Why Choose The Sun Cable Ladder?
The Sun produces cable ladder systems directly at our factory, helping contractors control quality, cost and delivery schedules. CNC fabrication, laser cutting and automated welding support consistent dimensions across straight lengths, bends, tees, crosses, reducers, couplers and support accessories.
- Reliable performance: material thickness and protective finishes are selected for the required environment and design load.
- Factory-direct supply: clear technical advice and a practical quotation without unnecessary intermediaries.
- Project coordination: we support quantity take-off from drawings and provide the required dimensions for installation planning.
NEMA VE 1 Load Considerations
For a specified NEMA load class, cable ladder selection must consider the design load, support span and test load. The Sun can advise on a suitable ladder configuration after reviewing cable weight, span, installation route and required safety margin.
| NEMA class | Support span | Design load | Test load |
|---|---|---|---|
| NEMA 8A | 2.44 m (8 ft) | 74.4 kg/m | 111.6 kg/m |
| NEMA 8B | 2.44 m (8 ft) | 111.6 kg/m | 167.4 kg/m |
| NEMA 12A | 3.66 m (12 ft) | 74.4 kg/m | 111.6 kg/m |
| NEMA 12B | 3.66 m (12 ft) | 111.6 kg/m | 167.4 kg/m |
| NEMA 16A | 4.88 m (16 ft) | 74.4 kg/m | 111.6 kg/m |
| NEMA 16B | 4.88 m (16 ft) | 111.6 kg/m | 167.4 kg/m |
Important: long-span designs need the cable ladder and its splice joints to be evaluated together. Tell us the support spacing and cable load so we can recommend the appropriate material, rail height, thickness and accessories.
Select the Right Finish for the Installation Environment
- Powder-coated cable ladder: suitable for indoor installations where appearance and colour identification are important.
- Pre-galvanized (GI) cable ladder: an economical choice for dry indoor projects and fast delivery requirements.
- Hot-dip galvanized cable ladder: designed for outdoor, humid, coastal or more corrosive environments.
- Stainless steel 304/316 cable ladder: used where hygiene or corrosion resistance is critical, including food, healthcare, chemical and clean-room facilities.
Cable Ladder Drawings, Fittings and Ordering Information
A complete system includes straight ladder sections and compatible fittings: horizontal bends, vertical bends, tees, crosses, reducers, couplers, covers, clamps and supports. For an accurate quotation, send the required width, side-rail height, steel thickness, finish, length, fitting quantities, support span and project location. CAD drawings or a bill of quantities help us check the routing and calculate quantities.
Frequently Asked Questions
What is the difference between a cable ladder and cable tray?
A cable ladder has an open rung structure for ventilation and high power-cable loads. A closed cable tray or trunking provides more enclosure for cables that need greater protection from dust or external contact.
How long does delivery take?
Delivery depends on dimensions, quantity, finish and production capacity. Powder-coated and GI cable ladders are generally faster than hot-dip galvanized items, which require a separate galvanizing process. The Sun confirms the delivery schedule with the quotation.
Can The Sun review drawings and prepare a quotation?
Yes. Send the drawings, specifications or quantity schedule. Our technical team can help identify fittings, estimate quantities and propose a cable ladder solution for the project.
Need a cable ladder quotation?
Send your specifications, quantities or CAD drawings. The Sun will advise on materials, accessories and a suitable solution for your installation.
