BV cables and BVV cables are both common low voltage power cables that are mainly used for fixed wiring, but they have some differences in their construction and usage. The following are the main differences between the two:
1. Different structure
BV cable:
Full name: copper core PVC insulated wire.
Structure: only conductor (copper core) and a layer of PVC insulation, no outer jacket.
Shape: usually single-core, simpler shape.
BVV cable:
Full name: copper core PVC insulated PVC sheathed cable.
Structure: On the basis of BV, a layer of PVC outer sheath is added to form a double layer of protection.
Shape: usually round or multi-core, with more solid structure.
2. Different performance
BV cable:
Better insulation, but lower mechanical strength, suitable for fixed laying, not suitable for exposure to complex environments.
Mainly used for indoor lighting, sockets and other fixed wiring.
BVV cable:
Due to the outer sheath, higher mechanical strength, better abrasion and corrosion resistance, suitable for more complex environments.
Commonly used in occasions that require a higher level of protection, such as industrial equipment, distribution boxes, etc.
3. Different uses
BV cable:
Suitable for dry, no mechanical damage to the indoor environment, such as home improvement, office wiring, etc.
BVV cable:
Suitable for occasions that require additional protection, such as humid environments, industrial places or places that require resistance to mechanical damage.
4. Installation and cost
BV cable:
Relatively easy to install and low cost, suitable for projects with limited budget.
BVV cables:
Slightly more complex to install and more costly, but offers greater safety and durability.
Summary:
BV cable: simple construction, suitable for general indoor wiring.
BVV cable: double-layer protection, suitable for occasions requiring higher protection.
Q: What’s the difference between BV, BVV and BVR?
A: BV is single-core PVC insulated wire; BVV is PVC-insulated and PVC-sheathed round fixed cable; BVR is flexible (stranded) copper conductor with PVC insulation. Choose BVV where fixed, mechanically-protected runs are required.
Q: Can BVV be used outdoors?
A: PVC-sheathed BVV can be used outdoors if protected from direct sunlight and chemicals; for UV or harsh environments, request a UV-stabilized or jacketed option.
Q: What voltage ratings are available?
A: Typical BVV models are rated 300/500V.
