Overview

The ABB XJG Conduit Expansion Coupling, SKU XJG78-TB, is engineered for critical electrical installations requiring reliable expansion and contraction management within conduit systems. This 2-1/2 inch coupling features a robust malleable iron body, zinc-plated for enhanced corrosion resistance in industrial environments. Designed to accommodate significant axial movement, it offers up to 8 inches of expansion and contraction, ensuring the integrity of your conduit runs under thermal stress or structural shifts. A key feature of the XJG78-TB is its integrated internal bonding jumper. Constructed from tinned copper braid, this jumper provides a continuous, low-impedance path for electrical continuity, essential for maintaining safety and grounding integrity across the expansion joint. This is crucial for applications where maintaining a reliable ground connection is paramount, such as in hazardous locations or areas with stringent electrical codes. The packing material utilized in this coupling is a combination of PTFE and synthetic fiber, selected for its durability and resistance to environmental factors. This ensures a secure seal while allowing for smooth, unimpeded movement. The XJG series is specifically designed for applications where conduit systems must accommodate thermal expansion and contraction, preventing stress on fittings, cables, and the conduit itself. This coupling is ideal for use in power distribution, industrial facilities, and infrastructure projects where long-term reliability and electrical safety are non-negotiable. The combination of durable materials, precise engineering, and integrated safety features makes the ABB XJG Conduit Expansion Coupling a dependable choice for demanding electrical infrastructure projects.
