c. Switch Pole Construction: Switches shall be suitable for the specified ratings.

(1) Contacts: Main blade switch contacts shall be self-aligning, self-wiping, high pressure contacts.

Fixed contacts shall be of the reverse current loop shape that eliminates contact burning under fault conditions. The current-carrying path shall not be through any spring. If the current path is through a moving pin, means shall be provided to maintain continuous positive contact pressure on the pin. The shape and material used for contacts shall be such that there will be no galling of contact metals when switch is subjected to 1,000 open plus 1,000 close operations.

(2) Main Switch and Grounding Switch Blades: The blades shall be of hard-drawn copper or aluminum alloy for carrying the specified continuous and short-time currents. If the blades are attached to castings, the blades and castings shall be connected by welding or by a bolted clamp.

A press fit between blade and casting is not acceptable. Main blades of the vertical break switches shall be counterbalanced to prevent them from falling closed from any position. If spiral springs are used on the hinge end of a switch for counterbalancing, the housing shall be designed so that ice cannot build up on the spring(s) to impair switch operation. Pressed-fit joints shall not be subjected to spring pressure during any part of a switch operation.

The movement of all grounding blades shall be in a plane parallel to the main blades. When in the open position, the tip of the blades shall not extend beyond the base of the switch in a direction parallel to the main blades.

(3) Hinge-End and Clip-End Assemblies: Pole unit castings shall be of bronze or aluminum alloy.

Bearings in the hinge-end operating levers shall be of the ball, roller, Oiltite®-sleeve, plastic, or ball-and-socket type. Bearings shall be firmly fixed in place and shall not require replacement or maintenance before performing at least 1,000 operations, in ambient conditions specified in Table A above. The rotating arm and the hinge assembly of the disconnect switch shall be insulated from the current carrying blade such that no current passes through either at the rated capacity of the switch.

(4) Stops: Stops shall be provided in the clips-ends of vertical-break switches, and the switch adjustments shall provide for blades to rest against the stops in the closed positions.

Each switch shall be equipped with adjustable stops for the open and closed positions. The closing stops shall position each blade such that maximum contact pressure will be achieved between the moving and the fixed contacts. When a horizontally mounted switch is in the fully closed position, the hinge-end and clip-end contacts on each side of the main blades shall be horizontal within plus or minus 5 degrees for vertical-break switches.

With the closing stops adjusted for proper closed position of each blade, the three blades of each switch, when fully open, shall conform in position within 5 degrees of the manufacturer’s specified open position.

Stops shall be provided at bell cranks, independent of/in addition to stops provided at the motor or worm gear operating mechanism.

The stop adjustment method shall include means to prevent unintentional change in the adjustment, such as by jam nuts and/or piercing set screws.

(5) Rotating Insulator Bearings: Bearings for the rotating insulator stacks shall be of the tapered-roller or double-ball type. If of the latter type, the bearings shall be of the combination radial and thrust type. Bearings shall be provided with a readily adjustable take-up adjustment.

(6) Bases: The bases of switches shall be of metal members of sufficient stiffness to prevent excessive deflection when mounted and operated on supporting structures. Lattice-girder-type bases will not be permitted. Steel material required for the bases shall be galvanized.

(7) Bearings: Ball or roller bearings shall be the sealed, permanently lubricated type or of the type that does not require lubrication, with stainless steel balls or rollers and races.

d. Operating Mechanisms: Operating mechanisms shall effect a smooth, thoroughly controlled movement throughout the entire opening and closing cycles and all rods, shafts, pipe linkages, connectors, operating levers, supports, and fittings shall show no noticeable deflection. Cable connections in lieu of rigid interphase rods are not acceptable. Means shall be provided on each switch for taking up loose motion in each part of the mechanism and for adjusting the travel of each blade independently. U-bolts and U-bolt type clamps will not be acceptable for final adjustment. The design of the mechanism shall be such that the main blades are positively toggled when in the fully open or fully closed position. The outboard or offset bearing of each mechanism shall include: a cast-metal or fabricated steel housing and crank arm, a steel shaft, and either ball or roller bearing.

The location of the operating mechanisms shall be on the “outside” end of the support structure as viewed from the hinged side of the disconnect switch, as specified in Tables A, B & C
