Flat PVC Insulated & Sheathed Cable (BVVB/BLVVB) | 450/750V Low Voltage Power Cable | Copper or Aluminum Conductor | IEC 60227

Premium Flat PVC Sheathed Power Cable (BVVB / BLVVB) – 450/750V Building Wire

I. Product Construction and International Equivalence

Our BVVB/BLVVB series cable is a multi-core, flat-shaped building wire designed for maximum safety and ease of installation. The robust construction provides superior protection compared to single-insulated wires, making it a reliable choice for fixed power distribution.

• BVVB (Copper Conductor): Features high-purity Solid Copper (Class 1) conductors.

• BLVVB (Aluminum Conductor): Features durable Solid Aluminum conductors, offering a cost-effective solution for power transmission.

• International Equivalent: This construction is often similar to the internationally recognized IEC 60227-10 cable type.

Construction Details:

1. Conductor: Solid or stranded Annealed Copper (BVVB) or Aluminum (BLVVB).

2. Insulation: PVC (Polyvinyl Chloride) compound applied to each individual core.

3. Assembly: Two or three insulated cores laid parallel in a flat configuration.

4. Outer Sheath (Jacket): A final layer of durable PVC compound covering the assembled cores, providing double insulation.

II. Key Features and Performance

A. Safety and Reliability

• Enhanced Fire Safety: The PVC compounds used are typically Flame Retardant (FR) to limit the spread of fire in building environments.

• Moisture & Abrasion Resistance: The outer PVC sheath protects the inner insulation from physical damage, moisture, and mild chemical exposure, ensuring long-term performance.

• High Dielectric Strength: The 450/750V rating ensures the cable can safely handle standard low-voltage distribution and surge conditions.

B. Installation & Thermal Benefits

• Optimal Heat Dissipation: The flat profile has a larger surface-to-volume ratio than round cables, which facilitates better heat management and often results in a higher effective Ampacity (current rating).

• Fixed Installation: Engineered for permanent wiring, suitable for installation inside conduits, cable trays, or concealed wiring in walls and ceilings.

III. Technical Specifications (BVVB / BLVVB)

Optional Feature: High-Performance Sheathing (Custom Order)

For applications requiring high heat or oil resistance, Nylon (Polyamide) jacketing can be custom-applied to the insulation layer, similar to THHN/THWN specifications. Contact our sales team for custom orders.
