H07V-U 1.5-6mm² Single Core Copper Cable - 450/750V PVC Insulated

Cross-sectional Size: The cable covers a cross-sectional range from 1.5mm² to 6mm², tailored to adapt to electrical devices of different power levels. The 1.5mm² cable, being relatively slender, is suitable for low-power equipment. As the cross-section increases, the 6mm² cable can carry larger currents, catering to high-power devices. Cables with different cross-sections have distinct appearances—the larger the cross-section, the thicker the outer diameter—allowing users to quickly identify specifications through visual inspection for easy selection based on actual needs.

Rated Voltage: With a rated voltage of 450/750V, this parameter defines the cable’s voltage-bearing range in power transmission. 450V is applicable to fixed wiring scenarios with an AC rated voltage of 450V or below, such as lighting and general socket circuits in homes. 750V can be used in temporary power supply or industrial equipment connection scenarios below 750V, compatible with most low-voltage distribution systems to ensure safe and stable power transmission.

Current-carrying Capacity: A key indicator of the cable’s current transmission capability, current-carrying capacity varies significantly with cross-sectional size. The 1.5mm² cable has a current-carrying capacity of approximately 14-20A, sufficient for small household appliances (e.g., rice cookers, microwave ovens) and lighting equipment. The 2.5mm² cable, with a capacity of 18-25A, can connect office devices like printers and projectors. The 4mm² cable, reaching 25-35A, provides stable power for high-power appliances such as air conditioners and electric water heaters. The 6mm² cable, with a capacity of 35-45A, is suitable for powering small industrial equipment (e.g., small machine tools, fans). Note that current-carrying capacity is affected by environmental temperature and laying methods: higher temperatures reduce heat dissipation, lowering capacity; heat-restrictive laying methods (e.g., conduit installation) also require capacity reduction to prevent overheating hazards.

Insulation Performance Parameters: The cable has an insulation resistance of ≥100MΩ·km, ensuring excellent insulation to prevent current leakage. It also passes a 1500V voltage withstand test, remaining unbroken for 1 minute, further verifying reliable insulation and ensuring electrical safety.

Conductor Parameters: The single-strand conductor is made of high-purity electrolytic copper, with a diameter tolerance controlled within ±0.02mm to ensure accurate cross-sectional area. High-purity copper offers superior conductivity with low resistivity, reducing energy loss during transmission and improving efficiency. Additionally, the single-strand conductor has high mechanical strength, resisting stretching and 挤压 during construction for easy installation in various environments.

Industrial Sector:

Commercial Scenarios:

Household Scenarios:

Conductor Material: The conductor uses high-purity electrolytic copper (≥99.95% purity), offering excellent conductivity to reduce resistance, energy loss, and improve transmission efficiency. Refined to remove impurities and oxides, the copper ensures a smooth surface for stable conductivity. The single-strand structure provides high mechanical strength, resisting breakage during construction for easy cutting, bending, and connection in diverse environments.

Insulation Material: The insulation layer is made of polyvinyl chloride (PVC) with uniform thickness (0.6-1.2mm), increasing with cross-section to provide effective insulation for varying current loads. PVC offers Chemical Resistance against acids, alkalis, and salts, extending service life. It has UL94 V-0 flame retardancy, slowing combustion and limiting flame spread to aid fire safety. Additionally, it resists aging, operating stably at -15℃ to 70℃ and withstanding oil, moisture, and other external factors for long-term reliability.

Style: The single-core circular design offers advantages: uniform insulation thickness ensures consistent performance without weak points; the Single Core facilitates threading through pipes and wiring in concealed walls or trunking, reducing installation difficulty; and the circular shape eases storage and transportation, saving space.

Copper Smelting and Purification: High-quality copper raw materials are smelted and refined to remove impurities (e.g., iron, lead, zinc), achieving purity ≥99.95%. High-purity copper is foundational for excellent conductivity.

Wire Drawing: Purified copper is heated and drawn into single-strand wires with precise diameters, controlled within ±0.02mm via strict regulation of speed, temperature, and die size. The wire surface is smooth, free of cracks or scratches, with diameter tailored to cross-sectional requirements.

Insulation Extrusion: PVC insulation is applied via continuous extrusion. Dried PVC granules (to prevent bubbles) are melted and uniformly coated around the Copper Wire using precise temperature, speed, and pressure control. Insulation thickness deviation is ≤0.05mm, with no bubbles or wrinkles, and thickness adjusts with cross-section for proper insulation.

Cooling and Solidification: Cables with insulation are cooled in water tanks (20-30℃) to solidify PVC quickly, avoiding internal stress from rapid cooling that could affect performance.

Printing and Labeling: Product information (model, cross-section, voltage, manufacturer, date, standards like EN 50525-2-21) is printed on insulation using wear-resistant ink for clear, durable identification and traceability.

Quality Inspection: Each batch undergoes over 20 tests (conductor resistance, insulation resistance, voltage withstand, thickness, flexibility) to meet standards, ensuring only qualified products leave the factory.

Packaging Materials: Short-length cables (100m, 200m) use plastic reels—lightweight, cost-effective, corrosion-resistant, and strong enough to secure cables. Long-length cables (500m, 1000m) use wooden reels for high strength and stability, withstanding heavy loads. Both are wrapped in moisture-proof, wear-resistant plastic film to shield against dust, moisture, and damage.

Packaging Methods: Cables are neatly wound on reels with controlled tension to avoid twisting or overlapping. Wrapped reels are sealed in plastic film; wooden reels have metal edges for added strength. Labels on packaging indicate model, cross-section, length, date, batch, and manufacturer for easy identification.

Packaging Labels: Clear labels include product details and warning symbols ("Do Not Crush," "Moisture/Sun Protection," "Keep Away from Fire," "Handle with Care") to guide proper handling. They also display standards (e.g., EN 50525-2-21) and certification marks, highlighting quality.

Transportation Modes: Short-distance domestic transport (≤500km) uses road transport (vans, trucks) for flexibility and speed, suitable for small or urgent orders. Long-distance or large-volume shipments use rail transport for high capacity, low cost, and stability. Export orders use sea freight (containers) for large volumes or air freight for urgency.

Transportation Precautions:

Transport Tracking: A robust system allows customers to track shipments via order or logistics numbers. Logistics updates (location, progress, ETA) are provided, with customer service relaying information for preparation.

Shipment Process:
