The XA_50741_J is a 30-foot expansion section built for the Hevi_Bar_II 500_A conductor bar system, engineered to handle thermal expansion in long power runs. This unit features a red medium heat-rated polycarbonate cover, offering enhanced durability and thermal stability for elevated temperature environments. Designed for use as a ground conductor, this section is supplied pre-spliced for simplified installation and includes a Dura_Coat finish for corrosion resistance in industrial settings. Its robust construction ensures continued electrical continuity and structural integrity in applications like overhead cranes, monorails, and automated transfer systems. Key Features 500_Amp Capacity – Compatible with Hevi_Bar_II systems for high-current industrial applications. Red Medium Heat Polycarbonate Cover – Heat-rated for environments up to 250_°F; durable and impact-resistant. 30 ft Expansion Length – Designed to accommodate thermal movement in long conductor bar runs. Pre-Assembled Splice – Enables quick, secure field integration without additional assembly. Dura_Coat Finish – Protects the aluminum bar from corrosion and wear in demanding environments. Color-Coded for Ground – Red cover indicates ground conductor; supports safe and compliant system configuration. Indoor/Outdoor Use – Suitable for both indoor factory settings and outdoor installations requiring moderate heat resistance.
