When it comes to powering, automating and protecting facilitiesꟷfrom factories and petrochemical plants to data centers and high-risesꟷthe right cable makes all the difference. Among
Several types of tray are used in different applications. A solid-bottom tray provides the maximum protection to cables, but requires cutting the tray or using fittings to enter or exit cables. A deep, solid enclosure for cables is called a cable channel or cable trough. A ventilated tray has openings in the bottom of the tray, allowing some air circulation around the cables, water drainage, and allowing some dust to fall through the tray. Small cables may exit the tray throug
Since cable trays do not fully enclose cables, which would be the case with cable raceway or ducts, tray cable must conform to strict requirements
Dividers or Partitions: Where cables must be close due to space constraints, using a metal partition between power and control trays can help prevent interference.
