25 KV UNDERARM SIDE-BREAK SWITCH, MANUAL ANDAUTOMATED

Prepared by: EOB1

Purpose and ScopeThis document specifies the requirements and preferred installation of manual and automated 25 kV underarm side-breakswitches (U.S. Switch).

General Information, Both Manual and Automated Switches

1. The U.S. Switch is required to be designed, manufactured, and tested to meet all applicable ANSI (AmericanNational Standards Institute) standards, IEEE (Institute of Electrical and Electronic Engineers) standards, and allrequirements shown and described in this document. In addition, the U.S. Switch is required to be tested to meetthe CDF (California Department of Forestry) requirements and qualified as exempt electrical equipment.

2. Switch Code 341575 (manual) or switch Code 341497 (automated) are for use in all switch applications anddistricts, except for 21 kV in AA insulation districts. For 21 kV in AA insulation districts, use switch Code341576 (manual) or switch Code 341488 (automated). The Cooper/Kearney and the S&C U.S. Switch bothuse epoxy insulators, and Inertia uses station post silicone rubber insulators.

3. The switch codes shown in this document are for the U.S. Switch. These switches are shipped as tangent3-wire, and are adaptable to all line configurations; e.g., tangent 4-wire, angle, tangent riser, dead-end riser,alley arm, etc.

4. Caution: The U.S. Switch is designed and manufactured to be installed in the underarm position only. Do notinstall this switch in the upright position. The bell crank operation will be reversed causing the switch tooperate opposite of the normal open/close positions.

5. Non-ceramic dead-end insulators and extension links are not included by the manufacturer of the switch andmust be ordered separately. Extension links are required for all installations where dead-ending occurs on theswitch arm dead-end bracket. Important: Three extension links are required per phase for the automatedswitches; i.e., two extension links on the sensor insulator side and one extension link on the opposite side.

6. The U.S. Switch is furnished with terminal paddles for use with fired wedge connectors. Select theappropriate fired wedge connector from Document 066194 by using 397.5 AAC (terminal paddle size) forone groove size, and the line conductor size for the other groove size. The terminal paddle has a normalampacity rating of 900 amperes. Do not unbolt and reuse paddle assemblies. New assemblies must beused (see Table 9 on Page 9, Code 340361).

7. In order to maintain the 36-inch climbing space for below pole-top installations, the U.S. Switch ismanufactured with approximately 24 inches of phase spacing. Limit span lengths to approximately 400 feetwith the 24-inch phase spacing. When the switch is mounted at pole top, additional phase spacing can beachieved by moving the center dead-end bracket next to the pole mounting bracket. Moving this centerdead-end bracket will allow for span lengths greater than 400 feet and will provide increased raptor protection.

8. Switches are permitted in the working space, but switches, or any part of the switch, must not be installed inthe climbing space.

9. Install the switch handle (bottom when opened) or MSO controller (bottom of cabinet) at a minimum of 15 feetabove the ground line.

10. Attach the operating numbers to the pole in a vertical configuration below the switch handle or MSO controller. Ifthe numbers cannot be readily seen from the road, install an additional set of numbers at the 9-foot level on thetraffic side of the pole.

Installation Instructions

Manual Switch and Switch Portion of Automated Switch

11. The U.S. Switch is unitized and fully adjusted at the factory. The following are the manufacturer’s installationinstructions:A. The U.S. Switch manufacturers apply “Conducto-Lube” switch contact lubrication at the factory. During

installation, do not apply additional contact lubrication or any other product to the contacts. After a few years,a switch may become stiff and difficult to operate. If that occurs, sparingly apply “Conducto-Lube” (Code 495346) to the overhead switch contacts.

B. All Cooper U.S. Switches are furnished with three galvanized steel channels for mounting larger diameterpost-type insulators to the steel crossarm. Note: Tighten the bottom nut and lock washer to the bottom of thesteel crossarm. The phase unit has a large hole for inserting a socket.

C. Mount unitized switch to pole with 3/4-inch bolts at the desired location, using TECO shear plates as shown in“Mounting Detail” on Page 10.

D. Attach eye bolt guides to pole as required and thread 1-inch fiberglass through guides and attach to clampon bell crank.

E. Use only the switch handle that comes with that switch. The manufacturers use different throws, so mixinghandles will not work.

F. Attach control rod to control handle with the control handle and adjusting clevis in position and mount handleto pole with 5/8-inch bolts. Adjust the control rod to have a slight compression load against the switch bellcrank when the switch is in the fully closed position; i.e., there must be a slight bow in the fiberglass controlrod when the switch is in the fully closed position. Use approximately 1-1/4 inches of compression for 30 feetof rod.

G. Remove factory-installed contact blade shipping ties.

H. Check interrupters individually for proper operation. Operate each interrupter by hand. A “slamming action”should occur when testing each one by moving the rod/rocker through its complete arc. A defective loadinterrupter will have a consistent spring tension without the “slamming action.” Simply testing the switch after ithas been installed will not detect this problem.

After testing the interrupters, make sure that each interrupter is cocked (in the correct position for the nextswitch operation). If an interrupter is not properly cocked and latched, a load-break switch operation will mostlikely result in a flashover and a switch failure.

I. Operate the switch several times and check for any difficulties. A compression load should be felt on thecontrol at the end of the closing stroke. Adjustment of load can be made by adjusting clevis as needed.

J. For Cooper Switch

(1) Check to be sure that all phases are fully closed. Ensure that the reliabreak trip arm is passed through thecatch arm in the latched position; if not, adjustment should be made at adjusting clevis. If for some reasononly one or two phases are not fully closed, adjustment should be made at the interphase clamp of that unit.

