The XA_50817_J is a 20-foot expansion section for the Hevi_Bar_II 1000_amp conductor bar system, designed to manage thermal movement in long, high-amperage conductor runs. This section features a red medium-heat polycarbonate cover rated for temperatures up to 250_°F, offering enhanced durability and impact resistance in elevated heat environments. It is ideal for indoor or partially enclosed industrial applications where ambient temperatures are higher than standard. The unit is pre-spliced for simplified installation and includes a Dura_Coat finish for superior corrosion resistance, ensuring a long service life in demanding environments such as steel processing facilities, large manufacturing plants, and high-capacity crane systems. Key Features 1000_Amp Current Rating – Supports very high current loads for heavy-duty mobile electrification. 20 ft Expansion Length – Accommodates conductor growth due to thermal expansion in long-run systems. Red Medium_Heat Polycarbonate Cover – Rated to 250_°F; durable, non-metallic, and color-coded for ground conductors. Pre-Spliced Assembly – Includes factory-installed splice for faster, easier, and more secure installation. Dura_Coat Finish – Ceramic-epoxy coating protects the conductor bar from corrosion and harsh industrial exposure. Ideal for High-Temperature Areas – Perfect for systems exposed to moderate heat but not direct sunlight. Compatible with Hevi_Bar_II Systems – Fully integrates with all standard 1000_A bars, supports, and accessories.
