When selecting cables for power distribution, control panels, industrial equipment or automation systems, many engineers and buyers often confuse H07V-K and H07G-K. At first glance, both are flexible copper conductor wires, but their insulation materials, temperature ratings, flexibility, and application environments differ significantly. Choosing the wrong type may lead to insulation aging, cable hardening, or even electrical risks, resulting in reduced system reliability and increased maintenance costs. Understanding the differences between H07V-K and H07G-K will help ensure safety, performance stability, and overall cost efficiency in your project.
H07V-K vs H07G-K – Basic Definitions and Standards
Both H07V-K and H07G-K are single-core flexible copper cables, but they comply with different insulation materials and standards.
- H07V-K is a PVC-insulated flexible wire designed for fixed installations inside electrical cabinets, control panels, and conduits.
- H07G-K is a EVA (Ethylene Vinyl Acetate) cable built to withstand extreme heat, commonly used in industrial and high-temperature applications.
Below is a clear comparison of their technical characteristics:
| Item | H07V-K | H07G-K |
|---|---|---|
| Conductor | Class 5 flexible copper strands | Class 5 flexible copper strands |
| Insulation Material | PVC (Polyvinyl Chloride) | EVA (Ethylene Vinyl Acetate) |
| Rated Voltage | 450/750V | 450/750V |
| Continuous Operating Temperature | Up to 70°C | Up to 110°C |
| Flexibility | High | Very high (better fatigue resistance) |
| Standard Reference | IEC 60227 / EN 50525-2-31 | IEC 60245 / EN 50525-2-41 |
| Cost Level | Cost-effective | Medium / higher |
Performance Comparison: Key Differences That Matter
Temperature Resistance
The most notable difference lies in thermal endurance.
- H07V-K operates safely up to 70°C, making it ideal for standard electrical environments.
- H07G-K, insulated with EVA, maintains stability and flexibility at temperatures up to 110°C, ideal for equipment with heat sources.
Mechanical & Chemical Durability
- H07V-K provides stable mechanical strength and is cost-effective for everyday installations.
- H07G-K offers superior resistance to oils, ozone, and UV exposure, perfect for demanding industrial settings.
Flexibility
Both cables are highly flexible, but H07G-K maintains flexibility even under heat, cold, or vibration - a crucial factor for moving machinery and robotic systems.
Cost and Performance Balance
H07V-K is more economical for standard indoor wiring, while H07G-K delivers long-term reliability where temperature and durability are critical - providing better total cost efficiency over time.
Application Scenarios: Choosing the Right Cable for Your Needs
H07V-K Applications
- Electrical control panels
- Switchboards and distribution boxes
- Fixed wiring inside conduit systems
- Building and residential installations
Why choose it: Ideal for cost-effective, standard installations requiring flexibility and safety under moderate temperatures.
H07G-K Applications
- Industrial ovens, furnaces, and heating systems
- Steel plants, glass production lines, and chemical processing

- Robotics and automation equipment
Why choose it: Designed for harsh environments, continuous movement, and extreme heat resistance.
Cable Selection Guide
When choosing between H07V-K and H07G-K, consider the following key factors:
| Selection Criteria | Recommended Cable |
|---|---|
| Working temperature below 70°C | H07V-K |
| High-temperature environments (up to 110°C) | H07G-K |
| Fixed installation | H07V-K |
| Moving or vibrating applications | H07G-K |
| Budget-friendly solution | H07V-K |
| Long-term durability & heat resistance | H07G-K |
