Pin type insulator ANSI 56 standard parameter of C29.6
Pin type insulator ANSI 56 consists of a single piece of ceramic or maybe two pieces of ceramic components permanently assembled together by cement. Porcelain pin type insulator is mounted rigidly on a supporting structure by an insulator pin or insulator spindle. Unless otherwise stated, this term does not include the insulator pin.

Power frequency dry flashover voltage of pin type insulator ANSI 56: ANSI 56-1 is 95KV; ANSI 56-2 is 110KV; ANSI 56-3 is 125KV; ANSI 56-4 is 140KV; ANSI 56-5 is 175KV.
Power frequency wet flashover voltage of pin type insulator ANSI 56: ANSI 56-1 is 60KV; ANSI 56-2 is 70KV; ANSI 56-3 is 80KV; ANSI 56-4 is 95KV; ANSI 56-5 is 125KV.
Radio influence test voltage to ground of pin type insulator ANSI 56: ANSI 56-1 is 15KV; ANSI 56-2 is 22KV; ANSI 56-3 is 30KV; ANSI 56-4 is 35KV; ANSI 56-5 is 44KV.
Dry arcing distance of pin type insulator ANSI 56: ANSI 56-1 is 178mm; ANSI 56-2 is 203mm; ANSI 56-3 is 229mm; ANSI 56-4 is 279mm; ANSI 56-5 is 356mm.
Each insulator, including ANSI 56-1, 56-2, 56-3, 56-4, 56-5 pin type insulator, shall bear a symbol identifying the insulator manufacturer. The marking shall be legible and durable.
