Hastings designed the Super “U” Arm with a profile “U” shape for greater strength and durability. All arms include insulated conductor holders to ensure dielectric integrity.
Arms are rated for 34.5 kV phase-to-phase work applications. Arms with the standard conductor holder will accept conductors up to 1 1/16 in. O.D. or up to 800 MCM. Arms with the large capacity conductor holder can accommodate a conductor inside a line hose. The gate latch on the large capacity holder has an opening of 2 5/8 inches.
The Super “U” design is stronger than the traditional style round extension arms, according to the company. All Super “U” Arms and Super “U” Conductor Supports have a load limit of 200 lbs per wire holder. Interchangeable hanger loop kits are available for the different sizes of cross arms on your system.
Super "U" Arm Extensions can be found on page 307 of Hastings’ online catalog. For more information, call (269) 945-9541 or visit www.hfgp.com.
