Oil-cooled charging cable breaks through power bottleneck and defines super charging

China [CN]

For high-power scenarios such as 800V + high-voltage platform, 4C/5C super-fast charging, etc., cable manufacturers' oil-cooled charging cables use liquid cooling technology and high-strength structural design to solve the problems of high heat generation, insufficient temperature resistance, and mechanical stress sensitivity of traditional charging cables, becoming the core preferred solution for car companies and charging equipment manufacturers. ​Among them, OMG focuses on cable research and development, production and manufacturing.

Introduction to the performance technology of oil-cooled charging cables:

1: Oil-cooled circulation heat dissipation, charging efficiency can be increased by 30%​

Innovative built-in spiral oil cooling channel, using low-viscosity thermal oil (specific heat capacity ≥2.5kJ/kg・K) to achieve active heat dissipation, combined with the outer layer of high thermal conductivity aluminum alloy sheath, the conductor temperature can be controlled within 75℃ (conventional cable temperature rise exceeds 100℃), supporting 600A-1200A continuous high current transmission without attenuation, 400km endurance replenishment takes only 10 minutes, perfectly adapted to super charging piles, heavy truck fast charging and other scenarios.​

Two: Wide temperature, weather resistance and mechanical shock resistance, stable operation under all working conditions​

The conductor is made of 99.99% high-purity oxygen-free copper (tin-plated anti-oxidation treatment), the insulation layer is 150℃ resistant cross-linked polyethylene, and the sheath is made of tear-resistant TPU material, which supports **-40℃~150℃ wide temperature operation**, and has passed the IP68 protection level test (immersed in 1 meter underwater for 24 hours without water ingress). The cable has a built-in aramid fiber tensile layer (breaking strength ≥300N/mm²), the minimum bending radius is only 6D, and the number of bending resistance exceeds 200,000 times, which can easily cope with the mechanical stress scenarios of frequent plugging and unplugging and dragging of charging guns. ​

Three: Fully compatible design and authoritative certification, adapted to global supercharging standards​

Supports mainstream interface protocols such as CCS1/CCS2/GB/T 20234.3, the outer diameter of the cable is 15% smaller than that of the same specification liquid cooling cable, and the lightweight design is easier to integrate into the charging gun. It has passed 10 international certifications including UL 62, TÜV Rheinland, CQC, etc., complies with RoHS 3.0 environmental protection directive, and can be used in multiple scenarios.
