In this paper, it is described the characteristics comparison of LV insulated materials contaminated by the salt vaporization and the particulates. The contact angle of normal PVC is measured $75^{\circ}$ but its of PVC contaminated by the salt vaporization for 500 hours is measured $63^{\circ}$. The contact angle of normal bakelite is measured $66^{\circ}$ but its of bakelite contaminated by the salt vaporization for 500 hours is measured $44^{\circ}$. And the contact angle of normal acrylic resin is measured $65^{\circ}$ but its of acrylic resin contaminated by the salt vaporization for 500 hours is measured $60^{\circ}$. In the surface of insulated materials contaminated by the particulate, the contact angle is decreased. The surface of bakelite is not good as an insulator.
