Precautions During Installation Of Pre-twisted Wire

During the installation process, workers wrap armor rods transmission line around the railway wire to be connected in a prescribed manner. When wrapping, make sure that each turn of armour rod fits tightly to the wire surface. For example, in the contact network, wrap armour rod in transmission line around the contact wire, starting from one end, and wrap it around and around until armor rods conductor completely covers the prescribed length. This process needs to be carried out strictly in accordance with the installation standards to ensure that the tightness and number of turns of the winding meet the requirements.
