Anti-icing iron tower

Abstract

An anti-icing iron tower belongs to the technical field of an electric power iron tower. The iron tower comprises an iron tower body and a protective layer arranged at the external surface of the irontower body. Raw materials of the protective layer comprises, by weight, 20-30 parts of a hydroxyethyl cellulose aqueous solution, 0.1-0.2 part of sulfonated oil, 1-3 parts of propanediol, 3-5 parts of propanediol butyl ether, 60-70 parts of a pure silicone-acrylic emulsion, 0.05-0.1 part of sodium trichlorophenolate, 0.1-0.2 part of polysiloxane, 5-10 parts of polytetrafluoroethylene, 0.1-0.2 part of carbonized castor bean powder, 0.3-0.5 part of hydroxypropyl starch ether, 0.2-0.4 part of nanometer silica, 0.05-0.1 part of aluminium-magnesium silicate, 0.05-0.1 part of maize pollen, and 0.05-0.1 part of cyclodextrin. The pH value is adjusted to 8-9. The anti-icing iron tower is good in anti-icing performance and long in service life, has anti-permeability and water resistance, is light,and is good in flexibility and high in strength.

[0002] Due to the long-term exposure of transmission lines to the wild, certain natural conditions will adversely affect them, such as large-scale low temperature, rain and snow, freezing natural disasters, etc. Among these disasters, the transmission system is the most severely damaged. The paralysis caused huge losses

[0003] The iron tower is the infrastructure used to cooperate with the insulator strings to hang the wires in the high-voltage transmission system. Under low temperature, rain, snow and freezing weather conditions, its surface is prone to ice coating, causing the tower to be subjected to excessive loads, causing local deformation or damage of the iron tower. In severe cases, it may even cause the collapse of the iron tower, destroy the infrastructure of the transmission line, and completely paralyze the transmission line, resulting in a power outage. Low-cost operation. In order to prevent or delay the formation of icing, the existing technology adopts measures such as galvanizing the surface of the iron tower and using steam pipes to heat the tower body. The above measures are costly, difficult to implement, and difficult to popularize and use. However, the existing anti-icing coatings have poor effects and are easily scratched by wind and sand on the surface, which reduces the service life and effect
