CABLE TRAY SYSTEM
Cable ladders are ideal to install large volumes of heavy duty power cables. The long rung spacing
means full free air rating of cables. Higher current fl ow can be achieved at the same cable cross-
section. Overheating and consecutive damaging of cables is avoided. The new shape of the side
rail allows higher cable loads at similar support spans, the continuous perforation in the siderails
guarantees easy mounting of fi ttings. Cables can be installed and fi xed to the rungs using appro-
priate yoke clamps. Niedax Cable ladders can be slit together to minimize transport and storage
volume needs.
All straight sections of cable tray as well as their corresponding system components (fi ttings, splice plates, covers, ...) are classifi ed by UL in acccordance with NEMA VE 1 for the USA and CSA E22.2 No. 126.1 for Canada.Please add an ‚X‘ after the fi rst sequence of characters in the part number to get your products labeled for UL conformity (f.e. RLV 60.200 becomes RLVX 60.200 or GRS 110.300 becomes GRSX 110.300).

Cable Ladder Specifi cations:
A. CABLE TRAY DESIGN1. Cable Tray shall be made of straight sections, fi ttings and accessories as defi ned in the latest NEMA standards
per NEMA VE-1. Standard cable trays shall be UL classifi ed as equipment grounding conductors.
B. MATERIAL1. Pre-galvanized steel. The structural quality of the steel shall meet the minimum yield and tensile strength of the
ASTM standards (ASTM A 653) with G 90 coating thickness. All cable trays to be labeled for material identifi cation purposes.
2. Hot dipped galvanized steel. All trays to be hot-dipped galvanized in accordance with ASTM A123. All trays to be labeled for material identifi cation.
3. Stainless steel. All trays are to be constructed of AISA type 304 or 316 stainless steel. All trays to be labeled for material identifi cation.
C. TRAY TYPES 1. Ladder cable tray. Ladder shall consist of two side-rails with rungs riveted to the bottom fl ange of the side-rails.
Rungs shall be spaced 8” or 12” (200 or 300 mm) on center. Rungs shall not protrude below the bottom of the side-rail.
D. TRAY SIZE 1. Height: Ladder shall have an overall height of 4” (100 mm).
Minimum load depth shall be 3.5” (90 mm).
2. Width: Widths shall be 8”, 12”, 16”, 20” and 24” (200, 300, 400, 500 and 600 mm)
3. Length: Length shall be a nominal 10’ or 3 meters and 20’ or 6 meters
E. ACCESSORIES1. Covers. Covers shall be supplied to protect tray cable where needed. Covers will be solid and contain three pair
of turn-bolt locks to secure the covers to the lips of the cable tray, requiring only the use of a slotted screwdriver.
2. Splice plates. Splice plates shall fasten to the outside of the cable tray side-rails and wrap around and snap onto each section of tray. Bolts and nuts are used to fasten to the tray and are included with splice plates. Plates shall not exceed the NEMA VE-1 resistance of 330 micro ohms.
3. Other accessories shall be furnished as required to protect, support, and install a cable tray system. Fittings shall made of the same material as the cable tray whenever possible. Fittings can be of factory construction or also be of a type that allows fi eld constructed fi ttings.
F. LOADING CAPABILITIES1. Cable tray shall meet the load/span class designation in accordance with NEMA VE 1 and CSA E22.2 No 126.1.
Cable tray shall also meet load/span designation in accordance with IEC 61537
G. DESIGN AND MANUFACTURE1. Cable tray design shall be manufactured by The Niedax Group.
