Connecting the High-Voltage Conductors
STEP 29. When high-voltage conductors are to be
connected using aluminum-alloy body
connectors
● the following procedures should
be used:
(a) Thoroughly wire-brush the current-transfer
surfaces of each connector and immediately
apply a liberal coating of Penetrox® A to the
brushed surfaces.
(b) Wire-brush each terminal pad of the interrupter
switch and apply a coating of Penetrox A. Then,
bolt the connectors to the terminal pads.
(c) Prepare the conductors using established
procedures and clamp them in their respective
connectors.
● “Mass anode”-type connectors, such as the catalog number 5300
series offered by S&C, designated by the connector manufacturer as
