Details of standard requirements for insulation materials of new energy cables

With the rapid development of the new energy industry, new energy cables, as key components of power transmission, have increasingly stringent standard requirements for insulation materials. The following is a detailed analysis of the standard requirements for insulation materials of new energy cables:

1. Physical performance requirements

The physical properties of insulation materials of new energy cables must comply with national standards, mainly including:

Tensile strength: ensure that the cable is not easy to break when stretched by external force, and ensure the stability and safety of the cable.

Elongation at break: reflects the elongation ability of the material before breaking, and is an important indicator for evaluating the flexibility of the material.

Hardness: Appropriate hardness can not only ensure the insulation performance of the cable, but also avoid excessive wear during installation and use.

2. Electrical performance requirements

Electrical performance is the core requirement of insulation materials of new energy cables, mainly including:

Dielectric strength: indicates the ability of the material to withstand the action of the electric field without being broken down, and is a key indicator for evaluating the insulation performance of the cable.

Volume resistivity: reflects the difficulty of charge transfer inside the material. High volume resistivity means that the material has good insulation performance.

Dielectric loss: Under the action of the electric field, part of the electrical energy in the insulating material will be converted into heat or other forms of energy and lost. The smaller the dielectric loss, the higher the transmission efficiency of the cable.

3. Heat resistance requirements

New energy cables may be subjected to higher temperatures during operation, so the heat resistance of the insulating material is crucial. Mainly include:

Long-term use temperature: refers to the maximum temperature that the cable can continuously withstand under normal working conditions. The insulating materials of new energy cables are usually required to have a higher long-term use temperature to meet the needs of different application scenarios.

Short-term overload temperature: In a short period of time, the cable may be subjected to high temperatures exceeding the normal working temperature. The insulating material needs to have a good short-term overload temperature tolerance to ensure the safe operation of the cable.

In summary, the standard requirements for new energy cable insulation materials cover physical properties, electrical properties, heat resistance, environmental aging resistance and other aspects to ensure that the cable can maintain stable insulation performance and good operating conditions in various application scenarios.

At present, in most cable companies, technicians have professional product knowledge to shine in various positions and bring new products and technologies to future customers.

Among them, the work order of cable manufacturers' technicians is an important link to ensure production quality, efficiency and safety. An efficient and orderly work system for technicians can significantly enhance the competitiveness and market position of enterprises. Here are some suggestions to promote the work order of cable manufacturers' technicians:

1. Clarify job responsibilities and task allocation:

Clearly define the job responsibilities of each technician, including design, research and development, production guidance, quality control, equipment maintenance, etc.

Make reasonable task allocation according to project requirements and technician expertise to ensure effective use of resources.

2. Establish standardized operating procedures:

Develop and continuously improve standard operating procedures (SOPs) for various links such as cable production, testing, and maintenance.

Emphasis that technicians must strictly abide by SOPs to ensure product quality and production safety.

3. Regularly organize technicians to participate in professional skills training, new product technology seminars, etc. to improve the overall technical level of the team.

Encourage technicians to learn independently, share and exchange experiences, and form a good learning atmosphere.

4. Implement effective communication and collaboration mechanisms:

Establish cross-departmental communication channels to ensure smooth information flow between technical personnel and production, sales, procurement and other departments.

Emphasis teamwork, and jointly solve technical problems in production through regular meetings, project discussions, etc.

5. Optimize work processes and improve efficiency:

Analyze bottlenecks in the production process and improve them through technological innovation, equipment upgrades, etc.

6. Introduce advanced production management systems to achieve digital and intelligent management of the production process and improve production efficiency.

Through the implementation of the above measures, cable manufacturers can establish an efficient and orderly work order for technical personnel, providing strong guarantees for the sustainable and healthy development of the company.

New energy vehicle wiring harnesses are responsible for transmitting signals and electrical energy, providing power supply for various electrical equipment, and ensuring the coordination of various parts of the vehicle is also one of its important responsibilities. The production and installation of high-voltage wiring harnesses directly affect the performance, efficiency and reliability of new energy vehicles.

New energy electric vehicles require a more powerful, fast and efficient power supply system. There are a large number of wiring harnesses arranged inside electric vehicles to transmit control signals and electrical energy, supply power to electrical equipment, and are an important "central nervous system" of the vehicle. In order to ensure stable power supply to devices inside and outside the vehicle, the automotive wiring harness connection must be zero-fault and strong enough.

Electric vehicles rely on strong electrical connections to effectively distribute battery power, which involves wiring harness routing issues. Issues that need to be considered in wiring harness layout include thermal management, contact resistance, connector size, mechanical stress load, etc., and the wiring harness welding shaping process can effectively solve the above problems.

The high-voltage wiring harness welding shaping process is to compact the loose multi-strand wiring harness and weld it into the required shape to facilitate connection with other components.

As the contact resistance increases, the current will decrease, a lot of heat will be generated on the contact surface, and over time, excessive temperature will shorten the service life of the wiring harness. High-voltage wire harness connectors treated with welding shaping process will reduce contact resistance and reduce the heat generated by the electrical system, thereby extending service life.

Wire harness welding shaping process is an ideal solution for copper wire welding, ensuring reliable connection while increasing product life. High-voltage welding wire harness makes the connection safer and more reliable, and can effectively reduce problems caused by mechanical stress load.
