BVVB hard sheathed wire is a commonly used hard wire in home decoration. Its core is a solid single stranded copper wire, and the outer layer is protected by a sturdy sheath, making it less likely to deform or shift after wiring.
When decorating, bury it in the wall or lay it under the floor. It can maintain a fixed shape and will not cause line displacement over time. It is more suitable for long-term burial in dark wires than soft wires. Many households prioritize BVVB hard sheathed wires for lighting and ordinary socket wiring, as they have stable conductivity and slow oxidation rate after long-term use.
When wiring, be careful not to bend the BVVB hard sheathed wire. After bending the hard wire, the core inside is easily broken, and poor contact may occur during subsequent use. When threading the conduit, slowly follow the direction of the conduit and do not forcefully insert or pull it, otherwise it is easy to get the cable clip halfway.
As long as the wiring is done according to the specifications, this type of hard sheathed wire can work stably buried in the wall for more than ten years and rarely malfunctions.
