BLVV铝芯聚氯乙烯绝缘聚氯乙烯护套圆型电缆产品介绍
一、产品结构与特性
BLVV铝芯聚氯乙烯绝缘聚氯乙烯护套圆型电缆采用优质铝导体作为导电核心，导体表面经特殊工艺处理，确保电流传输稳定高效。绝缘层采用高纯度聚氯乙烯（PVC）材料，具有均匀的绝缘厚度和良好的介电性能，能有效阻隔电流外泄风险。外护套选用增塑型聚氯乙烯复合材料，通过精密挤出工艺形成连续致密的保护层，兼具柔韧性与机械强度。
该电缆设计为圆型结构，截面圆整度高，便于施工时的穿管敷设和弯曲操作。铝芯材质赋予产品轻量化特性，相比同规格铜芯电缆减轻约40%运输重量。外层护套提供多重防护功能：耐酸碱腐蚀性能可适应复杂环境，防潮特性确保在湿度较高场所仍能保持稳定工作状态，抗紫外线添加剂延长户外使用年限。
二、性能优势
- 环境适应性：工作温度范围覆盖-15℃至+70℃，短期耐受温度可达+160℃
- 安全防护：双层PVC结构形成可靠绝缘屏障，降低线路间电磁干扰
- 经济实用：铝导体成本优势明显，适合大长度固定敷设场景
- 维护便捷：护套表面光洁度高，积尘易清理，延缓材料老化
三、典型应用领域
• 建筑配电系统：适用于干燥或潮湿的室内外固定布线

四、使用注意事项
安装时应保持弯曲半径不小于电缆外径6倍，避免机械应力集中。直埋敷设需配合防护套管使用，穿越高温区域建议增加隔热措施。定期检查护套完整性，及时清理表面积聚的化学物质。
BLVV Aluminum Core PVC Insulated and Sheathed Round Cable Product Introduction
I. Product Structure & Features
BLVV aluminum core PVC insulated and sheathed round cable features precision-engineered aluminum conductors with optimized surface treatment for stable current transmission. The high-grade PVC insulation layer demonstrates uniform thickness and excellent dielectric properties, effectively preventing current leakage. The outer sheath, crafted from specially formulated PVC compound, provides continuous mechanical protection through advanced extrusion technology.
The circular construction ensures smooth surface continuity, facilitating conduit installation and bending operations. Aluminum core significantly reduces product weight by approximately 40% compared to equivalent copper cables. The composite sheath delivers multi-protection capabilities: corrosion resistance adapts to harsh environments, moisture-proof design maintains performance in humid conditions, while UV inhibitors extend outdoor service life.
II. Performance Advantages
- Environmental adaptability: Operational temperature range -15℃ to +70℃ with short-term tolerance up to +160℃
- Safety assurance: Dual-layer PVC structure creates reliable insulation barrier with reduced EMI
- Cost efficiency: Aluminum conductor offers economic advantage for long-distance fixed installations
- Maintenance convenience: Smooth sheath surface eases cleaning and slows material degradation
III. Application Scenarios
• Building power distribution: Suitable for indoor/outdoor fixed wiring in dry or damp conditions
• Lighting systems: Commercial complexes, industrial plants, and public facility illumination
• Equipment power supply: Machine tools, conveyor systems, and industrial device connections
• Agricultural electrification: Waterproof circuits for greenhouses and irrigation systems
• Temporary power: Exhibition venues and event sites requiring provisional power transmission
IV. Usage Guidelines
Maintain minimum bending radius of 6x cable diameter during installation. Use protective conduits for direct burial and install thermal insulation when crossing high-temperature zones. Regularly inspect sheath integrity and promptly remove surface contaminants.
