1 S&C Omni-Rupter Switches Outdoor istribution (14.4 kv and 5 kv) Specifications Conditions of Sale STNR: Seller s standard conditions of sale as set forth in Price Sheet apply. SPECIL TO THIS PROUCT: INCLUSIONS: S&C Omni-Rupter Switches are threepole, group-operated interrupter switches offered in the side-break integer style. These switches are available with either steel or insulated bases in the Mounting Configurations and Standard Mounting rrangements shown in the tables on pages 4 through 7. Each switch is provided with an operating mechanism designed for the applicable Standard Mounting rrangement. Each shipment of one of these switches will include: three-pole switch, complete with interphase drive, factory-assembled on a single base ead-ending brackets for each switch pole (except vertical mounting configurations); requires an optional pole-band Silver-plated contacts and terminal pads single-point lifting bracket in the upright, inverted, and vertical mounting configurations, permanently installed for convenient rigging and hoisting during installation The appropriate detailed erection drawing (E) Complete installation instructions In addition, the following items will be provided depending upon the style of operating mechanism. For hookstick-operated switches (E-700R4, E-706R4, E-707R4, E-709R4, E-710R4, E-716R4, E-717R4, and E-719R4): crossarm mounted pull-pull-type manual operating handle, a retention mechanism to hold the switch in the open position, and provisions for the switch to be locked/tagged out in the open position (lthough these items will be assembled to the switch and adjusted for proper operation at the factory, some minor disassembly is required for shipping purposes. However, no adjustments should be necessary following reassembly in the field.) vailability of a hookstick-operated lockout/tagout device for hookstick-operated Omni-Rupter switches in the upright, upright with extra mounting-pole clearance, tiered-outboard, and inverted configurations (Select the catalog number with the -H suffix to add this option.) Rural Utilities Service has accepted a wide variety of Omni-Rupter Switch styles and configurations. For vertical-operating-shaft switches (all other Es): Four sections of 6-foot-10-inch (08.8 cm) vertical operating pipe as specified on the erection drawing for the applicable Standard Mounting rrangement The appropriate set of operating-mechanism components for the vertical operating pipe; e.g., handle, rod guides or guide bearings, and couplings S&C Omni-Rupter Switches have a two-time duty cycle fault-closing capability of 4,000 amperes, peak, and a 10-time duty cycle fault-closing capability of 1,000 amperes, peak. ccordingly, these switches may be closed the specified number of times at the indicated current while remaining operable and able to carry and interrupt rated continuous current. Omni-Rupter Switches in the upright and triangular mounting configurations are capable of being opened and closed under ¾-inch (19.05-mm) ice formation. Switches in the upright and triangular mounting configurations provide this capability inherently. Switches in the tiered-outboard and vertical mounting configurations require the addition of ice shields to ensure a ¾-inch (19.05-mm) ice breaking capability on opening and a ⅜-inch (9.55-mm) ice breaking capability on closing. Switches in the inverted mounting configuration require the addition of ice shields to ensure a ¾-inch (19.05 mm) ice breaking capability on opening and closing. For details, refer to Table 5 on page 8. EXCLUSIONS: Switches do not include extension-link assemblies, brackets for mounting surge arresters, pole band and J-bolts, or ice shields listed in Table 5 on page 8, nor do they include connectors. Various connector arrangements are available as listed in Table on page 3. POWER OPERTION: Power operation or, if desired, remote supervisory control may be provided for S&C Omni- Rupter Switches by the addition of the S&C 6801M utomatic Switch Operator. The 6801M Switch Operator is available in two versions: reciprocating, for reciprocatingtype operating mechanisms; and rotating, for rotating-type operating mechanisms. S&C Omni-Rupter Switches furnished with 6801M utomatic Switch Operators have a two-time duty cycle fault-closing capability of 3,500 amperes peak for standard switches only. Switches in the upright and triangular mounting configurations using the 6801M utomatic Switch Operator are capable of being opened under a ¾-inch (19.05-mm) ice formation and being closed under a ⅜-inch (9.55-mm) ice formation with the addition of ice shields. Switches in the vertical and tieredoutboard mounting configurations using 6801M utomatic Switch Operators are capable of being opened under ¾-inch (19.05-mm) ice formation and being closed under ½-inch (1.7-mm) ice formation. For additional details concerning the S&C 6801M utomatic Switch Operator, refer to Specification Bulletin July 18, 016 S&C Electric Company , all rights reserved Specification Bulletin
