Abstract

The invention provides a method for manufacturing a nano-composite tower capable of resisting strong breeze whose speed is greater than 60 m / s. The method comprises 1. preparing composite material, 2. preparing composite rods of a transmission tower, 3. preparing flange hoops, 4. assembling the composite rods and the flange hoops, and 5. sequentially connecting a plurality of composite rods provided with flange hoops to obtain a composite tower capable of resisting strong breeze, wherein flange hoops between ends of two adjacent composite rods are connected through bolts. In the method for manufacturing a nano-composite tower capable of resisting strong breeze whose speed is greater than 60 m / s, nano material and reinforcing material are added in a resin, and the content of glass fiber in composite material is controlled, the mechanical properties of the composite material can be improved, the tensile strength of the manufactured composite rod is 0.6 GPa to 1.0 GPa, and the bending strength is 1.0 GPa to 1.5 GPa. The composite tower manufactured by the method is hydrophobic, anti ultraviolet, acid and alkali resistant, and heat and cold resistant, the service life can be as long as 40 years, so the nano-composite tower can be used as a 110 KV to 220 kV power transmission tower.

Description

technical field [0001] The invention belongs to the technical field of composite tower manufacturing, and in particular relates to a method for manufacturing a nanocomposite tower resistant to strong winds above 60m / s. Background technique [0002] High-voltage transmission line towers are generally made of conductive steel without insulation, which can easily cause lightning strikes, fog flashes, wet flashes and other flashover events, and easily cause tripping accidents, and the cost is high, the weight is heavy, and transportation and installation are inconvenient. It is particularly inconvenient in remote mountainous areas or places with inconvenient transportation. [0003] Composite pole towers have the characteristics of insulation, anti-flash, and lightning strike resistance. For example, the composite 110k pole has double ground wires and the grounding resistance is not greater than 30Ω, and its lightning resistance level can reach more than 100kA. This type of pole...
