适用范围：This specification covers track-resistant black thermoplastic high-density polyethylene insulation. Before application to the conductor, the insulation shall comply with the requirements of Specification D 1248, Type III, Class C, Category 5, Grade E10, J4, or J5. The requirements of Specification D 1248 shall not apply to the insulation removed from the conductor. This type of insulation is considered suitable for use on wire or cable that will be used for continuous operation at conductor temperatures up to 75 ?C. This insulation is suitable for use on wire or in cable used for power transmission in overhead spaced-line service, installed at temperatures above 25 C and exposed to sunlight and other atmospheric environments between 55 and +75 C. In many instances, the insulation cannot be tested unless it has been formed around a conductor. Therefore, tests done on insulated wire in this standard are solely to determine the relevant property of the insulation and not to test the conductor or completed cable. 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.
