High-voltage cables inside large commercial vehicles such as electric buses and heavy-duty trucks are the core of high-voltage power transmission, directly affecting driving safety, system efficiency, and operational costs. Selection should focus on three key aspects: international standards, specification compatibility, and quality certification. Below, we analyze the key selection factors with industry data and objective information, along with references to high-quality products.

I. ISO 19642: The Core International Standard for Commercial Vehicle High-Voltage Cables

ISO 19642 is the core international standard for high-voltage cables in road vehicles. It is compatible with the high-voltage systems of new energy commercial vehicles (600V AC/900V DC, 1000V AC/1500V DC), covering all performance requirements for conductors, insulation, and flame retardancy, and meeting the access requirements for commercial vehicles in the international market. Core indicators: Operating temperature ranges from -40℃ to +150℃, flame retardant grade achieves self-extinguishing within 30 seconds, and conductors are made of multi-strand stranded oxygen-free copper to ensure low loss and high flexibility.

II. Data-Driven Compatibility of Core Specifications (150-240mm²)

Electric commercial vehicles are mainly compatible with cables with cross-sections of 150, 185, 200, and 240mm², corresponding to motor power of 200~450kW. Key data is as follows:

Note: The larger the cross-section, the stronger the current-carrying capacity, the lower the loss, and the more suitable it is for high-power and long-distance working conditions.

III. Key Quality Criteria: Certification and Reliability

1. Authoritative Certification: TUV Energy Storage/Automotive Cable Certification and CE Certification are core thresholds, ensuring electrical safety and international compliance; supplementary certifications such as UL and CQC can enhance global adaptability.
2. Quality Control and Reliability: High-quality products must pass annual third-party factory audits and unannounced inspections to control quality throughout the entire process. Leading industry products can achieve zero faults and zero batch complaints for many years. For example, the OMG’ ISO 19642 series has been applied in more than 100,000 vehicles with no quality issues for 16 years.

IV. Selection Recommendations

Selection should first meet the ISO 19642 standard, accurately match the cross-section according to the motor power, and balance quality and cost. Compliant and high-quality products (such as OMG’ electric vehicle high-voltage cables) can reduce procurement costs by 10%~20% and improve operational cost-effectiveness.

Conclusion: The ISO 19642 standard, accurate specification matching, authoritative certification, and reliable quality control are the core of selecting high-voltage cables for commercial vehicles. By combining your own vehicle needs and comparing compliant products, you can achieve the optimal balance between safety and cost.

Every reliable electric vehicle cable contains the secret to core materials that are suited to high voltage and heavy loads, balancing safety, durability and efficient power transmission. Let’s break down the key materials

Sheath material

🔹Cross-linked Polyethylene (XLPE)

🌡️ High heat resistance | 🧪 Chemical resistance

Suitable for EV high-voltage systems, capable of carrying high currents, and commonly used in Battery Management Systems (BMS) and main power transmission lines.

🔹 Polyvinyl Chloride (PVC)

💰 Cost-effective | 🔒 Wear-resistant

Used for insulation and sheathing in low-voltage auxiliary cables, suitable for non-high-voltage areas within the vehicle, balancing cost and basic protection.

🔹 Polyurethane (PU)

💧 Fully waterproof | 🛡️ Resistance to mechanical damage

Designed for damp and harsh environments such as under the vehicle and in the battery compartment, extending cable service life and suitable for outdoor wiring applications.

🔹Thermoplastic Elastomer (TPE)

🧩 High elasticity | 🚫 Resistance to ageing and cracking

Suitable for areas subject to frequent bending, such as door cables and steering system cables, balancing flexibility with durability.

🔹Polytetrafluoroethylene (PTFE/Teflon)

🔥 Extreme temperature resistance | 💧 Moisture and corrosion resistance

Suitable for high-temperature areas near motors and batteries, withstanding temperatures from -200°C to 260°C, and withstanding extreme operating conditions.

Core Conductor Materials

🟠 Copper Conductor

⚡ High Electrical Conductivity | 🔄 Flexible and Easy to Route

Used for high-voltage power transmission and sensor wiring, balancing transmission efficiency with ease of installation.

🔵 Aluminium Conductor

⚖️ Lightweight | 💸 Cost-Effective

Preferred for electric vehicle battery circuits and high-voltage buses, reducing vehicle weight and extending range.

Specialised Materials for Electric Vehicles

🔸 Shielding Materials (Copper Wire/Aluminium Foil)

🛡️ Resistant to EMI/RFI Interference | 📡 Signal Purity

Ensures stable signals for ADAS systems, on-board radar and charging cables, preventing interference-related faults.

🔸 Thermoplastic Vulcanised Ester (TPV)

🌡️ High thermal stability | 🔧 Strong sealing properties

Used for cable seals and sheathing, suitable for the high-voltage environment of the battery compartment, preventing electrical leakage and water ingress.
