This is the second edition of CSA C411.5, Dead-end\/suspension composite insulators for overhead lines = 75 kV. It supersedes the previous edition published in 2010.<\/p>\n
This Standard is based on the requirements of Canadian Electricity Association (CEA) LWIWG-01 (96), Dead-End\/Suspension Composite Insulator for Overhead Distribution Lines (used with permission from CEA). <\/p>\n
1.1<\/p>\n
This Standard covers the requirements for dead-end\/suspension composite insulators used on overhead distribution lines operating at nominal voltages up to and including 75 kV. Dead-end insulators support the line conductor horizontally. Suspension insulators support the line conductor vertically. Both are subjected to tensile and torsional loads.<\/p>\n
These composite insulators are intended to operate in a service environment within a temperature range of %u201350 to 50 \u00b0C.<\/p>\n
The main objective of this Standard is to define terms, prescribe test methods, and recommend acceptance or failure criteria. Clauses 4 to 8 specify the material, product qualification, construction and test requirements applicable to these insulators. Annexes D, E, and F provide examples of design, type, and sample\/routine test reports.<\/p>\n
1.2<\/p>\n
This Standard deals with composite insulators having a core with metal fittings and a housing and sheds. The core has resin-impregnated glass fibres. The housing and sheds consist of elastomers (e.g., silicone, ethylene propylene). The metal fittings are aluminum, steel, or iron.<\/p>\n
1.3<\/p>\n
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.<\/p>\n
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.<\/p>\n
Notes to tables and figures are considered part of the table or figure and may be written as requirements.<\/p>\n
Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.<\/p>\n","protected":false},"excerpt":{"rendered":"
