PVC Wiring Cable / PVC-Insulated Single Core

PVC Wiring Cable / PVC-Insulated Single Core

Application:

Installation in electrical installation conduits, either surface-mounted or flush-mounted, or in similarly enclosed systems. Any use other than the recommended one may lead to a reduction in safety and/or a decrease in the expected service life of the cable. Use outside the described and specified application is not intended.

Temperature Range:

• Static condition: -40°C / +70°C
• Flexing condition: +5°C / +70°C

Cross-Section Range:

• H05V-K: commonly used for cross-sections up to 1 mm²
• H07V-K: typically starts from 1.5 mm² and above

This means:

• A cable with 0.5 mm² or 1 mm² is usually designated as H05V-K.
• From 1.5 mm² upward, it is classified as H07V-K, even if the construction is similar.

Why is that?  The difference lies in the rated voltage and insulation thickness:

• H05V-K: Rated voltage 300/500 V
• H07V-K: Rated voltage 450/750 V

The higher voltage rating of H07V-K requires thicker insulation, which also results in a larger outer diameter. This thicker insulation is only economically and technically reasonable from a certain conductor cross-section upward.

Technical Background:

The designation “05” or “07” in the type code indicates the voltage rating:

• “05” → 300 V between conductor and earth / 500 V between conductors
• “07” → 450 V between conductor and earth / 750 V between conductors

Note: The choice between H05V-K and H07V-K depends not only on the cross-section but also on the required voltage resistance and the installation environment. In safety-relevant areas or applications with higher voltages, H07V-K is mandatory.
