U758 Automotive High Voltage Cable Standard

China [CN]

Title ：Flame Retardant Performance Guarantee Mechanism for U758 Automotive High Voltage Cable Standard Application Specification 

Introduction: The flame retardant performance guarantee of the U758 automotive high-voltage cable standard application specification mainly depends on the selection and processing of cable materials, structural design optimization, and strict testing and certification. The specific analysis is as follows:

Cable material selection and processing

Selection of high flame retardant materials: The UL758 standard requires that the insulation and sheath layers of the cable use highly flame retardant materials, such as cross-linked polyethylene (XLPE), silicone rubber, etc. These materials can reduce the risk of fire spread under high temperature or fire conditions.

Application of halogen-free flame retardant technology: In the production of modern high-voltage cables, the use of halogen-free flame retardant technology is an important means to improve flame retardant performance. Halogen-free flame retardant materials release less toxic smoke and corrosive gases when burning, which is safer and more environmentally friendly.

Structural design optimization

Increase of shielding layer: In order to improve the overall safety of the cable, especially to enhance flame retardancy while preventing electromagnetic interference, UL758 standard cables are often equipped with shielding layers. This shielding layer not only helps to improve the electromagnetic compatibility of the cable, but also can block flames to a certain extent and slow down the spread of fire.

Double-layer structure design: In some application scenarios with special requirements, the use of a double-layer sheath design can greatly enhance the flame retardant performance of the cable. The inner sheath is responsible for basic insulation protection, while the outer sheath uses materials with better flame retardant properties, forming a double guarantee.

E-MARK and other certifications: By obtaining internationally recognized third-party certifications such as E-MARK, it is proved that the cable products meet strict international safety standards, including excellent flame retardant properties.

Strict control of production process

Advanced preparation process: The use of advanced manufacturing technology and equipment, such as catenary dry cross-linking (CCV) and vertical dry cross-linking (VCV), ensures that each production link of the cable reaches the best quality, thereby ensuring the flame retardant properties of the final product.

In summary, the flame retardant properties of automotive high-voltage cables under the U758 standard are guaranteed by high-standard material selection and processing, scientific design optimization, strict testing and certification, and precise production processes. These measures work together to ensure that the application of cables in electric vehicles is both safe and reliable.
