This paper study on some enhanced spacers and then get it `s static mechanical properties through the finite element analysis software of ANSYS. The research use the horizontal tension and compression load and radial force load that spacer can bear to simulate the conductor icing and short-circuit working condition. The research considered the spacer`s material nonlinear and the advanced contact nonlinearity of spacer multibody systems. Compared with experiment result,it shows that the weakest part is the spacers ` wire clamp. Rubber mat can reduce the collision between components and play a role in energy storage. The research result provide a good reference for the spacers` design、improvement and usage. And it lays the foundation for the fine simulation analysis of transmission line system.
