UL2263 automotive high-voltage shielded cable for new energy vehicles

Introduction: UL2263 is a standard for electric vehicle cables, which specifies the performance requirements, test methods, etc. of electric vehicle cables in detail. Regarding UL2263 automotive high-voltage shielded cable, we can introduce it from the following aspects:

1. Standard Overview

Standard Name: UL2263 Standard for Electric Vehicle Cable (Electric Vehicle Cable Standard)

Release Time: First Edition Released on May 9, 2022

Scope of Application: This standard replaces the part of the UL62 standard on electric vehicle cables and is specifically used for the certification and testing of electric vehicle cables.

2. Cable Types and Specifications

Under the UL2263 standard, there are mainly several types of high-voltage shielded cables for electric vehicles. According to the different insulation materials, they can be divided into three types: thermosetting material insulation, thermoplastic elastomer insulation and thermoplastic insulation. Each type has different voltage levels and temperature levels to meet different application requirements.

3. Characteristics of high-voltage shielded cables

High-voltage performance: These cables are designed for high-voltage environments and can withstand voltages up to 1000V AC or DC to ensure the safety of electric vehicle charging and power transmission.

Shielding layer design: The cable adopts a shielding layer design, which can effectively reduce electromagnetic interference (EMI) and radio frequency interference (RFI), and improve the accuracy and stability of signal transmission.

Insulation and sheath materials: The selection of insulation and sheath materials strictly follows the UL2263 standard, and has good oil resistance, acid and alkali resistance, water resistance, wear resistance, tensile resistance, rolling resistance, crack resistance and UV resistance, ensuring the reliability and durability of the cable in various harsh environments.

Conductor material: The conductor is mainly made of soft copper or electroplated soft copper, with good conductivity and mechanical strength, ensuring the efficiency and stability of current transmission.

IV. Application scenarios

UL2263 automotive high-voltage shielded cables are widely used in electric vehicle charging stations, parking lots, hotels, communities, garages and other areas, as well as portable charging cables. They connect electric vehicle charging devices with charging infrastructure to achieve safe and efficient transmission of electricity.

4. Testing and certification

In order to ensure that the cable meets the requirements of the UL2263 standard, manufacturers need to conduct a series of rigorous tests and certifications. These tests include permittivity test, stability factor test, insulation resistance test, withstand voltage test, etc. to ensure that the electrical performance, mechanical performance and environmental resistance of the cable meet the standards.

5 Summary

UL2263 automotive high-voltage shielded cable is a high-voltage cable designed for electric vehicles with excellent electrical performance, mechanical performance and environmental resistance. They pass rigorous testing and certification to ensure safety and reliability during electric vehicle charging and power transmission. With the continuous expansion of the electric vehicle market and the continuous advancement of technology, the application prospects of these cables will be broader.
