High-voltage cable standards used in new energy heavy trucks

 Introduction: In the process of decomposition of new energy high-voltage harnesses for heavy trucks, a simple analysis of the selection of raw materials, the treatment of the shielding layer and the impact of the wire on the waterproof performance of the plug, a concise explanation of the difficulties of high-voltage wire processing, to provide some reference for the harness process designers.


High-voltage wiring harness as a new energy electric vehicle to connect the power battery, drive motor, high-voltage control system of the three core components of the link, is the medium of high-voltage power transmission, is the vehicle's power and signal transmission distribution of the highway, its quality directly affects the power or signal transmission effect and even the stability of the entire vehicle high-voltage system. Therefore, it is getting more and more attention from high-voltage wiring harness manufacturers and component suppliers. Whether it is used in electric vehicles, or heavy trucks and other vehicles, the cable manufacturing and processing process is very important.


Unlike low-voltage wiring harness systems, high-voltage wiring harness systems are used with high-voltage electricity, and the harsh application environment in the vehicle, the safety requirements are extremely high. Therefore, in the production process, the requirements of the processing process determines the performance of high-voltage wiring harness. Production process in the preparation of the following four main considerations: ① raw material selection; ② shielding layer processing; ③ quality control; ④ product application issues. In this paper, we analyze and propose solutions for the processing process according to the above four aspects.


Raw material selection: high-voltage wiring harness on the use of raw materials including high-voltage connectors, terminals, high-voltage wire, bellows, heat-shrinkable tube, shielding ring, conductive tape, etc., of which there are a wide variety of wire specifications, such as the same specifications and because of the voltage, temperature, bending radius and other factors there are large differences, so the selection of suitable raw materials for product processing is essential.


Wire selection: commonly used automotive high-voltage wire are used orange wire, cable insulation printed on the corresponding specifications and conditions of use, as well as warning signs, such as "(attention to high-voltage danger)". According to the voltage level can be divided into AC600V/DC900, AC1000V/DC1500V; commonly used wire temperature level selection 125 ℃, but also according to the use of different temperature levels such as 150 ℃, 180 ℃, 200 ℃ and other different temperature levels; for the installation of space-constrained areas can be used to bend the radius D smaller wire, such as silicone wire; according to the use of function can be Divided into shielded and unshielded cable, for the connector is different, can use single-core cable can also be used multi-core cable.

Description of cable requirements for electric vehicle charging modes

 With the development of science and technology, as a means of transportation for daily travel, cars will continue to change in the future trends. Among them, electric vehicle charging connectors and charging cables have become a trend for the development of electric vehicles. Electric vehicles generally have two charging connection methods, one is the vehicle's built-in matching charging connector, and the other is a common charging pile in public places. Compared with the charging pile that comes with the car's own charger, which charging efficiency is more efficient? First of all, compare the charging connectors of electric vehicles with charging piles: household appliances are all 220V, and the same is true for appliances with charging piles. Because the input power of the power supply is limited, it takes longer for the car to come with its own charger. On the contrary, charging piles in public places use three-phase alternating current, and the input power can reach 380V,...

Learn more about the development history of OMG cable manufacturer

 In modern society, cables play an obvious role in life. In the early 20th century: Simple cables based on copper wires began to be used for charging electric vehicles. However, the cable transmission efficiency and safety of this period were poor, making it difficult to meet the growing charging needs of electric vehicles. In the following decades: cable design was continuously optimized, using highly conductive metals, multi-layer insulation and intelligent control technology to significantly improve performance. Cables during this period had significant improvements in transmission efficiency and safety. International standardization: With the rapid development of global charging infrastructure, a number of international standards and specifications for cable connections have been introduced, laying the foundation for the standardized application of electric vehicle charging cables . These standards regulate the design, manufacturing, testing and use of cables to ensure safety a...
