With the development of the automotive technology era, it has become a convenient way of travel in our lives. Charging piles used to supplement power for new energy electric vehicles have also become a normal part of life. Whether in companies, communities or other public places, you can see charging piles in operation.
As a bridge connecting the pile and the car, the performance of the charging pile cable is crucial. So, what are the characteristics of the charging cable in terms of materials The following is a brief overview:
In addition to the basic cable outdoor performance such as insulation and flame retardancy, the overall hardness of the cable should not be too high because it needs to be bent frequently. The so-called charging pile cable material actually generally refers to elastomer-related materials, which are used for the insulation layer and sheath layer. The material performance requires oil resistance, tear resistance, weather resistance, chemical resistance, high and low temperature resistance and softness. At present, the more mainstream ones are TPU, TPE, PVC elastomers, etc. The following briefly introduces the characteristics and differences between TPU and TPE.
Among them, most of the insulation protection materials for automotive wiring harnesses with a temperature level of 105℃ and below are PVC materials. Domestic automotive wiring harnesses often have disadvantages such as poor extrusion surface and poor low temperature performance. In view of this, coupled with the special environment (such as small space, poor environmental heat dissipation, frequent mutual friction, etc.) and special requirements (thin wall, high-speed extrusion, etc.) and cost control requirements of automotive wiring harnesses, it is necessary to study PVC materials used in automotive wiring harnesses and further improve their performance.
With the continuous enhancement of people's environmental awareness, relevant environmental regulations such as the EU RoSH standard and REACH regulations have been gradually implemented in the electronic and electrical fields. In many occasions, thermoplastic flame-retardant safe and clean wires and cables must be used, and TPE halogen-free flame-retardant cable materials with both plastic and rubber properties have become the focus of research and development.
Here, we thank every participant for their enthusiastic viewing and active participation, and hope that everyone can continue to maintain their enthusiasm and jointly explore the challenges and opportunities in the field of electric vehicle cables. Welcome to search: OMG EV cables
