.
  • For non metal encased cables, ventilated heavy
    duty cable trays which reinforce the cables are
  • The cable trays are designed for all kinds of
    cable such as signal cables, telephone cables,
    multi conductor control cables and power cables.

  • Types
  • With the advancement of technology, the
    industrial plants and construction projects are
    increasingly using complex cables and wires to
    run the various mechanized processes.
  • Consequently, the support system for such cables
    also need to be efficient, adaptable and
  • The modern cable trays meet all such parameters.
  • There many kinds of cable trays available in the
    market suited for diverse needs.
  • Ladder type cable tray is the most common variety
    of cable tray.
  • It does not need transitional support and can be
    used for a long period of time.
  • This kind of tray provides easy access to the
    cables from both its sides and allows air
    circulation for the cables from all the sides.
  • Another type of cable tray is single rail cable
    tray. In this type of cable tray, a single rail
    is present on the middle of the tray with curved
    fingers sitting upright from the rail for
    supporting the weight of the cables.

  • This kind of cable tray is suitable for low
    voltage cables.
  • Yet another type of cable tray is solid cable
    tray which does not allow ventilation but
    efficiently protects the cables.
  • The cable trays are robust in construction,
    resistant against corrosion and flame and are not
    affected by UV rays.
  • They meet all the industry standards. The
    material of the cable tray to be installed
    depends upon the local building code requirements
    and the budget of the owner.
  • The electrical load capacity of the tray is also
    an important factor.
  • Benefits
  • Cable tray protects the cables and wires present
    in it.
  • The wires are also kept in an organised manner
    in the tray which makes it easy for electricians
    and other maintenance professionals to detect and
    rectify wiring related problems.
  • The tray also protects the maintenance personnel
    and installers against electric shocks.