K. For S&C Switch(1) Check to be sure that all phases are fully closed by visually inspecting that the blades are parallel to the

pole-unit bases. If for some reason only one or two phases are not fully closed, adjustment should bemade at the interphase clamp of that unit. The switch is properly closed when all blades are parallel to thepole-unit base, the operating linkage is in the over-toggle position, and the yellow flag on the top of theinterrupter is not visible.

(2) When reconfiguring a factory-assembled switch to an alley arm switch, follow S&C installation Drawing Number ED-8038 which is shipped with all S&C switches.

L. For Inertia Switch

(1) Verify the switch operation by closing the switch with the minimum force required to fully close at theswitch. The load interrupter flag (LIF) yellow reflector will rotate from the horizontal to the vertical positionindicating a closed and latched switch. If for some reason all phases do not close, loosen the phase crankclamp of the phase that is not closed, manually close the switchblade, and tighten the clamp.

Note: Do not lift switch by main contact during installation.

Installation Instructions (continued)

12. Operation: The U.S. Switch should be opened or closed with one swift operation. Caution: Do not tease theswitch while opening or closing. After closing the switch, look up to make sure all phases are fully closed. Theswitch blade must be parallel with the phase unit channel. The following are the instructions for making sure thateach of the phase unit interrupters are latched:

A. On the Cooper switch, the worker must look up at the rods on the interrupter to make sure that they arelatched before opening the switch.

B. On the S&C switch, there is a yellow flag on the top of the interrupter to warn the worker if the interrupter isopen or closed. The yellow flag is present when the switch is open. In other words, the worker must look up atthe interrupter to verify that a yellow flag is not present and that the blade assembly is parallel to the pole-unitbase when the switch is closed.

C. On the Inertia switch, there is a reflective yellow flag on the rotating switchblade that is visible when the switchis open or the interrupter is not latched. The worker must look up at the interrupter when closing the switch toverify that the yellow flag is not present. Properly latched interrupter flags can be seen when viewing theswitch on the crossarm pole face from a distance of at least 30 feet.

Automated Switch Only – Inertia Switch and Motor Switch Operator (MSO)

13. Remove the control rods, MSO, and rod splices from the crate. Remove the top boards of the shipping crate andattach hoisting slings to the 5/8” holes in the two outermost phase base channels.

Note: The automated switch is completely unitized on a common steel crossarm at the factory and requires nofield adjustment. The switch is always mounted in the underarm position. Maintain all required clearanceswhen installing this equipment.

14. Install the switch portion of the automated switch as indicated in the “Manual Switch” section. Exception: SeeNote 5 on Page 1 for automated extension link requirement.

15. Drill two MSO mounting holes at 33-1/2” center-to-center distance in line with the switch control rod. Install theMSO, using two 5/8” pole bolts Verify the MSO operating mechanism is in line with the control rod (see Figure 15on Page 24).

16. Install the eyenuts and bolts through the pole and make alignment adjustments so that the control rod makes asmooth transition from the switch bell crank to the MSO output shaft. Tighten the eyenuts and space bolt nuts onthe pole and cut off any excess.

17. Verify that the switch and the MSO are in the closed position. Attach the MSO adjusting screw and control rodclamp to the MSO output shaft and cut the fiberglass control rod as shown in Figure 15 on Page 24.

18. Connect the control rod to the control rod clamp. Adjust the control rod to have a slight compression load (useapproximately 1-1/4 inches of compression for 30 feet of rod) against the switch bell crank when in the fullyclosed (up) position by using the MSO adjusting screw, and/or adjusting the adjusting screw control rod clampposition. Remove the factory-installed shipping ties from the rotating blade/female clips.

19. Check all control rod clamps and mounting hardware for proper torque. Operate the switch slowly several times toverify that the moving switch contact blades fully seat in the female contact clips. The automated switch movingcontact blade is in line with the insulators when the switch is fully closed. Adjust the MSO control rod by adjustingthe nut screw as required, to establish full seating of the contacts. The control rod should be adjusted so that theswitch fully closes with the interrupters latched, when the switch is operated slowly. Note: During manualswitching operations, the automated switch should be operated with rapid and continuous motion from start tofinish. Return the handle and operating motor interlock pin to their storage positions inside the MSO whenadjustments are completed.

20. A control power source of 120 Vac is required as follows.

A. Common Neutral Systems: The supply voltage transformer can be installed on the SCADA switch pole or anadjacent pole. The control, switch arm, and transformer neutral shall all be connected to the pole ground. Thepole ground shall be connected to the common neutral conductor.

B. Non-Common Neutral Systems: The supply voltage transformer can be installed on the SCADA switch pole oran adjacent pole. The supply voltage transformer must be a dedicated transformer; i.e., no other loads,grounds, neutrals, or services are to be connected to this transformer.

Automated Switch Only – Inertia Switch and Motor Switch Operator (MSO) (continued)

21. Pull the hinged door of the F1 and F2 control fuses in the MSO. Install and connect the 120 Vac leads onto thelanding lugs in the MSO (see Figure 17 on Page 26). Connect the MSO battery leads together and replace thecontrol fuses.

22. Check the MSO on local control with the clutch engaged (coupled position) and the operating pin installed. Verifythe lockout light is not lit and electrically operate the MSO to open the switch. Note that the MSO prevents switchdamage by stopping the motor prior to full open position. Electrically close the switch and verify that the contactsare fully seated. Operate the switch to close a minimum of ten times to verify proper control rod adjustment.

23. Leave the switch in the proper operating position (open or closed) with the MSO door closed and locked. Makesure all control features are cut in or cut out as dictated by switching instructions. Release the switch and MSOfor local electrical operation to the appropriate switching center. Note: Make sure any abnormal control featuresare properly tagged before releasing the unit to the switching center.
