Abstract

This specification covers ozone-resistant thermoplastic elastomer insulation for electrical wires and cables operating continuously at specified conductor temperatures, within the specified voltage range, and under wet or dry conditions. The prescribed tests cannot be performed unless the insulation is formed around a conductor, but these are done solely to determine the insulation properties and not to test the conductor or completed cable. Each test sample should be subjected to ac and dc voltage withstand tests as well as insulation resistance tests and should comply with the required values for aging, heat distortion, electrical permittivity, increase in capacitance, stability factor, and accelerated water absorption.

Scope

1.1 This specification covers an ozone-resistant insulating compound for electrical wire and cables 14 AWG and larger. This compound consists substantially of a thermoplastic elastomer.

1.2 This type of insulation is suitable for continuous operation at conductor temperatures not exceeding 90°C in dry locations and 75°C in wet locations. Operating voltages are not to exceed 2000 V. The minimum installation temperature is 40°C.

1.3 Whenever two sets of values are presented, in different units, the values in the first set are the standard, while those in parentheses are for information only.

1.4 In many instances the insulation material cannot be tested unless it has been formed around a conductor or cable. Therefore, tests are done on insulated wire or cable in this document solely to determine the relevant property of the insulation material and not to test the conductor or completed cable.
