PVC Insulated And Sheathed Round Cable (BVV)

Tongda's BVV cable is designed for building power distribution, lighting systems and internal wiring of electrical appliances. It is suitable for scenarios with strict requirements on safety and durability, such as hotels, hospitals, and commercial complexes. With double-layer PVC insulation sheath (300/500V) and IEC 60227 standard certification, it can operate stably in an environment of -15℃ to +70℃ for a long time, solving the problem of insulation layer aging caused by moisture and friction, and reducing the rework rate of the project.

PVC Insulated And Sheathed Round Cable is designed for fixed wiring in commercial buildings (such as hotel corridor power distribution, hospital operating room lighting system) and internal lines of industrial equipment. The double-layer PVC structure shows advantages in the following scenarios:

Reliability of concealed projects: The tensile strength of the sheath is ≥12.5N/mm² (GB/T 2951.11), suitable for pre-embedded concrete and metal pipe penetration, reducing the risk of insulation damage caused by construction friction.

Stability in humid environments: Passed the IEC 60811-2-1 humidity resistance test, suitable for environments with humidity >85% such as basements and cold storage.

Fast project delivery: Supports full-size standing inventory from 1.5mm² to 35mm², and 15-day port delivery (Ningbo Port/Qingdao Port) for orders below 10,000 meters.

Compatible with multiple national standards

Basic certification: IEC 60227, GB/T 5023.3

Extended certification: CE (EN 50525), CCC (China Compulsory Certification), SAA (AS/NZS 5000.1) available on demand, supporting EU, Middle East, and Southeast Asian project applications.

Flexible configuration options

Number of cores and colors: 1-5 cores optional, supporting 7 sheath color codes such as red/yellow-green, suitable for three-phase five-wire (TN-S) system.

Quality traceability system: Each cable axis comes with an independent traceability code, and the raw material batch (Jiangxi Copper C1100 electrolytic copper), production time (72-hour aging test record), and test report (TUV Rheinland third-party certification) can be queried online.

What is the difference between BV and BVV?

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.
