How to perform high-voltage cable branch box inspection? What are the testing standards and items? Today, BAIJIAN will introduce the relevant content of high-voltage cable branch box testing to everyone
High voltage cable branch boxes have become a major challenge in the 10kV distribution network cabling project of the power system, replacing a large number of branches in the original overhead lines with an economical, reliable, and easy to maintain wiring method. The emergence of cable branch boxes has completely solved this problem, and its fully insulated and fully sealed characteristics greatly reduce the line failure rate, making it the preferred equipment for distribution network cabling projects Its simple, convenient, and flexible connection and combination method makes it possible to replace ring network cabinets in certain situations; When necessary, it can be buried underground or immersed in water, saving investment in equipment and cables, improving the reliability of power supply, and is widely used in commercial centers, industrial parks, and densely populated urban areas. Cable branch boxes can be divided into three types according to their structural form and types of cable joints: American type cable branch boxes, European type cable branch boxes, and cable branch boxes with switches What is the testing fee The specific cost of testing high-voltage cable branch boxes 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
