Licheng: MYJV cable 6/10kv1x70 long-term stock

with the vigorous development of the domestic high-voltage cable market, the production technology of high-voltage cable has been basically mature and has generally realized localization. However, the core material for manufacturing high-voltage cables, high-voltage insulating materials, is still completely dependent on imports, and has been in an embarrassing situation of short supply and controlled by others for a long time

recently, relevant electric power institutions and experts organized the evaluation and demonstration meeting of localized high-voltage insulating materials to conduct on-site evaluation and demonstration of Wanma polymer high-voltage insulating materials project, so as to determine the technology and industrialization level of localized high-voltage insulating materials. The evaluation and demonstration results show that Wanma polymer has achieved the localization of 110 kV high-voltage cable insulating material. The main production method of the product is to synthesize through chemical raw materials, which can reach the international advanced level. The product filling and quality level can fully meet the manufacturing and operation requirements of high-voltage cables. Recently, the key project Wanma polymer high voltage cable (110kV) ultra clean XLPE insulating material production line (with an annual capacity of 20000 tons) undertaken by Zhejiang Wanma polymer materials Co., Ltd. (hereinafter referred to as "Wanma polymer") has been officially put into operation. Various signs show that the localization of high voltage cable insulating material is coming

localization of high-voltage insulating materials breaks the foreign monopoly

"at present, the domestic high-voltage insulating material market is basically monopolized by two foreign companies, which is completely incompatible with the image of China as a major cable manufacturer." Wu Changshun, deputy chief engineer of Shanghai Cable Research Institute, told China power news that if the embargo or sales ban occurs for some reason, it will have an incalculable impact and loss on China's cable industry and power transmission industry, as well as national defense and national economic construction and development

from this point of view, the localization of high-voltage cable insulating materials is imperative. China's economic aggregate, technical level and material consumption also have the conditions for localization

power cables with voltage levels of 110 kV and above are called high-voltage cables. Because they operate under high voltage conditions of 110 kV and above, the requirements for insulating materials are relatively high. In order to prevent cable breakdown under high voltage, cable insulating materials must be super clean

then, can domestic high-voltage insulating materials meet the requirements of manufacturing high-voltage cables? In order to break the monopoly of foreign manufacturers and develop national industries, Wanma polymer, as a leading enterprise in the domestic industry, has increased its R & D investment in the field of high-voltage insulating materials, overcome the technical problems that restrict the domestic development of high-voltage cable insulating materials, successfully developed the process formulation technology suitable for high-voltage cable insulating materials, and the process technology suitable for the production of high-voltage cable insulating materials - post absorption process, which has obtained relevant national invention patents. In order to meet the high standard requirements for quality, equipment accuracy and production environment in the production of high-voltage insulating materials, Wanma polymer has customized and imported a complete set of high-voltage insulating material post suction production equipment from abroad according to the technical requirements of high-voltage insulating materials, realizing the localization of high-voltage cable insulating materials

Licheng: during the long-term storage and transportation of MYJV cable 6/10kv1x70, it is strictly forbidden to drop the cable or the cable reel containing the cable from a high place, especially at a low temperature (generally about 5 ℃ and below), throwing and dropping the cable may cause the insulation and sheath to crack. Try to avoid storing cables in the open air, and the cable reel is not allowed to be placed horizontally. When hoisting packages, it is strictly forbidden to hoist several plates at the same time. On vehicles, ships and other means of transportation, the cable reel with the specific energy of power battery cells reaching more than 300 watt hours/kg should be fixed with appropriate methods to prevent mutual collision or overturning. Generally speaking, to prevent mechanical damage to the cable. Cables are strictly prohibited from contacting with acids, alkalis and mineral oils, and should be stored separately from these corrosive substances There shall be no harmful gas damaging insulation and corroding metal in the warehouse where cables are stored. During the storage period, the cable should be rolled regularly (once every three months in summer, and can be extended as appropriate in other seasons). When rolling, roll the side of the storage tray downward and upward to prevent the bottom from being damp and rotting. Always pay attention to whether the cable head is intact during storage. The storage period of cables is limited to the ex factory date of products. Wire and cable products that meet the requirements of national standards, whether aluminum or copper conductors, are relatively bright and oil-free, so the DC resistance of the conductor fully meets the national standards, with good conductivity and high safety. Length is the main intuitive method to distinguish between meeting the requirements of national standards and counterfeiting. Don't be greedy for bargains when shopping. Choose wires and cables whose actual meters are lower than their nominal meters. The length must be consistent with the nominal number of meters. The state stipulates that the allowable error per 100 meters is ± 0.5 meters. What kinds of wires and cables are commonly used according to their purposes? Answer: according to the purpose, it can be divided into bare wires, insulated wires, heat-resistant wires, shielded wires, power cables, control cables, communication cables, RF cables, etc. What kinds of insulated wires are there? Answer: there are several kinds of commonly used insulated wires: PVC insulated wires, PVC insulated flexible wires, PVC mixture insulated wires, rubber insulated wires, agricultural underground directly buried aluminum core plastic insulated wires, rubber insulated cotton yarn textile flexible wires, PVC insulated nylon sheathed wires, PVC insulated flexible wires for power and lighting, etc. The demand for wires and cables will also grow rapidly, and the wire and cable industry has great development potential in the future. Workshop is the basic layer of an enterprise. How to strengthen the management of grass-roots units? The following "ten haves" requirements are put forward. Positions: according to the specific tasks undertaken by the mobile phone of the car: 18901259439, the positions clarify the work tasks and the primary and secondary responsibilities of the personnel in each position in the workshop in the form of work standards or operation standards, establish a scientific and clear system, and clarify the corresponding accountability system. Planned work: the work of the workshop has a clear plan, and the objectives, personnel, time, measures, etc. are specific and clear, which fully reflects the policies, objectives and plan requirements of the company and the unit. Management system: the workshop can establish and improve the management system in line with the actual situation of the workshop according to the management systems of the company and the unit, and meet the scientific, standardized, systematic and effective requirements. There are standards for operation: guide the staff to operate correctly in the workshop, including "post work standards", "post work standards" and various procedures
