Standard distance of cable tray support

. The standard refers to cable fill as pile-up which changes according to runway width. Cable tray systems design shall comply with NEC Article 392 NEMA VE 1 and NEMA FG 1 and follow safe work practices as described in NFPA 70E. For purposes of selecting a suitable tray this weight should be rounded off to the next higher NEMA working allowable load.

Support of cable tray shall be located within 2ft 600mm max of each side of expansion splice plates. Flexible Systems For flexible systems where the cable is not directly fixed to the support system for example a J-hanger installation calculations need to be undertaken to determine the required distance between the cable support positions to achieve a set deflectionoff-set. In most UK steel construction the allowable deflection at safe working load is L200 for beams and L180 for cantilevers based on UK steel design standards.

Deflection limits are usually expressed as a proportion of the support span L or the product width W. Standard widths of 3 4 and 6 inches in metal systems and up to 8 inches in nonmetallic systems. The Telcordia standard was designed for cable runway limiting a span to 5 feet in most cases but allowing 6-foot spans in certain exceptional cases.

One or more spans IEC 61537 73i For installations with more than one span it is important to notice that the loading capacity is not the same form one end to the other. Hold-down clips and support fitting shall be provided at each support point. This is the total weight of cables in the tray.

Support Spans-- Support span is the distance between the supports. Wire Mesh Cable Tray Trays shall be supported at a maximum span of 25m by trapeze wall floor or channel mounting methods and will not exceed maximum loads as specified by the manufacturer. The NEMA standard support spans are based on 8 12 16 and 20.

60 mm side height standard support with 15 m 3 110 mm side height standard support width 35 m 17. Support Load Calculation Per IEC 61537. Horizontally running cable trays shall be supported at an interval of 2000 mm without causing any permanent deformation.

Channel cable tray is used for installations with. Expansion guides should be used at each support point except where the tray is hung with rods. Cable Trays will have rung spacing of 250 mm and side runner of 100 mm.

1An economical support for cable drops and branch cable runs from the backbone cable tray system. For specific loading go to the interac-. A Light Duty Non-Return Flange.

An economical support for cable drops and branch cable runs from the backbone cable tray system. Standard widths of 75100 and 150 millimeters in metal systems and up to 200 millimeters in. Vertically running cable trays in cable risershaft shall be supported at an interval of 1000 mm.

Evenly Distributed Load 2 X Point Load Support Distance. IEC-61537 This international standard specifies requirements and tests for cable tray systems such as. INSTA-trays 60 mm side height support width up to 30 m 29 Luminaire support tray 50 mm side height support width up to 30 m39 Trellis tray 60 mm side height standard support width 15 m 43.

For example for runway that is 6 to 12 inches wide the maximum cable fill is the width of the runway. Cable trays shall be supported by mild steel galvanized brackets at regular intervals of 12mm maximum and at 255mm from bends and tees. Cablofil wire mesh tray and sup-ports are designed to support any cable load allowed by the NEC when supports are spaced on 8 spans.

For Cable Tray InstallersThis publication is intended as a practical guide for the proper installation of cable tray systems. Standard length of 10 12 20 and 24 feet. Gauges shall be a minimum of 10mm for tray up to 225mm 12mm between 225mm.

Standard depths of 11inches in metal systems and 1 1 18 1 5 and 2 316 inches in nonmetallic systems. Cable supports should be applied either side of the bend.
