Side-Break Switches for Line Capacity Upgrade

The Rockwill offers the most versatility, compared to other side break switches. The unique frame design, with conductor deadends right on the frame, easily orients to the line angle. Additional positions can be added quickly and with minimal effort. The RDS-1AS2 can also be offered in two, three, and four way mounting configurations for inline or 90 degree takeoffs. By adding a specially designed pole bracket, you have maximum switching flexibility.

Features of the Rockwill RDS Features

• Speed Independent operation—can be closed either fast or slow
• Reverse-loop, silver plated copper jaw contacts—employ the natural repulsion of magnetic fields moving in opposite directions to exert holding forces against the blade edges.
• Components—The 6063-T6 aluminum tubular blade design provides the proper combination of current carrying capacity and rigidity. Silver-plated copper profiles are easily fieldreplaceable, as are the stationary and moving arcing horns.
• Blade Action—Both the blade and jaw contacts are wiped clean during the closing action to ensure a low resistance current transfer. A heavy-duty static blade locking device keeps the blade closed despite temporary faults or surge currents and is designed to pull the blade further into the jaw.
• Anti-Rollover Device—The BearTrap Switch from Turner employs a patented ramp and pin to securely position the blade in the jaw.
• Blade Position Indicator—High visibility stickers provide positive indication of the switch being open or closed. They also have high UV protection and come standard on every switch.
• Current Transfer—There are only two current transfer points in the hinge. The terminal pad is threaded to a stationary contact block creating a spring loaded, silver to silver connection, and the housing transfer current to the blade via a canted coil spring.
• Upgrade-Ability—Ratings can be increased from 600 amps to 1200 amps by adding bolt-on contact fingers to the jaw.
• Main Bearing Assembly And Stationary Insulator Mounting—The main pivot bearing assembly consists of two tapered roller bearings, which are adjusted and factory lubricated.
• Leveling—Leveling screws are provided on the movable and stationary insulator mounting flange for alignment of the insulator stacks. Three bolts are also on the jaw end for small final
  adjustments.
• Mounting—All frames are designed and constructed for termination of the transmission line a 10,000 pounds working load. Line angles at full tension are limited to +/-5 Degrees of 90 or 180 Degree dead end. If there is an application outside of these parameters, please contact the factory.
