Transmission Connectors - Reference Data (TK)

Tin Plating —Tin plating can be furnished on certain connec- tors by adding suffix “GP” to the catalog number, aluminum distribution. Hardware —Anodized Aluminum Clamping Bolts are stan- dard with most Aluminum Power Connectors assembled at factory. The bolts are fabricated 2024-T4, 2014-T4 or equal aluminum and are anodized. After anodizing, the coating is sealed with a dichromate solution which imparts a yellow- green finish. Insulator attachment hardware for bus supports is galva- nized steel. Bronze Bolted Clamps Bronze bolted deadend and suspension clamps require high tensile strength and corrosion resistance in application are cast from Anderson Alloy 112 (ASTM B-30 Alloy No. C95500). The 112 alloy is a 10% aluminum, 4.5% nickel cop- per alloy with a minimum tensile strength of 90,000 PSI. Contact Sealants, Inhibitors and Joint Compounds —Various sealant formulations have been developed to provide im- proved electrical and mechanical performance as well as en- vironmental protection to the contact area. Non-petroleum base sealants areprovided for undergroundapplications and other applications where natural or synthetic rubber goods might be adversely affected. Non-gritted sealants, generally referred to as joint com- pounds, are recommended for flat connections and as a groove sealant in bolted connectors. Our gritted sealants are primarily used in compression con- nectors. Aluminum single-die compression connectors have sealant applied at the factory. Standard nuts furnished on aluminum bolts are 6061 T6 dry waxed coated.
