Research on a new type of high-efficiency composite polymer odor bird repellent for overhead transmission lines

Abstract Aiming at the special needs of transmission lines for repelling birds, this article conducted stress experiments on various bird repellent spices, selected and compounded highly effective bird repellent spices; PVDF particles were used as the main carrier material, and dry-wet phase conversion technology was adopted. Supplemented by various functional agents, we have researched and developed a new type of high-efficiency solid bird repellent with slow release, weather resistance and long-term effect. The real-time monitoring results show that the bird repellent has a strong odor and has an obvious repellent effect on birds. It can prevent the birds from approaching the iron tower containing the bird repellent or even returning to the nest. It is environmentally friendly, efficient and long-lasting, easy to install and use, good weather resistance, etc., superior to the existing similar bird repellent products used in the power system, and meets the bird repelling requirements of the power system.
