FRP Cable Tray

What Is FRP Cable Tray?

Fiber Reinforced Polymer (FRP) cable trays, thanks to their superior characteristics over traditional materials like steel, are made from fiberglass-reinforced plastics. They come in two varieties: ladder-type and channel-type cable trays. With advantages like lightweight, high strength, good corrosion resistance, and flexible installation, they’re particularly well-suited for use in challenging environments.

  • Polyester Resin (Widely Used): Widely used in industry and combined with UV-resistant additives, it meets the requirements for general conditions.
  • Vinylester Resin: Superior in terms of corrosion and heat resistance.
  • Epoxy Resin: Excellent for insulation performance, especially in electrical power projects.
  • Phenolic: Notable for its extremely low smoke and toxicity properties.
  • Lightweight & Easy Installation: Streamlines the setup process, reducing labor and time.
  • Chemical & Corrosion Resistance: Ensures durability in harsh environments.
  • Electrically Non-Conductive: Offers safety in environments where electrical insulation is crucial.
  • Fire Resistance: Enhances safety by reducing fire risks.
  • Low Maintenance: Minimizes upkeep efforts and costs over time.
  • High Load Capacity: Capable of supporting substantial weights, ensuring reliability.
  • UV Stability: Maintains integrity and appearance when exposed to sunlight.
  • Offshore Platforms: Fiberglass cable trays are widely used on offshore platforms because the environment there is highly corrosive due to seawater and extreme weather conditions. The corrosion resistance of fiberglass cable trays makes them an ideal choice for such environments.
  • Chemical Plants: In chemical plants, it’s common to encounter irritating chemicals and corrosive substances. Fiberglass cable trays offer a reliable solution for cable management with no risk of corrosion.
  • Oil and Metal Refineries: These environments often involve exposure to corrosive substances and high temperatures. The corrosion resistance and heat tolerance of fiberglass cable trays make them suitable for oil and metal refineries.
  • Water Treatment Plants: The humidity and chemicals in water treatment plants can cause metal cable trays to corrode. Fiberglass cable trays, with their excellent corrosion resistance, are the preferred choice in such environments.
  • Telecommunications: For low voltage and telecommunication cables, fiberglass cable trays provide a lightweight and durable solution, supporting cables over short spans and ensuring effective cable routing.
  • Construction and Residential Applications: Thanks to their lightweight and high strength, fiberglass cable trays are used in construction and residential settings to protect cables from heating, rainwater, and corrosive elements.
  • Industrial and Commercial Installations: Fiberglass cable trays are widely used in commercial and industrial sectors for their structural advantages and easy installation, managing multiple wires.
  • Power Plants and Other Facilities: In power plants and similar facilities, fiberglass cable trays support and organize cables and wires, including high-voltage power cables, control cables, and fiber optic cables, providing a reliable solution for power distribution and communication.
  • Offshore and Coastal Locations: The durability and corrosion resistance of fiberglass cable trays make them highly suitable for challenging marine and coastal environments, where they can withstand harsh corrosive conditions.
Fiberglass trough type cable tray

Fiberglass trough type cable tray

A fully enclosed type of cable tray, is most suitable for laying out computer cables, communication cables, thermocouple cables, and other control cables for high-sensitivity systems. It offers good protection against electromagnetic interference and in corrosive environments.
