RVVB铜芯聚氯乙烯绝缘聚氯乙烯护套扁型连接软电缆产品介绍
一、中文版
RVVB铜芯聚氯乙烯绝缘聚氯乙烯护套扁型连接软电缆是一种广泛应用于低压电气连接的柔性线缆。该产品采用高纯度无氧铜导体，表面经精密拉丝工艺处理，确保优异的导电性能与抗弯折能力。导体外层挤包聚氯乙烯（PVC）绝缘层，其厚度均匀性控制在±0.1mm以内，可有效隔离导体与外部环境的接触。独特的扁型结构设计使线缆在狭小空间布线时具有显著优势，平行排列的线芯间距经过优化计算，有效降低电磁干扰。
该电缆护套采用改性聚氯乙烯材料，具备良好的耐油污、防潮及阻燃特性，通过特殊配方使表面硬度达到85 Shore A，既保证机械防护性能，又维持了线体的柔韧性。产品适用于额定电压300/500V及以下工作环境，长期允许工作温度为-15℃至+70℃，短时耐受温度可达105℃（不超过5小时）。
主要应用于小型家电内部接线、工业控制柜设备连接、办公自动化仪器电源传输等场景。其扁平结构特别适合需要频繁移动或弯曲的场合，如数控机床拖链系统、舞台灯光设备等。选购时建议根据实际载流量需求选择截面积规格（常规范围0.5-2.5mm²），并注意观察绝缘层与护套的粘合紧密程度。
市场价格受铜材期货行情波动影响较大，建议定期关注有色金属交易市场动态。国内主要生产基地位于长三角和珠三角地区，选择制造商时应重点考察企业是否具备完整的原材料检测体系及成熟的生产工艺控制能力。

RVVB Copper Core PVC Insulated PVC Sheathed Flat Flexible Connecting Cable
The RVVB flat connecting cable is a flexible low-voltage cable widely used in electrical connection systems. Featuring oxygen-free copper conductors processed by precision wire drawing technology, this product ensures outstanding conductivity and bending resistance. The PVC insulation layer with thickness tolerance controlled within ±0.1mm provides reliable isolation between conductors and external environment.
Distinctive flat configuration offers notable advantages for installation in confined spaces. The optimized parallel core spacing effectively minimizes electromagnetic interference. The modified PVC sheath material demonstrates excellent oil resistance, moisture protection and flame retardancy. With surface hardness reaching 85 Shore A through specialized compound formulation, the cable maintains both mechanical protection and flexibility.
Rated voltage 300/500V and below, this cable operates within -15℃ to +70℃ temperature range, capable of withstanding short-term exposure up to 105℃ (max. 5 hours). Its applications cover internal wiring of household appliances, industrial control cabinet connections, and power transmission for office automation equipment. The flat structure is particularly suitable for scenarios requiring frequent movement or bending, such as CNC machine tool drag chains and stage lighting systems.
When selecting specifications, consider current-carrying requirements (standard cross-sections 0.5-2.5mm²) and inspect the adhesion quality between insulation and sheath. Price fluctuations correlate closely with copper futures market trends, requiring regular monitoring of nonferrous metal trading data. Major domestic manufacturers are concentrated in Yangtze River Delta and Pearl River Delta regions. Procurement should prioritize suppliers with comprehensive raw material inspection protocols and mature production process controls.
This product complies with general safety requirements for flexible cables, featuring easy-strip design for terminal connections and color-coded insulation for phase identification. Customization services including length cutting and special packaging are available through formal manufacturers to meet project-specific demands.
