Problems solved by technology
[0002] Traditional transmission towers generally have defects such as heavy weight, perishability, corrosion or cracking, poor durability, short service life, difficulties in construction, transportation and operation and maintenance, and are prone to various safety hazards
Therefore, with the development of new material technology and its preparation process, a new material is urgently needed to replace the traditional pole material. At present, the fiber spiral winding technology is often used in the market, and this process can only be limited to tap water pipes, pressure vessels and other products. , can not meet the deflection requirements of the pole

Embodiment Construction
[0024] HMC material has the characteristics of high strength, light weight, corrosion resistance, fatigue resistance, durability and electrical insulation performance, and is very suitable for manufacturing transmission towers. Compared with steel poles, HMC poles mainly have the following characteristics:
[0025] 1. Light weight. The density of HMC is 1700~2000kg / m 3 , while the density of steel is 7800kg / m 3 , At the same volume, the weight of HMC is 1 / 4 to 1 / 3 of steel. Light weight is one of the outstanding advantages of HMC towers. Due to the light weight, transportation and construction and installation costs can be greatly reduced. It is especially suitable for the use of transmission lines in mountainous areas and soft soil areas.
[0026] 2. High strength. The strength of the main direction of HMC can reach more than 800MPa, which is much higher than the yield strength of ordinary steel. At the same time has excellent fatigue resistance.
[0027] 3. Corrosion ...

Abstract
The invention relates to a method for producing a pole used for electricity transmission line, in particular relates to a method for producing a high strength composite pole. The method includes the following steps: a, positioning a steel hollow pole on the rotating shaft of a rotational stand, then starting up a transmission device to drive the rotating shaft to rotate; b, coating vinyl ester bond on the surface of the steel hollow pole; c, after coating, winding high strength unidirectional cloth; d, after the first winding is ended, winding a second layer of unidirectional cloth; e, after the second layer of unidirectional cloth is wound, pasting a tailored roving cloth on the unidirectional cloth, and after two layers of roving cloth are pasted, continuously burying the long fiber soaked in a steeping vat between the roving cloth and the unidirectional cloth; f, winding two layers of unidirectional cloth again until the thickness of the FRP reaches 4-4.5mm, and waiting for solidifying; g, avoiding the FRP exothermic peak and starting the winding of the next unidirectional cloth, repeating until reaching the desirable thickness; in this way, a composite pole is formed. With the method, high strength poles used for transmission lines can be produced from composite material.
Description
technical field [0001] The invention relates to a production method of electric poles used in power transmission lines, in particular to a production method of high-strength composite material electric poles. Background technique [0002] Traditional transmission towers generally have defects such as heavy weight, perishability, corrosion or cracking, poor durability, short service life, difficulties in construction, transportation, operation and maintenance, and various potential safety hazards. Therefore, with the development of new material technology and its preparation process, there is an urgent need for a new material to replace the traditional pole material. At present, the fiber spiral winding technology is often used in the market, and this process can only be limited to tap water pipes, pressure vessels and other products. , can not meet the deflection requirements of the pole. Contents of the invention [0003] The object of the present invention is to seek a ...
