Cooper B-Line

Cable Management: Wire Mesh Cable Tray System

Cooper B-Line’s Wire Basket Cable Tray Systems is an economical solution for those installations where fast and easy assembly is a priority and offering proper ventilation for electrical cables. The Cooper B-Line innovative design (patented) gives the cable tray a higher load bearing capacity and rigidity allowing the installer to introduce more cables inside the tray.

The standard 50mm x 100mm wire mesh pattern is designed for maximum flexibility, allowing for easy field cutting, bending, assembly and convenient cable drop outs.

Fast - Adaptable – Economical

WIRE BASKET CABLE TRAY SYSTEM

Advantages:

Cooper B-Line wire tray is a good and economical solution for installations that don’t need high load bearing capacity. It is manufactured in 3 metres lengths with three different heights, 35mm, 65mm and 105mm.

  • It offers maximum ventilation and cleanliness
  • Its innovative design gives competitive advantages such as:
  • Higher bending resistance
  • Higher load bearing capacity
  • Excellent aesthetic quality
  • Faster and easier assembly
  • With a simple cut to the wires you can shape the basket tray making angles easy to construct
  • Cuts must be made with asymmetrical cut pliers
  • The cut must be done as close to the wires intersection as possible, to obtain a clean cut and to maintain proper assembly

FINISHES

Electro-Zinc

The coating process used is electrolysis, achieving a standard ISO 2.081. This superficial treatment takes place after forming the basket and the zinc thickness achieved is between 8 and 12 microns.

Hot Dipped Galv

This process consists in the dipping of the pieces in a melted zinc bath at 450 ºC (standard UNE EN ISO 1.461:99). This superficial treatment takes place after conforming the product and the zinc thickness obtained depends on the thickness of the cable tray, and it’s between 45 (for thicknesses thinner than 1,5mm and 85 microns for thicknesses over 6mm.

Epoxy Polyester

Procedure consisting in the application of epoxy polyester hybrid resins and later polymerising at 185-195 ºC for 15 minutes. The zinc thickness achieved is between 60 and 80 microns. This coating is applied on the pre-galvanised steel or the “black” steel.

Stainless Steel AISI Type 304

Stainless steels are carbon steels alloyed with chrome, nickel, manganese and molybdenum. The most usual one is AISI 304, being ideal for chemical, food and maritime industries, or were a high degree of corrosion resistance is required.

STRENGTH

At Cooper B-Line we have carried out several tests to the cable tray to know the load bearing capacity.

The calculation hypothesis adopted, as we can see in the design below, has been a three metres long cable tray, with the load distributed all along the tray and with a distance between supports of one, one and a half and two metres.

All tests have been made following the directions of the European Normative EN 61537 that regulates the cable tray and cable ladder systems for cables management. This normative informs that the maximum deflection allowed for a cable tray is 1/100 of the length.
