Overview

Fiberglass reinforced plastic (FRP) anti-corrosion cable bridge or tray is made of glass fiber, epoxy resin and other special materials, it has reasonable mechanical structure, light weight,high strength, strong corrosion resistance, flame retardance, aging resistance and good insulation performance, it can be used in a large range of temperature and the environments of high humidity, heavy acid and or heavy alkali.

The service life is 5-6 times of the steel bridge, the installation distance of one ton of FRP cable bridge or tray is 1.5 times of the steel bridge with same specification and same weight.

FRP cable bridge can be overhead laying; erected under the beam or floor slab,can be fixed laterally by indoor and outdoor walls, posts, tunnels, cable trench walls., can also be installed in the open air.

A complete FRP cable tray is composed of straight run, horizontal bend, horizontal tee, horizontal cross, straight reducer, left reducer, right reducer, vertical outside bend, vertical inside bend connected with splice plates, clamps, brackets, etc.

COMPANY PROFILE:

At FIBRETRAY is known for the quality performance of its fiberglass products be it Cable Trays, Street Light Poles, Ladders, Enclosures, Cable Cleats, Cable Supports, Gratings, Handrails.

It is a company promoted by a group manufacturing industrial electrical and instrumentation products for last three decades, specially designed for the use in critical environment.

Fiberglass products were specifically developed due to demand from the valued wide client base.

FIBRETRAY Cable Tray provides reliable cable support in corrosive application. Both polyester and vinyl ester resin systems are available & all components incorporating U. V. stabiliser and a surfacing veil to resist corrosive atmosphere. The cable trays manufactured by us are from pultruded sections / profiles of fiberglass, this pultruded sections help in reducing cost, achieving quality, perfection for optimum performance of the tray.

At FIBRETRAY we have in house facility of producing pulruded sections as well as other accessories with multiple production lines. We at FIBRETRAY produce Cable Trays, as well as molded & metered fittings as well as other accessories like coupler plates, struts, and many more. From power plants to fertiliser industries, paper mills to refineries to laboratories, sound electrical design requires an adaptable cable support system that is reliable. Above all durability and resistance to corrosion lead to lower costs during the life of installation.

CORROSION RESISTANCE OF RESIN SYSTEM

Two standard composites resin systems are available. For most of the application polyester fire retardant (FR-P) is widely used. A vinyl ester composites fire retardant resin system (FR-VE) is used where strong acide (like hydrochloric acid), strong alkalis (like Caustic Soda), organic solvents and halogenated organic conditions exist. fibreglass cable trayincorporates a synthetic veil on the surface of all structural shapes which causes a resin rich layer which enhances corrosion protection. An abbreviated guide can be provided on request to assist in the selection of the proper resin system for individual application.

Intallation Notice

  1. Each ends of cable trays should be connected by 6 holes when the height is 50-100 mm; when their height is 150-220 mm, holes should be 12.
  2. Support distance: it should not be more than the support distance and load capacity allowed by load curve.
  3. Width of cable trays: some remarkable room should be served when you choosing the cable trays width, in order to add cables in the near future.
  4. Laying separately: when electric cables and controlling cables are few, they could be laid in the same cable tray, as long as they are laid separately by clapboard.
  5. Fixing cables: when collecting cable trays are laid horizontally, connections among trays should be set on 1/4 of skip distance, horizontal cables should be fixed every 2 meters, and vertical cables should be fixed every 1.5 meters.
  6. Cable trays device should have another grounding equipment.
