Aiming at the characteristics of closed fixtures such as large size, heavy weight and difficulty in high‐altitude operation, this study proposed a design method to improve the clamping apparatus for replacement of insulator strings in the ultra‐high‐voltage (UHV) transmission line. After modelling through the finite element method, the mechanical properties of the clamping apparatus are analysed to determine the structure with the fixtures of carbon fibre composites. The proposed clamping apparatus will have the characteristics as high strength, high modulus and low weight, so that if applied in the UHV transmission line, the working efficiency will be improved and the labour intensity will be reduced.
