h07v k and h05v k cables

What are H07V-K Cable and H05V-K Cable?

H07V-K and H05V-K cables are both examples of harmonized hook up wire. These flexible, single-conductor PVC hook up wires are built according to the standards set forth by CENELAC under Harmonization Document 21. HD 21 encompasses several European standards with a smaller scope. Harmonization means a recognized international organization develops a common standard to be used across Europe. You can learn more about harmonization here.


H07V-K and H05V-K cables are used in electronic and electrical equipment, specifically in devices designed for export to Europe. If you're using equipment made in Europe, a harmonized wire is the recommended MRO replacement. H07V-K and H05V-K wires are PVC hook up wire, so they get used in the internal wiring of appliances, apparatus, switchboards, distributor boards, and telecommunication devices.


Much like US mil-spec part numbers, you can tell a lot about the construction of a harmonized cable by breaking down its part number.

    • 07  -  450/750 Volt
  • Insulation
    • V  -  PVC
    • R  -  Rubber
    • S  -  Silicone Rubber
  • Sheath-Cladding Material
    • V  -  PVC
    • R  -  Rubber

    • J   -  Glass-filament Braiding
    • T  -  Textile Braiding
  • Number of Conductors
  • Special Features
    • H  - Ribbon Cable, Separable
    • H2  -  Ribbon Cable, Non-Separable
  • Protective Conductors
    • X  -  Without Protective Conductor
    • G  -  With Protective Conductor
  • Conductor Types
    • U  -  Single Wire

    • F  -  Fine Wire (Flexible)
    • H -  Super Fine Wire
    • Y  -  Tinsel Strand
  • Conductor Cross-Sectional
    • The area specified in mm²

Just from the part numbers, we know that both H07V-K and H05V-K have permanently installed fine wire conductors insulated with PVC. Where the two wires differ is in voltage. This is because H05V-K cable specs span from only 20 AWG to 17 AWG, whereas the H07V-K specs apply to 16 AWG and larger. H07V-K wire's larger gauge size permits a higher voltage rating.

Harmonized cables are identifiable by a mark either externally on the outer jacket or insulation, or internally with printed tape inside the cable. H05V-K and H07V-K cables are available in a variety of colors: black, green/yellow, brown, red, white, gray, violet, pink, orange, beige, blue (RAL5015), dark blue (RAL5010), marine blue (RAL5002). If you don’t need to meet the harmonized standard, this wire is also available in transparent, yellow, and green insulation.

H07RN-F Cable

Though it’s only a couple of letters off from H07V-K, the H07RN-F is a whole different product. H07RN-F cable is a harmonized portable cord under HD 22. Like H07V-K cable, it has a working voltage of 450/750 volts, but unlike the PVC hook up wire, H07RN-F cable has rubber insulation and a synthetic rubber jacket over flexible fine wire conductor(s).

H07RN-F portable cord is used in electrical equipment under medium mechanical stress in outdoor or indoor environments, dry or damp. H07RN-F is often used in boilers, heating plates, hand lamps, electric tools, transportable motors, or onsite machines. You can learn more about theH07RN-F cable specs here.

Having a basic understanding of the harmonized wire coding system will help you quickly identify cable types and know your hook up wires from your portable cords. If you have any unanswered questions about H05V-K and H07V-K hook up wire or H07RN-F portable cord, email them to [email protected].
