AbolishedTest methods for electrical properties of electric cables and wires - Part 11: Test for dielectric dissipation factor
电线电缆电性能试验方法 第11部分：介质损耗角正切试验
Application Summary AI generated
This standard specifies the test method for measuring the dielectric dissipation factor (tan δ) of electric cables and wires. It is applied in the manufacturing and quality inspection of power cables, communication cables, and insulated wires to evaluate insulation performance and material aging. The test is critical for high-voltage cable applications where low dielectric loss is required for efficient power transmission and long-term reliability.
