Preface

This is the first edition of CSA C411.5, Dead-end/suspension composite insulators for overhead lines ≤ 75 kV.

Scope

1.1
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.

These composite insulators are intended to operate in a service environment within a temperature range of -50 to 50 °C.

1.2
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.

1.3
In CSA Standards, 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 (nonmandatory) to define their application.
