 | CABLE TRAYS, STRAIGHT RUNS
GENERAL INFORMATION
PULLTECH Cable Trays are fabricated with Fiberglass Reinforced Polyester (FRP) by means of the continuous process called Pulltrusion.
| PULLTECH cable trays are assembled starting with a Z or E profile of high mechanical strength and a square tube profile. There are two models, a Standard (EST) model, which is 100mm high, and a Heavy Duty (EHD) model, which is 127mm high, both in lengths of 3m and 6m. The square tube profiles are the spacers on which the cables lie, and the maximum width of a cable tray is 600mm. Longitudinal spacing of these square tubes is 300mm.
ADVANTAGES High mechanical resistance, a result of its fabrication process
High chemical resistance, provided by the polyester utilized
Resistance to fire (optional) and elevated temperature
Resistance to UV rays
Electrically non-conductive
Excellent appearance, with colour incorporated
Ease of installation due to its low weight
