應(yīng)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(nèi)的各種電氣安裝。鑒于其特殊的柔性設(shè)計(jì)，它還適用于無應(yīng)力緩釋可強(qiáng)制引導(dǎo)的左右非連續(xù)性運(yùn)動下的安裝或固定敷設(shè)。（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(hù)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(dá)10.4KN，高度可達(dá)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(hù)套比一般橡膠材質(zhì)更具有抗拉性和抗撕裂強(qiáng)度，又保持柔軟性。
產(chǎn)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.
