How are the commonly used elbows for cable trays made
Creating a 90-degree elbow in an electrical cable tray, often called a "fabricated" or "mitered" bend, involves cutting, bending, and fastening a straight section of tray. The most common method involves creating two 45-degree cuts to form a 90-degree angle. Most cable trays are made from metals like steel or aluminum because of their strength and resistance to corrosion. Aluminum: Preferred for its lighter weight and excellent resistance to corrosion. Metal elbows for cable trays are specialized components designed for electrical installations, allowing for efficient and safe routing of cable pathways at corners. A structural offset in the sidewall creates strong, mid-span splices. Common cable tray fittings include cable tray elbows, tees, crosses, bends, risers, reducers, bolts and nuts, locks, expansion screws, supporting brackets, suspension rods, cross arms, bases, connecting plates, covers, fixings, cable cleats, and system dividers. By providing a controlled pathway, cable tray bends help maintain the integrity and.
