Precautions DC high voltage cables (1) to strengthen the cable quality inspection. Shanghai area to improve the cable manufacturing quality, to take measures to send in the factory supervision and found a lot of problems in the supervision process, received good results. (2) to improve the quality of cable installation. (3) the introduction of new test methods. When do Completion of XLPE cable test to avoid using the DC voltage can be used in series resonance or VLF method, if there is no corresponding device can also be used to run the no-load mode 24h. (4) increasing the depth of the design drawings. Is designed to guide the construction and improve the design level is the key to improving the level of cable engineering, Lanzhou wholesale high-voltage power cable, local design units should strengthen exchanges and learn to fully consider the situation in the long-term safe operation of cable systems may be encountered, Shaanxi high pressure Wholesale power cables, cable systems in order to ensure long-term safe operation efforts. (5) increase the operational monitoring efforts. Many people think that cable systems maintenance-free, high-voltage power cable wholesale, this view is wrong. High voltage power cables are divided into external damage, human factors and force majeure for two reasons, such as human dig bad cables and lightning. Second, the failure was mainly due to construction of cable laying, production, operation and maintenance and other causes, mainly in the cable sheath when laying cable breakage leads to decreased water insulation, turning radius is too small insulation damage, etc., making cable cable construction no member of the technical level of installation quality cable accessories cause decline led to lower quality cable head, the operating environment is not conducive to the cable of the cable safe operation, maintenance work is not in place is not required to cycle cable preventive tests. Cable Accessories Installation Issues: Should gravitational control tube mounting position is incorrect. After the cable production and installation problems: cable bending angle is too large. Cable running water: water in the plug-type connector. Cable Joints irrational distribution and poor operating environment, a long soak in the sewage. Gravity has water inside the tube and the insulation is aging discoloration (cable has been put into operation 15 years).
