Specifies requirements for porcelain stay insulators consisting of one part, with two transverse holes for the insertion of stay wires used for poles supporting overhead power lines, operating at greater than 1000 volt a.c. Dimensions and mechanical performance are specified.

This Standard specifies requirements for porcelain stay insulators as defined in Clause 1.3.1 and which are incorporated with the stay wires used for poles supporting overhead lines.NOTE: Appendix B lists information that should be specified by the purchaser of the insulators.
