Each switch consists of three or more packaged items; the control parts box, the switch units, a bundle of pipe and the insulators when not assembled to the switch. Check packing list, attached to the switch crate, to determine if all material has been received. Check insulators carefully for cracked or broken porcelain. Check all other materials for possible shipment damage or loss. Report any claims to the carrier.
7.5 thru 46kV switch units are shipped completely assembled with insulators unless specified otherwise by the purchaser.
69kV thru 230kV switch units are shipped assembled, less insulators, unless specified by the purchaser or switch construction necessitates the complete assembly.
Installation instructions and print of control arrangement are packed in the control parts box in a plastic envelope. Check bill of material on control print and material received. Notify factory of any missing parts.
All switch units have been adjusted at the factory for proper contact pressure, proper opening angle, etc. and no field adjustments of the live parts are required.
