Standard Specification for Poly(Vinyl Chloride) Insulation for Wire and Cable, 90 °C Operation
ABSTRACT
This specification covers poly(vinyl chloride) thermoplastic insulation for conducting wires and cables operating continuously at a specified conductor temperature, within the specified voltage range, and under wet or dry conditions. The insulation has potential low-temperature installation limitations. 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 an ac and dc voltage withstand tests and insulation resistance test and should comply with the required values for unaged and aged requirements of tensile strength and elongation at rupture, heat shock, heat distortion, vertical flame test results, oil resistance, and cold bend test results. All joints and repairs in the insulation should be done in such a way as the affected parts meet the same electrical requirements as the rest of the insulation.
SCOPE
1.1 This specification covers a thermoplastic insulation of poly (vinyl chloride) or the copolymer of vinyl chloride and vinyl acetate. This insulation is recommended for use at conductor temperatures not in excess of 90 C.
1.2 Depending on the thickness of the insulation, the maximum voltage used, and whether the location is wet or dry, this insulation is acceptable for use in 300 V (dry) and 600 V (wet or dry) power and control circuits.
1.3 This insulation has potential low-temperature installation limitations. Consult the manufacturer for specific recommendations for installation.
1.4 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.
1.5 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 specification solely to determine the relevant property of the insulation material and not to test the conductor or completed cable.
