Cu + single-core
Household single-core copper wire
PUN is a single-core household wire with a copper conductor and PVC insulation, without a sheath. An equivalent of APUN, but with copper conductors. It is used for installation as individual insulated wires in protected ducts and for wiring inside junction boxes. Designation breakdown: PU – installation wire, N – fixed (stationary).

PUN is a single-core household copper wire without a sheath. It is used for installation as individual insulated wires in conduits, trunking and cable ducts, and for wiring in junction boxes and automation panels. Convenient for routing individually coloured cores along the designed routes.
Cross-sections of 0.75-1.5 mm² are for low-current circuits and lighting; 2.5 mm² for household socket outlets; 4-6 mm² for high-power loads and trunk lines inside distribution boards. Direct connection to copper terminals without adapters.
