Cable tray without cable fixing thread

Cable trays can be installed without threaded rods using mesh trays with snap-on connectors or alternative mounting systems, providing secure support and easy cable management.

Overview

Cable trays without cable fixing threads are designed to simplify installation while maintaining mechanical and electrical integrity. These systems eliminate the need for threaded rods or bolts, allowing cables to be laid and secured efficiently. They are particularly useful in industrial and commercial environments where flexibility, speed, and compliance with standards are important.

Types and Installation Methods1. Mesh Cable Trays with Snap-On Connectors Wire mesh trays, such as the MTC 54 series, allow for ceiling or wall installation without threading. The trays and fittings can be electrically and mechanically connected using integrated connector lugs, eliminating the need for additional fasteners.

They are available in widths from 100 to 400 mm and rail heights of 54 mm. Ceiling installations can use overhead hangers (HU 5050, HU 6040) or U-profiles and head plates for flexible mounting. 2.

Wall-

Mounted and Surface-Mounted Brackets Cable trays can also be mounted directly to walls or floors using brackets, clips, or mounting plates. This method avoids threaded rods and is suitable for areas with limited space or where overhead suspension is not feasible. Accessories like mounting clamps, tray hangers, and cable tie mounts help secure the trays and organize cables.

3. Compliance and Load Considerations These systems are designed to meet standards such as DIN EN 61537 for cable support systems. They can handle mechanical loads, environmental conditions, and maintain circuit integrity for fire-rated installations (E30, E60, E90) when used with appropriate cables.

Proper selection of tray type and accessories ensures safe and reliable cable support.

Advantages

Faster Installation: No need to thread rods or bolts, reducing labor time. Flexibility: Snap-on connectors and adjustable hangers allow easy modifications. Safety: Secure cable support reduces risk of cable slippage or damage.

Compliance: Meets industrial standards for mechanical and electrical performance.

Accessories

To enhance installation without threaded rods, consider: Cable Tray Hangers: Support horizontal runs from ceilings. Mounting Clamps: Secure trays to walls or surfaces. Connector Lugs: Snap trays together without additional hardware.

Cable Tie Mounts: Organize and restrain cables within the tray. Using these methods, cable trays can be installed efficiently, safely, and in compliance with industry standards, all without the need for threaded rods or traditional cable fixing threads.
