Performance introduction of motor vehicle application cables

China [CN]

Product introduction: Introduces the use requirements, structural analysis, technical characteristics, manufacturing process, test project difference comparison of 30kV single-phase power cables for vehicles. The actual service life of the product remains to be verified, and the research and development of cable accessories needs to be further increased.

Usage requirements: 30kV single-phase power cables for locomotives are mainly used to connect pantographs, main circuit breakers, traction transformers and other high-voltage equipment inside and outside locomotives to transmit power for locomotive electric traction devices. The cable should be environmentally friendly, safe, oil-resistant, acid- and alkali-resistant, ozone-resistant, moisture-resistant, sunlight-resistant, impact-resistant, and high-temperature-resistant in harsh environments.

The current product is produced in accordance with TB/T 1484.2-2017 "Road Vehicle Cable Part 2: 30kV Single-Phase Power Cable". The insulation thickness of the product is relatively thin, and the shielding is shielded by metal wire bundles, which can meet the application requirements of high-speed trains such as high-speed rail and EMUs and ordinary trains.

Structural analysis: For example, based on the 95mm² cable sample, the technical characteristics of the cable can be roughly referred to the following series: https://www.omgevcable.com/ev-cables/414.html
