How does VVG differ from PVC?

VVG is a power cable with rigid copper conductors for stationary wiring: it is laid in walls, grooves, and trays. PVC is a flexible wire made of stranded conductors, designed for carrying and bending, therefore used for extension cords and connecting household appliances, not for concealed wiring.

Where is NYM used?

NYM is a power cable according to the German standard with an additional chalk sheath under the insulation. It is used for wiring in apartments and houses when neat installation and convenient termination are required. In terms of purpose, it is similar to VVGng, but differs in the sheath construction.

Can SHVVP cable be used for sockets?

PVC-insulated wire for low-power devices, lamps, and extension cords with low current. Not suitable for wiring outlets: the cross-section and insulation are not designed for continuous load. For outlets, use VVG 3×2.5.

What cable is needed for wiring in the apartment?

The standard choice is copper VVG (or VVGng-LS, which is less flammable and smoky): 3x2.5 for sockets and 3x1.5 for lighting. Powerful equipment is powered by separate lines of appropriate cross-section.

What to take for an extension cord or connecting equipment?

Flexible PVC wire of the required cross-section: 3×1.5 or 3×2.5 depending on the power of the device. It does not break when bent, unlike rigid VVG.
