This Standard specifies electrical and mechanical characteristics and principle dimensions for porcelain and glass insulators of the following types:(a) String insulator units of the cap and pin type.(b) String insulator units of the long rod type.(c) Line post insulators.(d) Pin insulators.For full details of the insulators covered by this Standard, reference should be made to Sections 2, 3, 4 and 5 herein.This Standard does not apply to insulators for electric traction lines which use special metal fittings.NOTE:1. Ball and socket couplings, and clevis and tongue couplings are specified in AS 2947.3.2. Manufacturers wishing to claim compliance with this Australian Standard on insulators, on packaging or on related promotional material are advised to ensure that such a claim is capable of being verified.
