They protect cables from physical damage, such as falling debris, and shield them from harsh weather conditions, including rain and extreme temperatures. This level of protection reduces the risk of electrical hazards. Our outdoor cable trays simplify maintenance. Every project engineer knows the challenge: balancing material cost against long-term corrosion resistance in an outdoor cable tray specification. A conservative choice blows the budget; an optimistic one guarantees premature failure. The mechanical and electrical characteristics, tests, certifications, overall quality management, recommendations mentioned in this technical guide only apply to our own cable management ranges and cannot under any circumstances be transposed to similar or. Is your cable tray system optimized for safety, dependability, space and cost savings? Cable tray (or cable ladder) systems are a popular alternative to electrical conduit systems, as they have an outstanding record for dependable service, design flexibility and cost savings in commercial and. Ladder type cable trays (also called ladder cable trays) are a kind of cable management system formed by two side rails along the length connected by individual rungs forming a ladder-like structure which facilitates easy installation, maintenance and cable ventilation.
