How to improve the durability of EV charging cable

In the electric vehicle (EV) industry, the performance of charging cables directly affects charging efficiency and safety of use. Zhejiang Shuangyang Group, with its outstanding capabilities in material selection, structural design and manufacturing processes, is committed to providing customers with high-quality EV charging cables to ensure their reliability and durability in various extreme environments.

Material selection and optimization
The durability of the charging cable depends primarily on the choice of material. Zhejiang Shuangyang Group strictly adheres to the principles of high standards and high quality in this link to ensure that all materials meet the stringent usage requirements.
In terms of conductor materials, we use high-purity oxygen-free copper, which has excellent conductivity and good mechanical strength, ensuring the stability and reliability of the cable under long-term high-load operation. Oxygen-free copper not only improves current conduction efficiency, but also significantly reduces heat generation and extends service life.
The choice of insulation and jacket materials is also critical. We use cross-linked polyethylene (XLPE) and thermoplastic elastomer (TPE) as insulation materials. These materials not only have excellent electrical insulation properties, but also show good weather resistance, oil resistance and wear resistance, effectively resisting the external environment. of erosion. The sheath layer is made of high-performance polyvinyl chloride (PVC) or thermoplastic polyurethane (TPU), which further improves the durability of the cable and ensures its reliable operation in various complex environments.

Structural design and strengthening
Structural design is one of the key factors affecting the durability of EV charging cables. Zhejiang Shuangyang Group has significantly improved the cable's resistance to tearing, abrasion and aging through refined structural design.
The application of multi-layer shielding design effectively isolates electromagnetic interference and enhances the mechanical strength of the cable, ensuring that it maintains excellent performance in complex environments. Through the design of the shielding layer, the cable can reduce signal interference under high voltage and high frequency working conditions, ensuring the stability of the charging process.
In the design of the reinforced sheath, we specially added reinforcing ribs and braided mesh to improve the cable's tear and abrasion resistance. The thickness and material of the sheath layer have been carefully selected to ensure that it can resist external physical impact and chemical corrosion, thus extending the service life of the product.
Flexible bending design Considering the frequent bending and pulling of EV charging cables during use, we have optimized the bending radius and flexibility of the cables. Cables designed in this way can maintain good performance after long-term use and effectively reduce damage caused by frequent bending.

Manufacturing process and quality control
Manufacturing process and quality control are another important aspect that affects the durability of EV charging cables. Zhejiang Shuangyang Group adopts advanced manufacturing technology and strict quality control system to ensure that every cable meets the highest quality standards.
In terms of production equipment, we have introduced advanced production equipment from home and abroad, such as extruders, braiding machines, injection molding machines, etc., to ensure that the cable production process is accurate and efficient. The efficient operation of these equipment not only improves production efficiency, but also ensures product consistency and stability.
Strict quality control measures are implemented throughout the entire manufacturing process, including raw material inspection, production process monitoring and finished product testing, to ensure that every detail of the cable meets the design requirements. We use a systematic quality management system to ensure that every cable shipped out of the factory can meet the high standards of our customers.
