Breite der Kabel-Leiter-100mm mit flacher Abdeckung und UL, CER, NEMA, ISO, SGS

Ladder Cable Tray provides:
a. Solid side rail protection and system strength with smooth radius fittings and a wide
selection of materials and finishes.
b. maximum strength for long span applications standard widths of 6,12,18, 24, 30, and 36
 inches
c. standard depths of 3, 4, 5, and 6 inches
d. standard lengths of 10, 12, 20 and 24 feet
e. rung spacing of 6, 9, 12, and 18 inches
 Ladder cable tray is generally used in applications with intermediate to long support spans 12 feet to 30 feet.

Advantage of ladder tray:

Full free air rating of cables, results in smaller conductors vs. conduit

Greater fill volume allowed, results in less space

Used in all locations except elevatorshafts (the only prohibition on cable tray use)

Used as an equipment grounding conductor

Less stress on cables during installation and operation

Increased safety, no moisture condensation problems nor transmission of corrosive or explosive gases, as with conduit

Simplified maintenance with the flexibility of adding or changing circuits

Simplified engineering and construction. Add, change, modify more easily

Used with other wiring methods

Longer support spans up to 55'
