BVV and BVVB sheathed cables differ significantly in structure, appearance, purpose, and application scenarios.
Structure and Appearance:
BVV: This is a copper-core, PVC-insulated, PVC-sheathed round cable, consisting of a single core and two layers of sheath, with the appearance of a round wire.
BVVB: This is a copper-core, PVC-insulated, PVC-sheathed flat cable, consisting of two cores and two layers of sheath, with the appearance of a flat wire.
Purpose and Application:
BVV: Suitable for household appliances, interior decoration, power lighting, instrumentation, and other applications. It is also commonly used in power distribution systems for high-rise buildings such as residential buildings, office buildings, hotels, hospitals, and shopping malls, as well as lighting systems for highways, bridges, and tunnels.
BVVB: Suitable for power transmission lines, control, lighting, and communication lines for mobile electrical equipment such as lifting equipment, cable tracks, transmission machinery, elevators, and telescopic machinery in special locations. It can also be used for connecting and installing mobile mechanical components in enclosed indoor environments.
Installation Methods:
BVV: Typically used for fixed installations. Round cables with smaller cross-sections can also be used for mobile installations.
BVVB: Primarily used for mobile installations. Due to its flat structure, it can be bent more frequently than round cables, resulting in a longer service life.
