ASTM D1351電線和電纜用熱塑性聚乙烯絕緣材料的標準規(guī)范
ASTM D1351 Standard Specification for Thermoplastic Polyethylene Insulation for Electrical Wire and Cable
ASTM D1351電線和電纜用熱塑性聚乙烯絕緣材料的標準規(guī)范

This specification covers thermoplastic polymer insulation consisting substantially of polyethylene considered suitable for use on electrical wire or cable with specified maximum conductor sizes that will be used for continuous operation at specified conductor temperatures and maximum voltage ratings for power application or series lighting. Since the insulation material cannot be tested unless it has been formed around a conductor, tests shall then be done on insulated wire or cable in this specification are solely to determine the relevant property of the insulation material and not to test the insulated conductor or completed cable. Materials shall conform to physical properties as to unaged tensile strength and elongation at rupture, tensile strength and elongation at rupture after air oven aging, absorption coefficient, and insulation thickness. Insulations shall also be tested for their electrical performance in terms of AC and DC voltage, partial discharge, and insulation resistance.
This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
1. Scope
1.1 This specification covers a thermoplastic insulation which consists substantially of polyethylene.
1.2 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 with a maximum conductor size of 1000 kcmil (507 mm2). The maximum voltage rating shall not exceed 35 000 V for power application or 9 000 V for series lighting.
1.3 In many instances the insulation material cannot be tested unless it has been formed around a conductor. Therefore, tests done on insulated wire or cable in this specification are solely to determine the relevant property of the insulation material and not to test the insulated conductor or completed cable.
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.
