ANSI 52-1 Disc Suspension Insulator

ANSI 52-1 suspension insulator definition：

ANSI 52-1 suspension insulator is different from ANSI 52-3, 52-4 suspension insulator in connecting ways, they are smaller and with different connection method. These are design according to ANSI international insulator standard and made of wet process porcelain.

Technical data of ANSI 52-1 suspension insulator

Metal parts connection method of ANSI 52-1:

clevis and ring type insulator, completed with cotter key, which can be bronze, brass, austenitic stainless steel, or aluminum.

Combined mechanical and electrical strength of ANSI 52-1 suspension insulator:

strength is 44KN, equal to 10000lb

As per standard: ANSI C29.1 and C29.2 international high voltage insulator standard

Tests or inspection of ANSI 52-1 suspension insulator:

type tests: thermal-mechanical load test, thermal shock test, residual-strength test, critical impulse flashover tests- positive and negative, low-frequency dry flashover test, low frequency wet flashover test, impact test, cotter key test, cement expansion test. radio-influence voltage test

sample test: galvanizing test, combined mechanical and electrical-strength tests, puncture tests, visual and dimensional tests, porosity test

routine test: flashover routine test and tension proof test
