Wire Mesh Cable Trays Enhance Electrical Safety in Construction

Tangled cables present more than just an eyesore in data centers, factory floors, and commercial buildings—they pose genuine safety hazards. The Defem mesh cable tray system developed by Schneider Electric South Africa offers an efficient solution for managing these critical lifelines.

Defem represents a complete cable management system designed to provide secure pathways for power, data, and control cables. The system features three distinct surface treatments to accommodate various environmental requirements:

• Electro-galvanized: Ideal for dry indoor environments, providing basic corrosion protection.
• Hot-dip galvanized: Suitable for humid or mildly corrosive environments with enhanced protection.
• AISI316L acid-resistant stainless steel: Engineered for extreme conditions in chemical plants, offshore platforms, and similar harsh environments.

The standard mesh cable trays come in four heights (45, 55, 60, and 110 mm) and eight widths (ranging from 53 to 622 mm), with a standard length of 2.5 meters. For specialized applications, Defem offers C-shaped, G-shaped, and Z-shaped variants along with three mini mesh cable tray configurations.

Defem's design prioritizes safety, reliability, and installation efficiency:

• Enhanced load capacity: Constructed from high-strength steel wire with superior mechanical properties compared to conventional alternatives.
• Safety-focused design: Rounded edges prevent installer injuries and cable damage.
• Modular installation: Comprehensive support accessories accommodate wall mounting, floor placement, ceiling suspension, and U-channel supports.
• Compliance certified: Meets IEC 61537, UNE EN 50102, and UNE EN ISO 9227 standards, with DIN 4102-12 fire rating (E90) certification.

The system serves diverse environments from commercial spaces to demanding industrial settings:

• Standard indoor use: Offices, retail spaces, and IT facilities
• Industrial applications: Wind farms, food processing plants
• Extreme environments: Oil/gas facilities, chemical plants, maritime installations

The Defem system delivers measurable benefits for infrastructure projects:

• High load capacity with 2-meter support spacing
• Simplified installation requiring only three connector types
• On-site fabrication of elbows, reducers, and tees
• Exclusive DNV certification for marine applications

The three surface treatments address progressively demanding environments, from basic indoor protection to extreme corrosion resistance in chemical processing and offshore applications.

The open mesh structure promotes ventilation while allowing visual cable inspection. The system's modular components support flexible routing configurations without requiring prefabricated parts.

Lightweight construction and tool-free assembly reduce labor requirements. Field-adjustable components eliminate the need for custom manufacturing, minimizing project timelines.

From commercial developments to critical infrastructure, the system accommodates power distribution, data networks, and control systems across multiple sectors including transportation hubs, manufacturing plants, and specialized industrial facilities.
