How to detect low-voltage power cables? What are the testing standards and items? Today, BAIJIAN will introduce the relevant content of low-voltage power cable testing to everyone
A cable is a conductor covered with an insulation layer, protective layer, shielding layer, etc., used to transmit power or signal current, signal voltage, etc. According to voltage, it can be divided into high-voltage cables and low-voltage cables. Compared with low-voltage overhead lines and low-voltage overhead insulated lines, low-voltage cable lines have higher costs and are more difficult to lay and maintain. However, due to their reliable operation, no poles, no floor occupation, unobstructed view, and less external influence, they are widely used in low-voltage distribution systems What is the testing fee The specific cost of low-voltage power cable testing is determined based on factors such as testing items and laboratory qualifications. BAIJIAN will arrange engineers to confirm the relevant testing content with you before making a quotation
