PVV-22 Polyvinyl Chloride Insulated and Sheathed Signal Cable
PVV-22 is a steel tape armored signal cable designed for low-voltage signal transmission, with a rated voltage of up to 250V AC or 500V DC. It features polyvinyl chloride (PVC) insulation and sheathing, combined with an inner steel tape armor layer, providing enhanced mechanical protection against external stress. Suitable for indoor, cable trenches, pipelines, and underground installations, this cable excels in environments requiring resistance to physical impact. The conductor’s long-term operating temperature does not exceed +65°C, and the minimum installation temperature is -5°C, with a bending radius of at least 10 times the cable’s outer diameter to ensure durability. Its robust construction and stable signal transmission make it ideal for applications such as fire alarm systems, telegraph networks, and industrial automation controls.1417
产品特点与优势
PVV22电缆的核心优势在于其双层防护设计：PVC绝缘层有效隔离导体与外界的电气干扰，而PVC护套与钢带铠装则协同提供抗压、防潮及耐腐蚀性能。电缆结构紧凑，线芯直径通常为1.0mm，支持4至61芯的多样化配置，满足不同场景的信号传输需求。其铠装层显著提升了抗拉强度和抗冲击能力，适用于复杂敷设条件，如地下直埋或高振动区域。此外，电缆的阻燃特性进一步保障了使用安全。5912
Features and Benefits
The PVV-22 cable combines PVC insulation and sheathing with steel tape armor, offering dual protection against electrical interference and mechanical damage. Its compact structure supports conductor diameters of 1.0mm and configurations ranging from 4 to 61 cores, catering to diverse signal transmission requirements. The armored layer enhances tensile strength and impact resistance, making it suitable for challenging installations such as direct burial or high-vibration environments. The flame-retardant properties of PVC further ensure operational safety in critical applications.7819
应用场景
PVV22电缆广泛应用于铁路信号系统、工业自动化控制、楼宇安防及能源设施等领域。在铁路场景中，它用于信号联锁和轨道电路；在工厂自动化中，连接PLC、传感器及控制仪表；在建筑领域，则服务于火警报警系统和应急通信网络。其适应性强的特点使其成为需要稳定信号传输和长期可靠性的项目的优选。2621
Applications
