The XA_50743_J is a 20-foot expansion section for the Hevi_Bar_II 1000_A conductor bar system, designed to compensate for thermal expansion and contraction in long, high-capacity conductor runs. Featuring an orange PVC cover rated for standard heat environments (up to 160_°F), this expansion section is suitable for indoor or protected applications. It comes pre-assembled with a splice, allowing for easy and efficient integration into the conductor bar system. The included Dura_Coat finish provides excellent corrosion resistance, ensuring durability and long-term reliability in industrial environments such as manufacturing plants and indoor crane systems. Key Features 1000_Amp Current Rating – Designed for very high-power applications in industrial settings. 20 ft Expansion Length – Manages thermal movement in long conductor runs, preserving electrical continuity. Orange Standard Heat PVC Cover – Color-coded for phase conductor; suitable for general indoor use (up to 160_°F). Pre-Spliced Assembly – Factory-installed splice simplifies setup and ensures a secure electrical connection. Dura_Coat Finish – Protective ceramic-epoxy coating resists corrosion and harsh environmental exposure. Thermal Compensation – Recommended for installations exceeding 390_ft in length to mitigate expansion-related stress. System Compatible – Fully compatible with Hevi_Bar_II 1000_A accessories, hangers, and powerfeeds.
