The XA_50063_J is a 15_foot expansion section designed for the Hevi_Bar_II 700_amp conductor bar system, built to accommodate thermal expansion and contraction in high-amperage applications. This model includes a red polycarbonate cover rated for medium heat environments up to 250_°F, making it ideal for indoor or partially sheltered applications where elevated temperatures are common. The expansion section is pre-assembled with a splice, simplifying installation and ensuring strong electrical continuity. A Dura_Coat finish enhances the system's resistance to corrosion, supporting reliable performance in demanding industrial operations such as steel mills, foundries, or heavy-duty cranes. Key Features 700_Amp Current Rating – Designed for heavy-duty industrial power transmission. 15 ft Expansion Length – Supports thermal compensation in shorter high-load systems or where space is limited. Red Medium_Heat Polycarbonate Cover – Durable, impact-resistant insulation rated up to 250_°F; color-coded for ground conductor. Pre-Spliced for Easy Installation – Ships with splice installed, reducing field labor and installation time. Dura_Coat Finish – Corrosion-resistant coating enhances long-term durability in aggressive environments. Thermal Management Solution – Recommended for runs exceeding 390_ft to prevent conductor misalignment and stress. Hevi_Bar_II System Compatible – Works with standard hangers, powerfeeds, and other 700_A components.
