ANSI 57-2 porcelain line post insulator,line post insulator parameters

ANSI 57-2 porcelain line post insulator is made of good commercial-grade wet-process porcelain as per line post insulator parameters. Like other tie-top line post insulator products, it is used with long spindle or short spindle.

ANSI 57-2 porcelain line post insulator applied standards:
When the following American National Standards referred to in this document are superseded by a revision approved by the American National Standards Institute, Inc. the revision shall apply:
ANSI C29.1-1988, test methods of electrical power insulators
ANSI Z55.1-1967(R1973), American National Standard Gray Finishes for Industrial Apparatus and Equipment
ANSI A153-82, parameter for zinc coating (hot dip) on iron and steel hardware
