| Brands of wires | Name of wires and their elements | The predominant usage |
| PV1 | Installation wire with copper strand (single-wire), with polyvinyl chloride isolation | For not flexible installation of electrical circuits |
| PV2 | Installation wire with copper strand (multi-wire), with polyvinyl chloride isolation, flexible | For installation of electric circuits on sites where bends of wires are possible |
| PV3 | Installation wire with copper strand (multi-wire), with polyvinylchloride isolation, with increased flexibility | For installation of electrical circuits in areas where frequent bending of wires during installation is possible. |
| PV1ng | Installation wire with copper strand (single-wire), with polyvinyl chloride isolation, with reduced flammability | For not flexible installation of electric circuits where the increased requirements to not spreading of burning are shown |
| PV2ng | Installation wire with copper strand (multi-wire), with polyvinyl chloride isolation of reduced flammability, flexible | Similar to PV1ng for areas where bending of wires is possible |
| PV3ng | Installation wire with copper strand (multi-wire), with polyvinyl chloride isolation of reduced flammability, with increased flexibility | Similar to PV2ng for areas where frequent bending of wires during installation is possible. |
