The XA_50741G_J is a heavy-duty expansion section specifically designed for the Hevi-Bar II 500_amp conductor bar system. It provides thermal expansion compensation in applications with long conductor runs, helping maintain bar alignment and electrical integrity. This model features a green medium-heat polycarbonate cover rated up to 250_°F, signifying its use as a ground conductor and ensuring resilience in indoor or UV-exposed environments. With a closed length of 30 feet, this section is ideal for overhead cranes, automated material handling systems, and similar industrial applications where thermal movement must be managed effectively. Key Features 500 Amp Capacity – Matches Hevi-Bar II system standard for high-current industrial power transfer. Green Polycarbonate Cover – Medium-heat (250_°F) insulated cover, color-coded for ground conductor applications. 30-Foot Expansion Length – Compensates for thermal expansion/contraction in conductor runs up to 350_ft. Durable and Weather-Resistant – Suitable for both indoor and outdoor installations, including high-vibration areas. Low-Maintenance Design – Built with high-performance materials for long-term reliability with minimal upkeep. Part of Hevi-Bar II System – Fully compatible with related hangers, connectors, and powerfeed components.
