The mechanical properties of phase-to-phase composite spacer on 500 kV compact line were studied by means of computer simulation and experimental methods in this paper.The results show that the theoretical calculation results are consistent with the experimental ones.The composite spacer has a stable post-buckling performance and the composite spacers with core diameter of 30 mm
are appropriate for the 500 kV compact transmission line.Steep front impulse voltage test was carried out on composite spacer after immersing in 0.1% NaCl solution for 48 h.The results show that the electrical insulation performance of composite spacer is reliable.
