With the rapid development of new energy vehicles, the global charging pile market is experiencing growth. As one of the core components of the charging pile system, the quality of the cable directly affects charging safety, service life and user experience. In the selection of cable sheath and insulation layer materials, TPU material (thermoplastic polyurethane elastomer) has become the first choice for many charging pile cable manufacturers due to its excellent mechanical properties, environmental protection characteristics and excellent weather resistance.
So why is TPU Material the preferred material for charging pile cable sheath and insulation at present?
AngreenTPU Sheath/Insulation Material can Provide a Full Range of Solutions for Charging Pile Cable.
Charging pile cables need to withstand high voltage and high current transmission, and are often exposed to outdoor environments, exposed to the sun and rain, alternating between cold and heat, and may even be damaged by external forces.
Therefore, the charging pile cable sheath and insulation layer must have the following characteristics: strong weather resistance, wear resistance and tensile resistance, high flame retardancy, oil resistance and chemical corrosion resistance, environmental protection and non-toxicity, and good flexibility. Therefore, this requires that the materials used to manufacture charging pile cables must meet the above conditions.
Charging pile cables are often pulled, stepped on, or even bent, especially in public charging stations and commercial charging scenarios, and ordinary materials are prone to wear and breakage. The wear resistance of TPU is 3-5 times higher than that of PVC, and the tear resistance is far higher than that of traditional rubber, which can effectively prevent the outer skin from being damaged.
In cold areas, ordinary rubber materials will become brittle, harden, and crack easily in low-temperature environments. TPU still maintains its flexibility at a low temperature of 40°C, ensuring that the cable is still easy to operate in extreme weather without affecting charging efficiency.
Charging pile cables are usually exposed to sunlight, rain, and humid environments for a long time. TPU has excellent UV and ozone resistance, and can maintain stable performance even in harsh environments, extending service life.
Electric vehicles require high power transmission when charging, and cables may cause high temperatures or even fires under conditions such as overload and short circuit. Therefore, the cable sheath material must have excellent flame retardancy. TPU can easily reach the UL94 V-0 flame retardant rating. Compared with PVC and rubber, TPU does not release toxic gases when burning, and meets more stringent environmental protection and safety standards.
In commercial charging stations, cables may be exposed to oil, lubricants or other chemicals. PVC and rubber are prone to aging after long-term contact with these substances. TPU has excellent oil resistance and chemical corrosion resistance, and maintains stable performance even in harsh environments, reducing maintenance costs.
With the tightening of global environmental regulations (such as EU RoHS, REACH, etc.), many countries have banned the use of lead and halogen-containing cable materials. TPU does not contain harmful substances and is recyclable, which is in line with the trend of sustainable development and helps companies meet environmental regulations.
At present, many charging pile brands around the world have begun to adopt TPU cable sheaths, and the market feedback is good.
For example:
Tesla's super charging piles partially use TPU cables, which improves the durability and safety of charging cables.
International power equipment manufacturers such as ABB and Schneider also use TPU cables in high-end charging pile products to improve the overall performance and market competitiveness of the equipment.
Domestic brands Weilai, Xiaopeng, and BYD are also gradually promoting TPU sheathed cables to enhance user experience and brand image.
On the whole, TPU materials have incomparable advantages in the application of charging pile cable sheaths and insulation layers. It not only improves the durability and safety of cables, but also complies with environmental regulations and adapts to the development trend of the future new energy industry. If you are looking for a high-performance, environmentally friendly and safe cable material, TPU is undoubtedly the best choice.
With the continued growth of the new energy vehicle industry, the market penetration rate of TPU cable sheaths will further increase, and may even become the standard configuration of the charging pile cable industry in the future.
