CSA C411.7-16 Composite insulators for guy wires
: Brown Technical Book Store
This is the second edition of CSA C411.7, Composite insulators for guy wires. It supersedes the previous edition, published in 2011. This Standard is based on the requirements of Canadian Electricity Association (CEA) LWIWG-03 (96), Guy Composite Insulator for Guy Wires (used with permission from CEA). The co-operation of CEA and the contribution of its members are gratefully acknowledged. Scope 1.1 This Standard covers the requirements for guy composite insulators used in guy wires on overhead distribution lines operating at nominal voltages up to and including 75 kV. Guy insulators insulate or isolate guy wires for corrosion protection, higher insulation levels, clearances for maintenance and normal operation, and safety for the public and workers (joint-use). Guy composite insulators are subjected to tensile and torsional loads. The composite insulators are intended to operate in a service environment within a temperature range of - 50 to 50 Â°C.
