The 90kv high-voltage cable is a bridge between the power supply equipment and the power supply equipment, and plays a role in transmitting power. It is widely used, so it often fails. Therefore, we briefly analyze the causes of common problems with high-voltage cables. According to the causes of the 90kvdc high-voltage cable failure, the problems can be divided into the following categories: manufacturing reasons, construction quality reasons, design reasons by the design unit, and external force damage.
For these reasons, Newheek analyzed the matters that should be paid attention to when using 90kv high-voltage cables. First, prevent excessive bending. In addition, the bending radius of the 90kv high-voltage cable should not be less than 5-8 times the cable diameter, so as to avoid cracks and reduce the insulation strength. Secondly, keep the 90kv high-voltage cable dry and clean at ordinary times to avoid the erosion of oil, moisture and harmful gases to avoid rubber aging.
