AWG 4/0 Xhhw Wire Aluminum Xhhw-2 Fr Sr Cable Xlp Insulation Building Wire 600V​ The AWG 4/0 XHHW Aluminum Cable—including XHHW-2, FR (Flame Retardant), and SR (Sunlight Resistant) variants—represents a heavy-duty solution for 600V building wiring. Crafted from 1350-H19 aluminum (61% IACS conductivity), its 19-strand (2.1mm diameter) design delivers 230A continuous current at 90°C (XHHW-2) and 195A at 75°C (standard XHHW).​ XLPE insulation ensures exceptional durability: 1.8mm thickness with 22kV/mm dielectric strength, resisting chemicals, moisture, and abrasion. XHHW-2 handles -40°C to 90°C, while FR variants meet UL 94 V-0 flammability, and SR models feature 2.0% carbon black for UV resistance (10,000-hour sunlight endurance).​ Compliant with UL 44 and ASTM B230, this 4/0 AWG cable (3.8kg/m) suits heavy-load applications: main service entrances, large motor feeds, and commercial building distribution. Its flexibility (8× OD bend radius) facilitates conduit/tray installation, offering 40% cost savings over copper, making it ideal for industrial and high-rise construction.

H05V-R H07V-R Cable 1.5mm² 2.5/4/6/10/16/25mm² Stranded Copper PVC Covered Housing Wire for Building​ H05V-R and H07V-R cables stand as premium stranded copper housing wires, featuring robust PVC coverage, tailored for diverse building electrical needs. Available in 1.5mm², 2.5mm², 4mm², 6mm², 10mm², 16mm², and 25mm², they cater to residential, commercial, and institutional buildings with precision.​ The stranded copper core ensures exceptional flexibility and conductivity, simplifying installation in walls, ceilings, and conduits—critical for navigating complex building structures. PVC insulation and sheathing deliver superior resistance to moisture, abrasion, and flame, complying with EN 50525 standards for safety and longevity. H05V-R, rated 300/500V, excels in low-power circuits like lighting and small appliances, while H07V-R (450/750V) handles heavy loads such as HVAC systems and main distribution lines.​ From 1.5mm² for intricate wiring to 25mm² for high-capacity distribution, each size guarantees reliable performance. SEO-optimized keywords—“stranded copper housing wire,” “PVC covered,” and key voltages—make them easily discoverable for builders and electricians seeking code-compliant, durable building wiring solutions.

Flame Retardant Cable ZR-BV ZR-BVR 450/750V Electrical Wire Building Summary​ The Flame Retardant Cable ZR-BV and ZR-BVR, rated for 450/750V, are high-quality electrical wires specifically engineered for building electrical systems, combining reliable flame-retardant performance, stable electrical conductivity, and strong adaptability to diverse installation scenarios. As core components in residential, commercial, and public building power distribution, these cables address the critical need for fire safety in enclosed electrical environments— a top priority for architects, electrical contractors, and facility managers.​ ZR-BV (single-core solid copper conductor flame-retardant PVC insulated wire) and ZR-BVR (single-core stranded copper conductor flame-retardant PVC insulated wire) differ primarily in conductor structure, catering to distinct installation requirements. The ZR-BV features a solid copper conductor, which offers excellent structural stability and is ideal for fixed installations with minimal bending, such as hidden wiring in wall cavities, ceiling conduits, or floor ducts. Its rigid structure ensures consistent performance over long-term use, with low risk of conductor breakage from vibration or minor external stress. The ZR-BVR, by contrast, uses a stranded copper conductor— composed of multiple fine copper strands twisted together— delivering superior flexibility. This makes it perfect for installations requiring frequent bending or routing through tight spaces, such as inside electrical switchboards, around furniture, or in renovation projects where wiring adjustments may be needed.​ Both cable types meet the "ZR" (flame-retardant) standard, meaning they can inhibit flame propagation and self-extinguish when the fire source is removed, in compliance with GB/T 19666 (Chinese standard for flame-retardant cables) and IEC 60332-1-2 (international standard for vertical flame propagation). This flame-retardant property is critical for building safety: in the event of an electrical fault (e.g., short circuit), the cables prevent the spread of fire, minimizing damage to the building structure and providing valuable time for evacuation.​ With a rated voltage of 450/750V, these cables are suitable for low-voltage power distribution systems in buildings, powering lighting fixtures, household appliances, office equipment, and small-scale mechanical devices. They also boast excellent electrical performance: the high-purity copper conductors (≥99.95% purity) ensure low DC resistance (e.g., ≤1.83Ω/km for 2.5mm² ZR-BV at 20°C), enabling efficient current transmission with minimal energy loss. The PVC insulation layer is resistant to aging, moisture, and moderate chemical exposure, ensuring a service life of over 20 years in typical building environments.​ Compliant with global safety and environmental standards (including RoHS 2.0 for restricted substances), the ZR-BV and ZR-BVR cables offer a cost-effective, safe, and versatile solution for building electrical systems. Their clear differentiation in flexibility and fixed vs. adjustable installation suitability makes them a go-to choice for meeting the diverse needs of modern building projects.
