Long Span Ladder Cable Tray 150mm-900mm Width 75mm-250mm Depth for Power Distribution

Long Span cable ladder for Power Distribution is the type U route built for the main power spine of a plant or a utility network, where large cross section feeders run in parallel over long distances and the support system must hold its geometry between widely spaced hangers.

The type U profile uses deep side rails in carbon steel, stainless steel or aluminum, with 75 mm to 250 mm height, side rail thickness of 1.5 mm to 3.0 mm and rungs of 2.5 mm to 5.0 mm at 225 mm, 300 mm or 450 mm pitch. Widths of 150 mm to 900 mm accommodate everything from a four core 240 mm2 feeder to multi circuit trays in a substation.

The U section is what delivers the span. A deeper, closed form rail resists torsion and lateral buckling, so support spacing of 3 m to 9 m can be justified with a calculation rather than assumed from a table. That reduces the number of hangers in a switchyard or a turbine hall, where every anchor is a cost and a penetration.

For power distribution the electrical details matter as much as the steel: couplers and bonding jumpers maintain a continuous earth path, the ladder accommodates single core cables without the hysteresis heating that steel can cause when aluminum is used, and covers or partitions can separate power from control cable on the same route.

BENDIN produces the type U family at up to 50000 m per week with 180 staff and thirty years of power project experience, exporting 60 to 70 percent of output to utilities and EPC contractors. Each order carries dimensional records, coating test results and, where specified, third party inspection reports.

Minimum order 100 m, 15 to 25 working day delivery, 10 to 20 USD per metre, carton, box or wooden case packing, terms L/C, D/P or T/T. Send the single line diagram and the cable schedule and we will return support spacing, load deflection and the earthing arrangement.

BENDIN holds ISO 9001 quality certification and issues CE Declarations of Conformity. The standards above state the design and test basis of this product; third party test reports or national approvals are supplied on request and are not implied unless confirmed in the contract.

Dimensions, rung spacing and surface treatment are produced to project drawings. Load and deflection calculations are issued for spans above 3 m.

Q: Why choose a type U profile for power distribution?
A: The closed channel rail resists torsion and lateral buckling, which is what allows wide hanger spacing in a switchyard or turbine hall.

Q: How is the earthing path maintained?
A: Couplers and bonding jumpers are supplied for every joint, and continuity is verified against the IEC 61537 clause 10 requirement.

Q: Can power and control cable share the route?
A: Yes, with partitions or a separate tier. We supply dividers so power and control cable remain separated as the design requires.

Q: What is the minimum order?
A: Minimum order 100 m, delivery 15 to 25 working days, prices from 10 to 20 USD per metre.
