Customers have seen related high-voltage cable products on our website. The customer first asked about the relevant price. The customer asked if he could visit the factory. He also has a friend on our side. He wants him to see it. Of course, he can reply. Just say hello in advance.
Then after discussing the specific logistics route, the customer was sent a catalogue of past high-voltage cable products and product information. After reading it, the customer was very interested and asked about the PVC sheath material in the high-voltage cable, and responded to the customer. PVC is polyvinyl chloride. Because of its high chemical stability, it can be used to make anticorrosive pipelines, pipe fittings, oil pipelines, centrifugal pumps and blowers. Polyvinyl chloride hard boards are widely used in the chemical industry to make linings for various storage tanks, corrugated boards for buildings, door and window structures, wall decorations and other construction materials. Due to its excellent electrical insulation performance, it can be used to manufacture plugs, sockets, switches and cables in the electrical and electronic industries. In daily life, PVC is used to make sandals, raincoats, toys and artificial leather.
The customer asked what to do with this after-sales service. We responded to the customer with one-year after-sales service. If it is damaged, it can be sent back for repair. As long as it is used properly, the product itself will not have any major quality problems. Then I reminded customers that there are many examples of high-voltage cable system failures due to construction quality. The main reasons are the following: First, the site conditions are relatively poor. The high-voltage cables and connectors are manufactured in the factory with high environmental and technological requirements, and the construction site Temperature, humidity, and dust are not easy to control. Second, during the construction of high-voltage cables, small slip marks will inevitably be left on the insulating surface. Semi-conductive particles and sand on the emery cloth may also be embedded in the insulation. In addition, the insulation will be exposed to the air during the joint construction process. Inhalation of moisture, these will leave hidden dangers for long-term safe operation. The third is that the installation process did not strictly follow the process construction or process regulations without considering possible problems. Fourth, the use of DC withstand voltage test for completion acceptance results in the formation of a back electric field in the joints, which leads to insulation damage. Fifth, it is caused by improper sealing treatment. The intermediate joint must adopt a sealing structure with a metal copper shell and a PE or PVC insulating anticorrosion layer to ensure the tightness of the lead seal during on-site construction, which effectively guarantees the sealing and waterproof performance of the joint.
