Firstly, the high-voltage cables of new energy vehicles generally match the voltage level of the battery pack. According to the design of the vehicle's electrical system and voltage requirements, the appropriate voltage level is selected, for example, common high-voltage cable voltage levels are 500V, 800V and so on. Secondly, the rated current of the high-voltage cable should be able to meet the charging and driving requirements of the electric vehicle. According to the power and charging requirements of the vehicle, select the high-voltage cable with sufficiently large rated current capacity to ensure charging efficiency and driving performance. The insulation material of the high-voltage cable should have good insulation and high temperature resistance to prevent current leakage and short-circuit accidents. Commonly used insulating materials include polypropylene, polyethylene and cross-linked polyethylene. According to the use environment and temperature requirements of the vehicle, choose the appropriate insulation material. In addition to this, high-voltage cables are subject to friction, extrusion and environmental climate during use. Therefore, high-voltage cables with good abrasion and weather resistance should be selected to extend their service life and reliability. When selecting high-voltage cables, it is important to choose the appropriate length of high-voltage cable according to the design and layout of the vehicle and to ensure that the connection method and connectors meet the requirements of the vehicle system. Suitable lengths and connections simplify the installation process and increase the reliability of the cable. It is important to ensure that the cables comply with relevant safety certification standards and regulations, such as national or regional product certifications, International Electrotechnical Commission (IEC) standards, etc. These certifications guarantee the quality and safety performance of high-voltage cables.

In the field of power transmission, high-voltage cables are an indispensable component. The selection of insulation materials for high-voltage cables is crucial for power transmission. In this paper, we will focus on the common insulation materials and their characteristics of high-voltage cables, and analyze the advantages and disadvantages of different types of insulation materials by comparing and contrasting them, and make an in-depth analysis from the perspectives of material properties and applicable scenarios. First, let's take a look at polyvinyl chloride insulated power cables. As a common insulating material, PVC has good heat resistance and corrosion resistance, and is suitable for power transmission under various environmental conditions. The nominal thickness of its insulation can also effectively prevent current leakage and improve the safety of the cable. However, PVC insulated power cables also have some disadvantages, such as easy deterioration in high temperature environments, and need to be replaced periodically to ensure the stability of power transmission. Another common insulating material is cross-linked polyethylene. Compared with PVC, cross-linked polyethylene has higher heat and voltage resistance and is suitable for high-voltage power transmission. Its insulating properties are stable, and it is not easy to deteriorate in long-term use, making it an excellent insulating material. However, cross-linked polyethylene is relatively expensive and needs to be selected according to specific scenarios. When selecting insulation materials for high-voltage cables, various factors need to be considered according to the actual power transmission scenario. The properties and application scenarios of different insulating materials differ significantly, so it is crucial to choose the right insulating material. Only after a full understanding of the advantages and disadvantages of various insulating materials, and according to the specific needs to choose, can ensure the safety and stability of power transmission. In summary, the selection of insulation materials for high-voltage cables has an important impact on power transmission, and it is crucial to choose the right insulation materials for different scenarios. Only by choosing under a professional, objective and analytical perspective can we ensure the smooth progress of power transmission. We hope that this article can help you better understand the insulation materials of high-voltage cables and provide some reference for the development of the power transmission field.
The standards for high voltage cables for electric vehicles cover a number of aspects to ensure that the cables can work safely and stably in high voltage and high current environments. Here are some interpretations of the standards for high voltage cables for electric vehicles: Voltage Requirements: According to the voltage level of electric vehicles, the rated voltage of the whole vehicle is usually DC1000V or AC660 V. The rated voltage of the high-voltage wiring harness shall be slightly higher than the rated voltage of the whole vehicle, so as to ensure that it can work stably under all kinds of working conditions. Voltage resistance: The cable should be able to withstand high voltage testing to verify its dielectric strength. In the case of the harness and components off, the harness to the car body should be able to withstand a certain voltage and frequency of the test, without breakdown. Insulation resistance: Insulation resistance is an important indicator of the insulation performance of cables. According to the standard, the insulation resistance of the cable should be greater than a certain value under a specific test voltage to ensure that the cable will not leak or short-circuit when working. Salt spray requirements: the cable should also pass the salt spray test to verify its corrosion resistance in harsh environments. After a certain period of time in the salt spray test chamber, the cable should be able to work normally without performance degradation or appearance damage. In addition, the standard for high-voltage cables for electric vehicles also involves the structural design, material selection and manufacturing process of the cable. The conductor cross-section, conductor materials, insulation materials, shielding layer, etc. of the cable need to meet the relevant requirements to ensure the performance and safety of the cable. Overall, standards for high voltage cables for electric vehicles are key to ensuring that cables can work safely and stably in high voltage and high current environments. These standards not only cover the basic performance requirements of the cables, but also include the testing requirements of the cables under various extreme conditions to ensure that the cables can meet the needs of electric vehicles in actual use.OMG' is certified by the ISO 9001:2015 and IATF 16949:2016 systems, and OMG' in-vehicle High-voltage cable products implement international standards such as ISO6722-1, ISO6722-2, ISO14572, LV216, ISO19642, UL758 (UL3820\UL30088), etc. It also widely produces Chinese standard products mainly based on QC/T1037, and on the basis of which, it also introduces enterprise standards which are higher than the industry standards.

The insulating material of high-voltage cables has a decisive influence on the safety and efficiency of power transmission. The following is an analysis of two common insulation materials: 1. Polyvinyl chloride (PVC) insulated power cables: Â Advantages: Good heat and corrosion resistance, suitable for a wide range of environments. The nominal thickness prevents current leakage and improves safety. Â Disadvantages: Easy to deteriorate under high temperature environment, may need to be replaced periodically. 2. Cross-linked polyethylene (XLPE): Â Advantages: Higher heat resistance and voltage resistance, suitable for high voltage power transmission. Stable insulating properties, not easy to age in long-term use. Â Disadvantages: Higher cost compared to PVC. The following factors need to be considered when selecting insulation materials: Environmental conditions of power transmission: e.g. temperature, humidity, chemical corrosion, etc. Operating voltage of the cable: different insulation materials are suitable for different voltage levels. Economic cost: including material cost, installation cost and maintenance cost. Long-term performance: including the aging rate and durability of the material.
