How to deal with the burning out of heating pads

In the face of malicious competition from peers in terms of price, professional manufacturers of Teflon wires still maintain a strong upward trend in performance, relying not on good quality and low price, but on timely delivery, high-quality service, excellent quality, and good customer reputation. Among these peers today, the advantage of competitors is the bottom price model, which harms others but not themselves. Since February 2017, there have been more than 20 peers of customers, with their development focus on the company, and the company has also actively cooperated to solve all customer problems. The main problems are: the heating element is burnt out, burned through, caught fire, temperature is out of control, poor joints, heating wires are easy to break, and cannot meet UL bending standards. It is really easy to make a product, but it is difficult to make a good product. With a future oriented approach, our company has won the attention of customers and gained market initiative by sacrificing quality and quantity. In the future, our company will respond to more serious market challenges with the same operating mode and continuous innovation spirit!

[Process Technology] What are the issues that should be paid attention to during power cable construction

1. Eddy current problems caused by high current power cables During the construction of power cables, there are steel supports, steel protective pipes, and cable clamps and overhead laying. Any steel (iron) closed loop formed around the power cable may form eddy currents, especially in high current power cable systems, where the eddy currents are larger. During the construction of power cables, measures must be taken to prevent the formation of steel (iron) closed loops around the cables and prevent the occurrence of eddy currents caused by the cables. 2. Mechanical damage caused by turning of power cables Due to the large outer diameter of power cables, it is difficult to transport and lay them, and the requirements for turning radius of power cables are also relatively strict. During the construction of power cables, if the turning angle is too large, it may cause mechanical damage to the inside of the conductor, and the mechanical damage may be reduced by the insulation strength of the cable until a fault occurs. During the construction, a cable head fault was found. During the production of the cable head, the three cable heads were of the same length, and when connected to the equipment, due to terrain constraints, the middle phase cable head was too long and became arched, causing damage and discharge at the root of the cable head. After that, measures were taken to appropriately shorten the connection length of the middle phase cable head during the connection of the equipment, so that the three-phase cable head would not be subjected to external forces. Practice has proven that the operation effect is good. It can be seen that during cable construction, it is necessary to minimize the torsion on the cable. When the cable is turned and the cable is reserved, the cable should be kept in natural bending to prevent internal mechanical damage. 3. It's a moisture proof problem for power cables Operating experience has shown that most of the failures of medium and low voltage power cables are caused by cable intermediate joints and terminal heads, while most of the failures of intermediate joints and terminal heads are caused by poor sealing and moisture intrusion, resulting in a decrease in insulation strength. Medium and low voltage power cable networks mostly use dendritic power supply, with a large number of cable terminal heads, Therefore, properly sealing the cable terminal and intermediate joint is one of the important measures to ensure the safe and reliable operation of the cable. 4. It is the grounding problem of medium and low voltage power cables In public medium and low voltage power cable networks, because three-phase loads are not equal, if a cable with a metal protective layer is used, the grounding of the metal protective layer must be considered, and the normal induced voltage at any point of the metal protective layer that is not grounded must not be greater than 100 V. I believe that in medium and low voltage cable networks, all cable joints should be provided with grounding electrodes (grids), and the metal protective layer should be reliably grounded.

Prevention of fire and electric shock risk New standard for electric vehicle charging cables released

On June 22, a fire accident occurred on a hybrid bus in Xiamen, causing 11 buses to be burned down and one person to die. According to police investigations, it was determined that an electrical failure in the battery pack at the rear of a bus caused spontaneous combustion, which quickly spread and caused other buses parked in the same row to burn. In addition, the recent Wuzhoulong electric bus fire incident in Shenzhen and Nanjing electric bus fire incidents have caused public concern about the safety of new energy vehicles. How to avoid similar accidents? In addition to strengthening product quality assurance for electric vehicle enterprises, various technical standards in this new field must also be established. Wu Changshun, director of the National Center for Wire and Cable Quality Supervision and Inspection (hereinafter referred to as TICW), said that traditional vehicles have safety level cable standards, but entering the era of electric vehicles, these standards cannot fully guarantee the safety of electric vehicles. Due to changes in the power system of electric vehicles, the voltage and current transmitted by relevant wires and cables are completely different from those of traditional vehicles. If the wire and cable standards of traditional vehicles are still adopted, the probability of fire and electric shock accidents will greatly increase. Therefore, recently, TICW, in conjunction with the China Quality Certification Center (CQC) and German DeKRA Quality Certification Co., Ltd. (DEKRA), jointly issued the "Electric Vehicle Charging Device Equipment Cable Standard K175/CQC1103-1105". In the future, new standards for electric vehicle wires and cables will be developed and released in succession to promote the safety and convenience of electric vehicle wires and cables. In the future, if there is a safety liability accident for electric vehicle charging piles, relevant responsibilities can also be identified and investigated based on the standards. Xie Zhiguo, Deputy Director of the Fourth Product Certification Department of the China Quality Certification Center (CQC), stated to the First Electric Network that the interface standard for electric vehicle charging piles has currently been released in 2011, and the recently revised version of the new national standard has been completed, and will soon be released in 2015 or 2016. The release of this national standard is mainly aimed at solving the compatibility and safety issues of electric vehicles and charging piles in the future. However, there are also wires and cables at both ends of the charging interface. The revision process of the new national standard for charging interfaces has also consulted the relevant standards for wires and cables, because the real risk of electric vehicle fire and electric shock is not only related to the interface, but also an important link, especially DC high-voltage fast charging, The charging current is much higher than the current transmitted by ordinary electrical wires and cables, so if the cable does not meet the standard, it is likely to cause a fire accident. Therefore, the electric vehicle charging cable standard launched first this time will incorporate charging pile cables into a standard system from the aspects of safety and testing standards, which can not only provide manufacturers with a unified standard as a reference, but also guarantee quality and safety. Currently, most electric vehicle charging pile cables on the market are orange, so will orange become the unified standard in the future? Ms. Liu Weihai, Director of Electric Vehicle Components and Special Cables for Greater China at Dekai Quality Certification (Shanghai) Co., Ltd., said that the original color requirement for vehicle charging cables in the wire and cable standards was orange, but there was no clear requirement for the color of charging pile cables, except that everyone habitually followed the orange design. In fact, there are also black and dark blue charging pile cables on the market, but the number is relatively small. It is estimated that cables of various colors may appear after a large number of charging piles appear in the future.
