Application Standards for Charging Cables for Heavy-Duty Transport Vehicles

China [CN]

Description: Charging cables for heavy-duty transport vehicles must strictly adhere to three core standards: National Standard GB/T 33594-2017, CQC1103-2014 Technical Specifications, and the Megawatt-level Charging Special Standard. The standards specify that the cable's rated voltage should not exceed 1500V DC, and the maximum rated current can cover 3000A, meeting the high-efficiency power replenishment needs of large equipment such as heavy trucks and electric ships. Technically, the insulation material must possess excellent voltage resistance and thermal stability; the sheath must pass ozone resistance, crack resistance, and 100℃×168h oil resistance tests; and the mechanical strength must meet the compressive stress ≥11kN. The standard also stipulates that cables must have comprehensive thermal management and electromagnetic compatibility design, be crack-free when bent at low temperatures, and have a protection level suitable for harsh outdoor environments. It also ensures interoperability between equipment from different manufacturers, filling a gap in industry standards. Of course, the specific requirements may vary depending on the actual application scenario and product specifications.
