What is a wire drawing machine?

The wire drawing machine is an important part of the power distribution line. Its main function is to balance the unbalanced tension of the conductor (ground) wire, stabilize the tower body, reduce the force strength of the tower body, reduce the material consumption of the tower body, and reduce the cost. In the whole construction, try to use the permanent wire pulling machine of the rope pull tower to replace the temporary rope pulling in the whole construction (usually using hemp rope or wire rope).

Ordinary cables are also called grounding cables. It is used for terminal rods, angle rods, support (eliminator) rods, tensioning rods, etc. It bears various stresses on the pole through the connecting rod. The lower end is buried directly in the ground with a pull disc (also known as a ground anchor). In the middle of the wire, there is a gold tool for adjusting the tension (UT-shaped clamp). For power lines with a voltage of 10kV and below, the ordinary cable is at an angle of 45° to the pole. The cable insulator in the wire drawing machine is just one of several installation methods available in the market. It is divided into two parts, the upper part is fixed to the upper part of the rod (weighed rod) and connected with the upper part (weighed the middle or waist of the rod); The lower part includes the ground anchor handle or ring, the wire rod, and the part buried in the ground (including the wire reel and beam), which is called the bottom handle.

High-pile cables are also known as bridge cables, also known as horizontal cables. High-pile wires refer to poles where ordinary wires cannot be installed due to roads or other facilities. If it is limited by the terrain or surrounding environment, you can install a bow cable and pull the wire yourself; In addition, if the terrain is limited and the cable cannot be installed, a pole can be used to balance the tension and stabilize the pole. The use legend and installation requirements of electric poles in actual projects, the specific installation distance and installation requirements are subject to the new regulations and specifications. The function of the pull wire is to balance the forces of all sides of the pole, resist the wind pressure, and prevent the pole from overturning.

An angle drawing machine is installed on the angle rod. It is oriented to the corner bisector outside the corner to withstand the unbalanced moment on the corner bar. In order to balance the unbalanced moment on the corner rod, two corner cables are usually installed on both sides of the corner when the line corner is large. The two corner cables are in the same direction as the original line, and the other is in the opposite direction to the line after the corner. When a larger line segment is selected in the design, the inner corner cable should be installed on the inner bisector of the corner due to the large load on the pole.

Self-drawing is also known as bow wire drawing machine, which is a kind of wire pulling device used when laying ordinary wires unconditionally due to narrow streets or telephone poles too close to the house. When installing, a certain length of support rod should be fixed on one side of the cable to be installed, and the cable should be connected with the cable tray after passing through the support rod. Since the cable can only withstand a small tension, it is generally used for 400V low-voltage distribution lines.
