FRP (Fiber-glass reinforcing Plastic) cable trays are considered over the traditionally used materials owing to their several benefits in the recent days. Why don’t you use the FRP cable trays for your upcoming project? FRP cable trays are made up of non-metallic base which obviously makes them resistant to corrosion and abrasion and less prone to electric shock hazards, along with that they have a long durability. The FRP trays pass through a series of tests to meet the NEMA FG-1 criteria and other self-distinguishing tests before they hit the market.
Structureand Mechanism of FRP Cable trays
An FRP Cable tray is made up of several items clubbed together like straight runs and horizontal bends, horizontal tee, horizontal cross, straight reducers, left and right reducers, vertically outside and inside bends which are connected with splice plates, clamps, brackets and lots more. All these raw material pass through the process of Pultrusion. In this process all the raw materials are pulled by continuous heated dye of steel with a pulling device, which transforms and moulds them into the desired item. Then they are cut into the desired lengths and are sent to the market.
Benefits of FRP Cable trays
Undoubtedly, these cable trays can survive in harsh conditions owing to their several beneficial properties, listed below,
- Resistant to Corrosion and abrasion – Being non-metallic, they are completely rust free which means they have a long life span. Available in different colours, they enhance the look as well.
- No shock – Being non-metallic, they are non-magnetic, shock proof and fire retardant. They are UV and salt water resistant as well.
- Strong and durable – Being light weight, they can be installed easily and almost everywhere, especially in marine and coastal environment. Also, no extraordinary tools or work permit are required for the installation of these cable trays.
- Stability – They can survive high temperatures and can disperse heat faster. Also, they can withstand high load bearing cables. They do not shrink or swell, which makes them dimensionally stable.
- Lighter – They are light weight as compared to the traditional ones and can be easily installed and cut as per requirement.
- Shapes – There are many shapes of FRP Cable trays like, ladder type cable trays, perforated cable trays, channel cable trays and large life span cable trays.
- Low maintenance – Hardly any maintenance is required for these trays. They just need to be installed and they serve you for long!
Usage of FRP cable trays
These FRP cable trays are used extensively to support power cables, inside and outside computer server rooms, chemical plants, purification plants, oil and gas industries and to support computer and controlling cables, building construction, radar industry, building construction, metal refineries across the globe.
Shapes of FRP Cable trays
- Channel type Cable tray–These cable trays are designed with I-beam rails and are fully enclosed with a cover and ventilation points, which ensures safety from dust, water and any falling object.
- Ladder type – These are made by joining two longitude channels with horizontally supporting rungs. They have large space and offer ventilation as well, which makes them perfect for paper mills, power plants, oil and gas industries and any exterior environment work.
- Perforated type – These cable trays are designed with holes or perforation in the sideways and bottom of the trays, mainly for electricity distribution in power and signal cables. The holes allow sufficient ventilation, while the steel cable trays are designed such that they can support light, medium or heavy cable lines, passing through them.
So go ahead and choose the FRP Cable Tray for your next project of your choice from the many in the market. Just ensure from the store or manufacturer, that you choose the one which has passed the various tests like surface burning and precast flammability.
