Background technique

Electricity is an energy powered by electric energy. It was invented in the 1870s. The invention and application of electric power set off the second industrialization climax and became one of the three scientific and technological revolutions in the world since the 18th century in human history. Since then, technology has changed people. The large-scale power system that appeared in the 20th century is one of the most important achievements in the history of human engineering science. It is a power production and consumption system composed of power generation, power transmission, power transformation, power distribution and power consumption. The primary energy is converted into electricity through mechanical energy devices, and then the electricity is supplied to various users through power transmission, transformation and distribution.

Overhead lines mainly refer to overhead open lines, erected above the ground, and are transmission lines that use insulators to fix the transmission wires on the towers standing on the ground to transmit electric energy.

There are many kinds of pay-off racks. The following are the pay-off racks used in the wire and cable industry, which can be divided into: active pay-off racks, passive pay-off racks, vertical pay-off racks, horizontal pay-off racks, shaft-type pay-off racks and wireless pay-off racks. Shaft pay-off stand.

The traditional pay-off device is mostly a winding shaft assembly, which is manually or mechanically rotated to wind and store or release the cable. However, in the process of taking up or paying off the wire, the cable is wound on the winding shaft by its flexible force. If the winding angle is not limited, it will be unpredictable, not only the winding effect is messy, and there is no craftsmanship at all, but also this winding method will leave too many holes inside, which increases the volume of the bobbin and also means that some cables inside It is in a state of load and compression, which will easily affect the life of the cable over time.
