Speed differential anti fall device ensures smooth progress of Jinjie 330 kV power transmission and transformation project

The Jinjie 330kV Power Transmission and Transformation Project is located in Yulin, Shaanxi Province. It is a high-quality line consisting of a 330kV substation and transmission lines, which can transmit high-quality electricity from Shaanxi to nearby industrial parks through substations and cables, providing reliable power energy guarantee for the development of factories and enterprises in the park.

The power workers responsible for the construction of the Jinjie 330 kV power transmission and transformation project stand on the tower, while the ground personnel use control ropes and a 130 ton crane to lift the assembled wire and ground wire brackets to the installation position. These five power workers then align the tower materials with the installation holes at the four corners of the tower body and tighten the wire and ground wire brackets with bolts.

The installation of wires, brackets, and tower materials in the Jinjie 330 kV power transmission and transformation project is all high-altitude work. Power workers work under the protection of safety belts and speed difference fall arresters throughout the process. The safety belts are responsible for connecting the human body, and the fall arresters are responsible for timely locking the steel wire rope. The combination of the two protective devices ensures the personal safety of power workers in all aspects, thereby ensuring the smooth progress of the Jinjie 330 kV power transmission and transformation project.
