GB/T 17737.106 - 2018 Focused coaxial communication cable electrical test, dedicated to the cable jacket voltage resistance test. It specifies the applicable cable type and specification range, and specifies the requirements of voltage resistance test equipment in detail, such as the parameters of high voltage generators. Specify the test steps, including sample preparation, the way of applying voltage, voltage value and duration setting, etc. Through this test, the insulation performance of the cable jacket under high voltage can be inspected. It provides a key basis for cable manufacturers to control the mass of products and communication engineering builders to evaluate cable safety. Ensure that coaxial communication cables transmit signals safely and stably in complex electrical environments.
