葫芦电缆RVV1G，葫芦电缆RVV2G应用安装范围
The range of application:
作为行车电动葫芦连接和控制电缆，适用于干燥或潮湿的室内的各种电气安装。鉴于其特殊的柔性设计，它还适用于无应力缓释可强制引导的左右非连续性运动下的安装或固定敷设。（不作为电梯电缆来回升降使用）。It is the control cable being used for cranes and other appliances in dry or wet environment(indoor). For its special flexibility, it also can be used for  non-continuousinstallation or fixation, but cannot work as elevator cables.
葫芦电缆RVV1G，葫芦电缆RVV2G特性
缆芯之间加有黄麻绳抗拉承载Juted insulated cable rope among cores functions as tensile resistance，芯线与护套间还包有一层无方布缓冲，There is non-woven fabric to release impact between cores and sheath.
在超高长度情况下还有两根承载钢丝绳可供选择（破断拉力可达10.4KN，高度可达150米）In the condition of ultra-height, We recommend to use cable with 2 steels whose broken pulling force reaches 10.4KN and the height 150m .。由于采用了改性的PVC护套比一般橡胶材质更具有抗拉性和抗撕裂强度，又保持柔软性。
产品性能更佳，使用更安全。For the adoption of modified PVC sheath, the product has an excellent properties and safety service.
