BLVV (Blu-ray Vibration Ventilation) is a round wire with a silvery-white aluminum core conductor. A layer of insulating material, called an insulation layer, is evenly and tightly wrapped around the conductor to prevent contact with the outside world, which could cause leakage, short circuits, or electric shock. Its long-term operating temperature is 70°C. Below, we'll explain the uses of BLVV wire.
BLVV stands for aluminum core, PVC insulated, and PVC sheathed round wire. The "L" designates aluminum.

Applications of BLVV Wire
Suitable for power plants, household appliances, power transmission projects, electromechanical and hydropower installation projects, instrumentation, and telecommunications equipment with AC voltages of 450/750V and below.

Product Features
1. Voltage levels: 450/750V, 300/500V, 300/300V;
2. The long-term allowable operating temperature of the wire should not exceed 70°C;
3. For wires with an outer diameter (D) less than 25mm, the allowable bending radius should be no less than 4D;
For wires with an outer diameter (D) greater than 25mm, the allowable bending radius should be no less than 6D;
4. Flame-retardant wires must pass the GB/T18380.3-2001 and ICE 60332-3 bundled wire combustion tests.

Material Advantages
1. Jacket: Because aluminum cores are used outdoors and for temporary wiring on construction sites, higher requirements are placed on the wire's wear and aging resistance. Therefore, Jinhaotai uses double-layer insulation protection. This not only improves the cable's insulation performance, but also ensures normal operation in harsh environments and a longer lifespan.
2. Aluminum Conductor: Utilizing a high-grade aluminum alloy core, through a special compression process and annealing treatment, the cable ensures excellent electrical conductivity, creep resistance, and oxidation resistance. Due to its low price and lightweight, aluminum-core cables are gradually replacing copper-core cables in more applications.
3. Insulation: Utilizing high-standard flame-retardant materials, compared to conventional insulation materials, it offers superior flame retardancy and low smoke production. It produces minimal halogen gas during combustion, minimizing harm to others.
4. For safety reasons, select a conductor cross-section appropriate for the current carrying capacity based on the line current and ambient operating temperature.
5. During use, the cable surface must not come into contact with heat sources.

Common Specifications
BLVV aluminum-core cables are typically distinguished by the cross-sectional area of the central metal conductor of the insulation.
(For example, the cross-sectional area of a 4-square-meter BLVV aluminum-core cable is 2.24 mm in diameter. Using the circular area formula, S = π * r * r = 3.939 square mm).
Common BLVV aluminum wire sizes include: 1.5 sq. m, 2.5 sq. m, 4 sq. m, 6 sq. m, 10 sq. m, 10 sq. m, 16 sq. m, 25 sq. m, 35 sq. m, 50 sq. m, 70 sq. m, 95 sq. m, 120 sq. m, 150 sq. m, 185 sq. m, 240 sq. m, 300 sq. m, 400 sq. m, etc.
05
Precautions
1. Before use, please inspect the insulation or outer jacket of the wire to prevent damage from transportation or improper storage, which could affect performance.
2. The wire should be laid at a room temperature no lower than 0°C. The bend radius should be no less than 6 times the wire's outer diameter to prevent cracking.
3. The long-term operating temperature of the wire should not exceed 70°C.

Additional Information
BV—a single-core wire consisting of one or seven (BV10 and above) copper wires. It is relatively hard and is also called hard wire. It is the most commonly used type of wire in home wiring.
BVR – A single-core wire consisting of seven or more copper wires twisted together. This is relatively soft and is also called a flexible wire. BVR makes it easier for electricians to run through conduit when wiring has many bends.
RVV – RV wire is a single-core wire consisting of 30 or more fine copper wires twisted together. It is even softer than BVR and is generally not used for home decoration. RVV is a soft-sheathed wire consisting of two, three, or more RV wires sheathed together.
BVVB – A rigid-sheathed wire consisting of two or three BV wires sheathed together. It is generally used as an open-ended wiring.
