Both BVV and BVR are wires used in the wire and cable industry, primarily for home renovations. Therefore, they are also called home improvement wires. Today, we'll explain what BVV wire is and what the difference is between BVV and BVR wire.
1. What is BVV wire?
BVV stands for copper-core PVC insulated hard-sheathed wire, commonly known as sheathed wire, hard-sheathed wire, or power cord. It is suitable for use as power cord for electrical appliances with an AC rated voltage of 450/750V or below. Its long-term operating temperature does not exceed 70°C. Common cross-sectional specifications include: 0.75 square, 1 square, 1.5 square, 2.5 square, 4 square, 6 square, 10 square, 16 square, 25 square, 35 square, 50 square, 70 square, 95 square, 120 square, 240 square, 300 square, and 400 square.
Characteristics of BVV wire:
(1) The long-term allowable operating temperature of the cable does not exceed 70℃
(2) The ambient temperature when laying the cable should not be lower than 0℃
(3) It has the advantages of acid and alkali resistance, oil resistance, moisture resistance, and mildew resistance
(4) Classification and use: It is used to distribute current and belongs to the wiring type, represented by the letter "B"
(5) It uses copper conductor material, represented by the letter "T"
(6) The insulation material is polyvinyl chloride, represented by the letter "V".
BVV hard sheathed wire has the characteristics of flame retardancy, fire resistance, low smoke and halogen-free; it is suitable for fire protection systems, residential and commercial buildings and industrial distribution circuits.
What's the difference between BVV and BVR cables?
BVV, commonly known as hard wire, consists of round single-core and flat double-core cables. They have both insulation and a sheath, and are commonly used for surface-mounted wiring.
BVR, commonly known as soft wire, is a single-core cable consisting of multiple strands of conductors. It has insulation but no sheath, and is commonly used for connecting electrical appliances and in applications where slight movement is expected.
