Building wires.

Building wires have one or two layers of PVC insulation and a small cross-section, and are used for lighting circuits, socket-outlet circuits indoors, and wiring inside residential distribution boards and control panels. Unlike power cables, building wires have no sheath for mechanical protection, so they must run in conduit or trunking, must not be buried directly, and must not be run outdoors unprotected.

Select on three points: solid single-wire or flexible multi-strand conductor (flexible conductors are easier to pull through conduit and withstand vibration better), cross-sectional area according to the load current, and the number of insulation layers. Hoang Nhat stocks Cadisun and Cadivi wires; both manufacturers publish the DC resistance for each cross-section, so it can be checked when calculating voltage drop on long runs.
