BV Cable-BVV/BVVB
BVV/BVVB cable is a high-quality power transmission cable widely used in residential, commercial and industrial environments.
The structure of BVV wire is relatively simple, from the inside to the outside, it is the core, insulator, and sheath. Simply put, the outermost layer of the sheath wraps several BV wires, which are divided into copper core PVC insulated PVC sheathed round cable and copper core PVC insulated PVC sheathed flat cable
Share:
The multi-core structure of Shenxing cable is usually composed of 2 or more copper wires, using high-quality copper wires, PVC insulation, and PVC sheath for triple protection. This structure not only ensures the flexibility of the cable, but also effectively improves the conductivity.
Widely Use:
Residential electrical systems
BVV/BVVB cables are commonly used for power wiring in residential buildings. They are suitable for indoor power distribution systems, especially for connecting power supply, lighting and power sockets.
Industrial control systems
In industrial environments, BVV/BVVB cables are used to connect motors, machines and control panels to ensure stable operation of production lines.
Construction projects
In construction projects, BVV/BVVB cables are used for power distribution and facility power supply. Their high pressure resistance and wear resistance make them very suitable for maintaining stable performance in long-term use.
Communication and network equipment
BVV/BVVB cables are also used in some communication and network equipment. They are used for power transmission between communication rooms and equipment to ensure stable power during data transmission.
Advantage:
BVVB wire, also known as flat twin and earth cable.
Space-saving design: BVVB wire consists of two insulated conductors (twin) and an additional uninsulated conductor (earth) laid flat side by side. This design allows for a compact and space- saving installation.
Easy installation: Makes it easier to handle and install compared to round cables.The flat shape also helps to minimize the risk of cable twisting or tangling during installation.
Versatility and Cost-effective Compatibility with accessories: BVVB wire is compatible with a wide range of electrical accessories, such as switches, sockets, and junction boxes.
