GB/T 17737.105 - 2018 is part of the electrical test standard for coaxial communication cables, which is aimed at the voltage resistance test of cable media. The standard specifies the applicable cable type and specifies the specifications of professional test equipment, such as high voltage source, electrode configuration, etc. Detailed test steps, including Sample Handling, amplitude and duration of applied voltage, boost rate and other details. Through this standard test, the ability of cable media to withstand high voltage can be accurately detected. It provides a reliable basis for cable manufacturers to ensure product mass and communication industry practitioners to evaluate cable electrical performance. It ensures that coaxial communication cables transmit signals stably and are free from voltage interference.
