Long Span Ladder Type, Long Span Solid Bottom Type, Long Span Perforated Tray Type, matched with cover plates and separator plates for strong & weak current separation.

Long Span Cable Tray Introduction（English Version for Foreign Trade）

1. Definition

Different from standard cable trays, long span cable tray features single section standard spans of 2m, 3m, 4m, 6m, with customized maximum span up to 8 meters without intermediate support columns. With high-rigidity structure, it reduces the quantity of support columns and brackets, specially designed for overhead high-altitude laying in steel structure workshops, pipe galleries, substations, wind power, energy storage stations and sites with large column spacing.
Executive Standard: JB/T 10216, GB/T 23639.

2. Structural Features

1. Heightened & thickened side plates, integrated bending + embossed reinforcing ribs design, excellent anti-bending and anti-deflection performance, much higher load capacity than ordinary trays, no sagging or twisting during long-term overhead installation.
2. High structural integrity with reinforced connecting plates at joints for stable connection.
3. Three mainstream types available: Long Span Ladder Type, Long Span Solid Bottom Type, Long Span Perforated Tray Type, matched with cover plates and separator plates for strong & weak current separation.

3. Core Advantages

1. Lower auxiliary material cost
Long span design greatly cuts the usage of columns, brackets and fasteners, saving 20%~35% overall cost on accessories and construction labor.
2. High installation efficiency for high-altitude work
Whole-section hoisting with fewer splicing joints, simplified construction procedures, shorter construction period and lower safety risks for aerial workers.
3. Super heavy load capacity
Perfect for laying multiple large cross-section high-voltage power cables, stable bearing performance without deformation.
4. Diverse anti-corrosion options
Electro-galvanized, powder coated, hot-dip galvanized, aluminum alloy, 304/316 stainless steel optional, applicable for outdoor, coastal and corrosive environments.
