Description of APUNP wire

APUNP is a flat aluminium household wire for concealed installation in the walls of residential buildings under plaster. It is used in lighting and low-current power networks. It is intended for electrical networks protected against current overloads and short circuits by circuit breakers. Rated voltage up to 250 V at 50 Hz.

The aluminium conductors make the wire cheaper than its copper counterpart PUNP, but they require care during connection: Al-Cu connectors are needed for joining to copper terminals in order to prevent electrochemical corrosion. Current building regulations (SNiP) restrict the use of aluminium wiring in residential construction – PUNP or PuV installation wires are recommended.

Applications

Fixed installation in the walls of residential buildings under plaster

Lighting networks of residential, domestic and utility premises
