This guide introduces the grip strength test method for fittings of high-temperature, low-sag overhead conductors with long-term operating temperature of between 90 °C and 250 °C in the co-effect of the tension and the current.
This guide provides the test methods to verify the reliability of the grip of fittings at normal temperature, at high temperature, and after high temperature cycling of high-temperature conductors with a long-term operating temperature between 90 °C and 250 °C. This guide is a resource for conductor and fitting manufacturers and installers for technical information to improve the reliability of the high-temperature, low-sag overhead conductors and electric power fittings during installation and operation.
New IEEE Standard – Active. Introduced in this guide is the grip test method for fittings of high-temperature, low-sag overhead conductor with long-term operating temperature of between 90 °C and 250 °C in the coeffect of the tension and the current.
