First, the dimensions and material properties of imported hot sticks were measured and characterized to determine their mechanical and electrical performance parameters. Then, based on the parameters of the imported products and the existing manufacturing process of hot sticks, simulation design and process optimization were conducted. Finally, a hot stick was fabricated using pultrusion process, and its mechanical and electrical performance were tested. The results show that on the basis of mechanical and electrical physical fields simulations and systematic experimental validation, a domestic lightweight hot stick is successfully developed, and its maximum deflection difference does not exceed 13.2 mm. After 9 times of withstand voltage test under dry conditions, no breakdown, flashover or overheating occur in the hot stick. Moreover, compared with the ordinary domestic hot stick, the prepared hot stick has reduced its unit weight by 29.9%.
