3 core Household wire
ZC-RVV线是带接地直埋线，符合中国防火阻燃c级标准，RVV电缆全称铜芯聚氯乙烯绝缘聚氯乙烯护套软电线，又称轻型聚氯乙烯护套软线，俗称软护套线，是护套线的一种。R：代表软线\软结构；V：代表聚氯乙烯绝缘；V：代表聚氯乙烯护套。RVV电线电缆是两芯以上的聚氯乙烯绝缘聚氯乙烯护套软线(两条或上的rv线外加一层护套)。RVV电线是弱电系统最常用的线缆，其芯线根数不定，两根或以上，外面有PVC护套，两芯以上绞合成缆，外层绞合方向为右向芯线之间的排列没有特别要求。按GB 5023.5-1997的规定，额定电压等级分别为300/300和300/500，额定电压250V/450V。阻燃电缆(电线)的生产标准为国家标准GB/T19666-2005。行业标准GA306-2007产品标准。绝缘材料是PVC聚氯乙烯，rvv线附带接地黄绿色线，广泛适用于工厂企业家庭等需要接地线的地方。产品特点及用途适用于交流电压300/500V及以下动力装置、日用电器、仪表及电信设备的电缆。电缆导体的长期允许工作温度为70℃;电缆敷设温度应不低于0℃，阻燃电缆的特点是不易着火或着火后火焰蔓延较慢并能控制在一定的范围内，其使用在对阻燃性能要求较高的场合
    
ZC-RVV wire is ground directly buried wire, in line with China's fire retardant c standard, RVV cable full name copper core PVC insulated PVC sheathed flexible wire, also known as light PVC sheathed flexible wire, commonly known as soft sheathed wire, is a kind of sheathed wire. R: stands for soft wire \ soft structure; V: stands for polyvinyl chloride insulation; V: stands for polyvinyl chloride sheath. RVV wire and cable are more than two cores of PVC insulated PVC sheathed flexible wire (two or more rv wires plus a layer of sheathed). RVV wire is the most commonly used cable of weak current system, the number of core wires is variable, two or more, there is a PVC sheath outside, more than two core twisted synthetic cable, the outer twisted direction is right between the core wire arrangement has no special requirements. According to the provisions of GB 5023.5-1997, the rated voltage levels are 300/300 and 300/500 respectively, and the rated voltage is 250V/450V. The production standard of flame retardant cable (wire) is the national standard GB/T19666-2005. Industry standard GA306-2007 Product standard. The insulation material is PVC polyvinyl chloride, rvv wire with ground yellow green wire, widely used in factories, enterprises, families and other places that need ground wires. It is suitable for the cable of power plant, daily appliance, instrument and telecommunication equipment with AC voltage 300/500V and below. The long-term allowable working temperature of the conductor is 70℃. The cable laying temperature should not be lower than 0℃, the characteristics of the flame-retardant cable is not easy to catch fire or the flame spread slowly after the fire and can be controlled within a certain range, and its use in the occasion of higher flame-retardant performance requirement
