    Aluminum construction, exceptional engineering and ease of installation
    reduce substation costs as much as 25%

    Turner’s SilverTip® 1TSB switch is an aluminum side break switch well suited for horizontal and vertical applications on the transmission system as well as in the substation environment. Unlike many so-called transmission-switching products that are merely substation switches modified for use on the transmission system, the 1TSB is a true transmission switch.

    It is designed and built for the harsh environmental conditions, galloping conductors and constant pole movement inherent in severe aerial applications.

    The 1TSB switch mounting flexibility makes it ideal for horizontal or vertical configurations on poles, on platforms, or on substation structures. Designed as a stock switch, the 1TSB is suitable for almost any application.

    SilverTip 1TSB switches on your system will:

    reduce construction costs – easily upgraded in the field . Don’t replace the blade or jaws, just reblade or rejaw! And, there’s no “toggle” adjustment during install.

    reduce maintenance costs – spring-loaded reverse-loop jaw design increases contact pressure, regardless of faults or surges.
    Exclusive blade lock keeps blade closed under galloping conductors.
    Patented rotating-blade design rolls the blade in the jaws to lock and unlock.

    and lower your inventory costs – – live parts are interchangeable through the full voltage and current range (15 – 61kV, 600-2000 amps).

    Like the Silvertip shark’s double row of teeth, Turner’s SilverTip® 1TSB switch jaw contacts increase their holding power under resistance.

    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.

    In fault conditions, the increased current flow increases the pressure, retaining the blade in the jaws.

    Blade Design

    The aluminum tubular blade design provides the proper combination of current-carrying capacity and rigidity. Silver-plated copper blade tips are easily field-replaceable, as are stationery and moving arcing horns.

    Rotating Blade Technology

    The gentle ways of the Silvertip shark earned it the name of “gentleman shark”. SilverTip® 1TSB switches gently close into position, with the blade tip engaging the jaws at a 30 degree angle, then rotating to engage the jaw contacts. They are not “slammed” under force into the contacts.

    Both the blade and jaw contacts are wiped clean during the closing action to ensure a low resistance current transfer. A heavy-duty blade-locking device keeps the blade closed despite temporary faults, surge currents, twisting structures or galloping conductors.

    The lock is released during the switch opening sequence, as the blade rotates 30 degrees in the jaw. This action, exclusive to Turner’s SilverTip 1TSB switches, breaks up any ice or contamination, and releases the contact friction, allowing the blade to easily be removed from the contacts.

    Hinge Mechanism

    The hinge end of the switch is enclosed to permanently protect it from the elements and offers a continuous current carrying path. 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.

    As the switch rotates during the opening and closing cycle, the terminal pad is held in place by the conductor allowing the switch to move without restriction. Inside the hinge housing, current transfer from the stationary block to the moveable blade is achieved through a series of spring-loaded silver contact segments. This hinge configuration ensures maximum service life with minimum maintenance.

    Main Bearing Assembly and Stationary Insulator Mounting

    The main pivot bearing assembly consists of two tapered roller bearings, which are adjusted and factory lubricated. They require no further attention for the life of the switch. These bearings are protected with a permanent neoprene seal with a Welch type expansion plug.

    Leveling screws are provided on the movable and stationary insulator mounting flange to facilitate easy alignment of the insulator stacks. Adjusting the movable mount leveling screws raises or lowers the end of the switch blade allowing simple, correct blade to jaw contact interface.

    Make Your Side Break a Load-Break Switch

    For more than 35 years, Turner Electric’s TECO-Rupter® Vacuum Interrupters have been the technology of choice for loop and load-break applications because of their current-interrupting ability, superior reliability and ease of application.

    The TECO-Rupter offers industry leading performance levels including superior TRV ratings compared to other load-break technologies such as SF6, longer service life and greater interrupting capacity. No other load-break device provides 5,000 full load operations at either 2,000 or 3,000 Ampere ratings and a TRV rating up to 57kV.
