Notes：
Voltage Class: 450/750 V means the cable is suitable for low voltage power systems, U₀ is conductor-to-ground voltage, and U is inter-conductor voltage.
Cross-Sectional Area: The common specifications are 1.5 mm² ~ 400 mm², the specific selection depends on the load current and the installation environment.
Temperature Range: Regular operating temperature is -30°C ~ +70°C, suitable for most indoor environments.
Voltage Withstand Test: 2000 V AC test ensures the insulation performance of the cable under high voltage.
Security and Certification
Certification Standards: HD 21, IEC 60227, EN 50525.
Installation Recommendations: Avoid overstretching, use wireway/casing protection, and ensure reliable grounding.
Environmental Protection: RoHS compliant, Low Smoke Zero Halogen (LSZH) version available on some models.
The difference between the H07V-K cable and the H05V-K model is that the H05V-K is rated at 300/500V for lower power scenarios. Regarding the color selection of the cable, the H07V-K cable’s multiple color markings are used to differentiate between the lines in the distribution line and do not affect its electrical properties, etc.
