High-quality long-span cable trays
Long-span cable trays are engineered for heavy-duty, industrial cable support with high load capacity, corrosion resistance, and durability for indoor and outdoor applications.
Overview
Long-span cable trays are designed to support heavier cables over larger spans than standard trays, making them ideal for industrial, mining, petrochemical, and infrastructure projects . They provide a robust structural solution for overhead, underground, and outdoor cable installations, ensuring safety, reliability, and ease of maintenance.
Types and Materials
- Ladder Type: Offers maximum ventilation and easy cable installation; widely used in oil, gas, and renewable energy sectors .
- Channel Type: Suitable for medium loads and compact installations.
- Perforated Type: Provides good airflow and heat dissipation, reducing the risk of short circuits . Materials commonly used include:
- Stainless Steel (304/316): Excellent corrosion resistance and durability.
- Aluminum Alloy: Lightweight and resistant to corrosion.
- FRP (Fiberglass Reinforced Plastic): High strength, heat resistance, and suitable for harsh environments . Finishes: Pre-galvanized, hot-dipped galvanized, and powder-coated surfaces enhance corrosion resistance and longevity.
Key Features
- High Load Capacity: Engineered to carry heavy industrial cables over long spans without sagging .
- Durability: Resistant to heat, humidity, and harsh weather conditions; maintains shape and performance over time .
- Ease of Installation: Compatible with accessories like corbels, hangers, and fixations for flexible layouts .
- Fire-Rated Options: Some systems, like BAKS E90, ensure uninterrupted cable function for up to 90 minutes in fire conditions .
- Versatility: Suitable for indoor, outdoor, and underground applications, including subways and civil defense projects .
