The XA_39741_J is a 30-foot expansion section for the Hevi_Bar_II 500_A conductor bar system, designed to compensate for thermal expansion and contraction in long conductor runs. This model features a standard heat-rated orange PVC cover, ideal for indoor or covered environments where high ambient heat or UV exposure is not a primary concern. The Dura_Coat protective finish enhances durability in industrial settings, while the pre-installed splice allows for quick and secure integration. Used primarily for mobile power applications, such as cranes and material handling systems, this expansion section maintains electrical continuity and structural alignment under thermal changes. Key Features 500_Amp Rating – Matches standard Hevi_Bar_II system requirements for heavy industrial loads. Orange Standard Heat PVC Cover – Identifies ground conductor; suitable for general-purpose indoor or protected-area installations. 30 ft Expansion Length – Compensates for bar movement due to thermal expansion over long conductor spans. Pre-Spliced for Installation – Ships with splice assembled for simplified field installation. Dura_Coat Finish – Provides corrosion resistance and extended service life in rugged environments. Fully Compatible – Integrates seamlessly into Hevi_Bar_II systems with matching supports, hangers, and accessories.
