CSA C22.3 No.1-2020 架空系统

1 Scope 1.1 This Standard applies to electric supply and communication lines and equipment located entirely outside of buildings and fenced supply stations and buildings, and also where the installations or equipment are inside buildings or sections of buildings where they are employed by a utility of a) an electric system; b) a communication system; or c) a community antenna distribution system in the exercise of its function as a utility. 1.2 Existing installations meeting the requirements of prior editions of this Standard need not be modified to comply with this edition of the Standard, except as might be required for safety reasons by the authority having jurisdiction. 1.3 This Standard, which forms part of the Canadian Electrical Code, Part III, provides requirements for the construction of overhead systems. It covers electric supply and communication circuits that a) are installed alone; b) are in joint-use; c) are in proximity to each other or other facilities; d) cross each other or other facilities; and e) cross railways, highways, navigable waterways, or land that is likely to be traversed by vehicles or pedestrians. 1.4 This Standard presents a choice between deterministic and reliability-based design methods. Reliabilitybased design methods are covered by CSA C22.3 No. 60826. 1.5 The requirements contained in this Standard do not constitute complete design and construction specifications, but rather prescribe the minimum design requirements that are most important to the a) safety of persons; b) continuity of service; and c) protection of property. 1.6 Conditions not covered by this Standard are governed by equivalent Standards in common use or by the authority having jurisdiction. 1.7 In some cases in this Standard, specific types of construction are envisaged. This does not preclude the use of other types of construction, provided that the engineering representatives involved can demonstrate the safety and suitability of these alternatives. 1.8 The use of terms such as “where practicable” is not intended to provide an opportunity for not meeting the requirements of this Standard, but indicates the preferred clearance or method. Where an alternative is not specified, the engineering solution that most closely adheres to the preferred method should be used. 1.9 Where the requirements of more than one clause apply, all should be satisfied. 1.10 In this Standard, “shall” is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the Standard; “should” is used to express a recommendation or that which is advised but not required; and “may” is used to express an option or that which is permissible within the limits of the Standard. Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material. Notes to tables and figures are considered part of the table or figure and may be written as requirements. Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.

ASTM B987/B987M-20 用于架空电导体的碳纤维热固性聚合物基复合材料芯（CFC）的标准规范

1.1 This specification covers carbon fiber reinforced thermoset matrix composite core strength members for use in reinforcing or supporting overhead electrical conductors. 1.2 This specification covers carbon fiber core diameters from 0.180 to 0.500 in. [4.57 to 12.7 mm], inclusive. 1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
