PVC insulation is type C and sheath PVC is type ST4.

The national standard for the production of these cables is ISIRI 607-4 with the characteristic code (607)10 , which is equivalent to the international standard IEC 60227-4.

The abbreviation codes H05VV-U and H05VV-R (HD Standards) are used to identify these sizes, which of course is equivalent to the NYM abbreviation code in accordance with DIN VDE standards.

The above cables are used in the construction industry, electronic equipment, fixed electrical installations.
