38、to effect on 31 May 2009. It was prepared by Technical Committee PEL/11, Overhead lines. A list of organizations represented on this committee can be obtained on request to its secretary.SupersessionThis part of BS 3288 supersedes BS 3288-2:1990, which is withdrawn.Information about this documentThi
39、s is a full revision of the standard, and introduces the following principal changes. Errors in figures and tables identified in the previous edition have been corrected and proposed amendments where appropriate included. Where fittings were previously shown with a clevis pin, washer and split pin,
40、a hex. bolt, nut and split pin is now shown in accordance with the current UK industry preferred practice, and the suffix “A” has been added to the reference number. The option of using a clevis pin, washer and split pin has, however, been retained. A number of new insulator fittings that are in com
41、mon use have been included, for example; 70 kN socket thimbles, 70 kN and 125 kN cranked/parallel links, 300 kN and 400 kN ball-clevis/clevis-tongue fittings, 190 kN and 300 kN yoke plates, 300 kN and 400 kN sag adjuster sets. Some insulator fittings that have become obsolete, or have limited use, h
42、ave been excluded.NOTE This standard sets out to cover the more common insulator fittings in use. It is not practical to include every type of insulator fitting as the range is too extensive.Presentational conventionsThe provisions of this standard are presented in roman (i.e. upright) type. Its req
43、uirements are expressed in sentences in which the principal auxiliary verb is “shall”.Commentary, explanation and general informative material is presented in smaller italic type, and does not constitute a normative element.Contractual and legal considerationsThis publication does not purport to inc
44、lude all the necessary provisions of a contract. Users are responsible for its correct application.Compliance with a British Standard cannot confer immunity from legal obligations.BS 3288-2:2009vi BSI 2009BRITISH STANDARDThis page deliberately left blankBRITISH STANDARD BSI 2009 1BS 3288-2:20091 Sco
