ANSI 52-9A disc suspension insulator end fittings connection way:
ANSI 52-9A disc suspension insulator is clevis and ring type porcelain disc suspension insulator, completed with cotter key, which can be bronze, brass, austenitic stainless steel, or aluminum. This is the same with ANSI 52-1 and ANSI 52-9B.

ANSI 52-9A disc suspension insulator Combined mechanical and electrical strength is 44KN, which equal to 10000lb. Ceramic suspension insulators are designed, manufactured and tested in accordance with ANSI C29.1, C29.2, IEC 60383 standards. ANSI 52-9-A is only different from ANSI 52-9-B on ceramic shell.

ANSI 52-9A ceramic disc  insulators shall be furnished with a hump-type cotter key, whose material is critically important. The material of the cotter key is usually bronze, brass, austenitic stainless, or aluminum.
