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.
