PVC Pendant Overhead Crane Cables? RVVG
產品標識：Identification
SUPER FLEXIBLE TRAVELING CONTROL CABLE 規格:RVV(2G) 300/500V SHANGHAI ECHU EKM790/791
RVVG

應用安裝范圍
The range of application:
作為行車電動葫蘆連接和控制電纜，適用于干燥或潮濕的室內的各種電氣安裝。鑒于其特殊的柔性設計，它還適用于無應力緩釋可強制引導的左右非連續性運動下的安裝或固定敷設。（不作為電梯電纜來回升降使用）。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.

電纜特性
纜芯之間加有黃麻繩抗拉承載Juted insulated cable rope among cores functions as tensile resistance，芯線與護套間還包有一層無方布緩沖，There is non-woven fabric to release impact between cores and sheath.
在超高長度情況下還有兩根承載鋼絲繩可供選擇（破斷拉力可達10.4KN，高度可達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護套比一般橡膠材質更具有抗拉性和抗撕裂強度，又保持柔軟性。
產品性能更佳，使用更安全。For the adoption of modified PVC sheath, the product has an excellent properties and safety service.
