1、ANSI CL35=22 88 W 0724350 0504685 897 ANSI C135.22-1988 American National Standard for zinc-coated ferrous pole-top insulator pins with lead threads for overhead line construction Approved March 2, 1988 Secretariat: National Electrical Manufacturers Association ) 1 Scope and application 1.1 Scope Th

2、is standard covers ferrous pole-top insulator pins with 1 -inch- and 1 -3/8-inch-diameter lead threads used in overhead line construction. 1.2 Application Pins conforming to this standard shall, in all respects, meet the dimensional and perfor- mance requirements hereinafter stated. The text, specif

3、ications or standards references, and associated figures supplement each other and shall be considered as parts of this stan- dard. 2 Normative references The following standard contains provisions which, through reference in this text, constitute provisions of this American National Standard.

The coating shall be applied by: - the hot-dip process in accordance with ANSVASTM A-153-82; or - another method producing a zinc coating that meets the requirements of ANSVASTM A-153-82 for adhesion,

18、 purity, and thickness applicable to the class of material being coated. 7 Finish Pins shall be reasonably smooth on all surfaces and free of sharp projections. 8 Marking of pins Pins shall bear the manufacturers symbol or identification mark. 9 Protective packing Lead threads shall be protected wit
