If you’re sourcing electrical cables for international projects, you’ve probably run into the same problem many buyers face: each country uses different cable names and standards, and it’s hard to know which type is correct for Australia, China, or Southeast Asia. Choosing the wrong cable can delay your project, fail inspection, or even create safety risks.
This guide gives you a simple, high-level explanation of the most common global cable types and a quick comparison of regional naming systems, so you can understand the differences in just a few minutes.
With more than 40 years of manufacturing experience and cable projects delivered to over 30+ countries, NAN CABLE has helped thousands of contractors, distributors, and engineering teams select the right cables for their markets. We know exactly where international buyers get confused—and how to simplify the decision.
Let’s look at the key cable types and how standards differ across regions, so you can choose the right cable with confidence.

Overview of Global Electrical Cable Types
Electrical cables used worldwide can be grouped into two major categories based on their core function: power transmission and signal or data communication. This distinction helps you quickly choose the right cable for powering a building or transmitting high-speed data across a network. Here’s a simplified overview of global cable types for a clear and easy understanding.
- Power & Electrical Distribution Cables (Energy Transmission)
(Used for power supply, infrastructure, industrial systems, utilities)
| Cable Type | Voltage Range / Purpose | Common Applications |
|---|---|---|
| Low Voltage (LV) Cables | 50–1000V AC / 75–1500V DC | Homes, small buildings, lighting, appliances |
| Medium Voltage (MV) Cables | 1–33 kV | Industrial plants, commercial buildings, local distribution networks |
| High Voltage (HV) Cables | 66–132 kV | Utility transmission, substations |
| Extra-High Voltage (EHV) Cables | 275 kV and above | Long-distance power transmission |
| Armoured Cables | Mechanical protection for 0.6/1kV–MV systems | Underground installation, outdoor feeders, harsh environments |
| Flexible Power Cables | Flexible copper conductors for movable use | Machinery, robotics, appliances, automation systems |
| Submarine Power Cables | Underwater HV/EHV transmission | Offshore wind farms, island grids, subsea interconnections |
- Communication, Data & Control Cables (Signal Transmission)
(Used for power supply, infrastructure, industrial systems, utilities)
| Cable Type | Purpose | Common Applications |
|---|---|---|
| Coaxial Cable | High-frequency signal transmission | TV systems, broadcasting, internet modems |
| Twisted Pair (UTP/STP) | Network & voice communication | Ethernet networks, telephone lines |
| Fiber Optic Cable | Long-distance, high-speed data via light | Internet backbone, telecom, data centers |
| Control & Instrumentation Cables | Low-voltage control signals | Automation systems, process control, sensors |
Short Comparison of Regions (Australia / China / Southeast Asia)
Australia
In Australia, cables are named according to AS/NZS standards, such as V90 or NYY. The codes indicate insulation type, voltage rating, and fire performance. Australian standards focus on UV resistance, high temperatures, and outdoor durability, which is why U.S.-style cables like THHN are rarely used there.
China Mainland
China uses the GB/CCC standard system, with cables like YJV and YJV22. The letters represent the insulation and sheath materials (e.g., YJ = XLPE, V = PVC), and additional numbers indicate armouring or fire resistance. These standards emphasize industrial applications and large infrastructure projects, differing from U.S. and Australian codes.
Southeast Asia (Thailand, Malaysia, Indonesia, etc.)
In Southeast Asia, cables often follow IEC standards, combined with local rules. Common types include NYM and CV, suitable for humid climates and corrosion-prone environments. SEA naming reflects voltage rating, insulation, and flexibility, catering to diverse applications from building wiring to industrial machinery.
Quick Cable Selection Tips
Choosing the right electrical cable for international projects involves considering key factors to ensure safety and compliance:
- Application
Select cables based on the load they’ll carry. For light loads (e.g., lighting), use smaller gauges (1.5mm² or 16 AWG). For heavier appliances (e.g., air conditioners), choose larger cables (e.g., 10mm² or 8 AWG).
- Voltage Rating
Ensure the cable's voltage rating matches the system’s requirements. For instance, North American systems use 120V and 240V, while Europe uses 230V.
- Ampacity
Choose a cable with an ampacity that exceeds the maximum current expected. Undersized cables can overheat and pose a fire risk.
- Location
Consider the environment where the cable will be installed. Use moisture-resistant cables like UF for underground projects and durable BX cables for exposed indoor areas.
- Code Compliance
Adhere to local electrical codes. Cable types like V90 (Australia), NYM (China), and CV (China) have regional specifications to meet.
The table below presents the corresponding parameters between the American Wire Gauge (AWG) and the European metric system (mm²), along with their current consumption and common application scenarios.
| Nominal Cross-Section Area (mm²) | AWG | Current Consumption | Application |
|---|---|---|---|
| 1.5 | 16 | Low | Low Lighting, small appliances |
| 2.5 | 14 | Under | General power circuits |
| 4 | 12 | Medium | Kitchen appliances |
| 6 | 10 | Medium | Electric heaters |
| 10 | 8 | Medium High | Outdoor outlets |
| 25 | 4 | Very High | Solar power, industrial equipment |
