Railway applications. Fixed installations. Electric traction. Specific requirements for composite insulators used for overhead contact line systems1 Scope This International Standard specifies characteristics for composite insulators of electric traction overhead contact line systems for railways, as defined in IEC 60913. Insulators specified in this standard are applied for electric traction supply voltages with a nominal voltage greater than 1 000 9 for a. c. or a nominal voltage greater than 1 500 9 for d. c.. Specific applications where high torsional loads can occur are outside the scope of
