More Information
Summary:The utility model relates to a high-voltage large-current alternating-current withstand voltage test wire which is a coaxial cable consisting of an external sheath layer, copper mesh layers, a support layer and a copper stranded wire from exterior to interior, wherein the copper mesh layer at two ends of the test wire is connected with the copper stranded wire. By adopting the coaxial cable which consists of the external sheath layer, the copper mesh layers, the support layer and the copper stranded wire, not only the corona can be effectively avoided, but also the quality factor of a series resonance loop is improved, thereby perfectly solving the problem that the test value is substandard when the test current is large under the state of high voltage, and being reliable in installing and long in service life.
