Abstract: The embodiment of the present disclosure provides a cutout which can comprise a top contact assembly being capable of electrically coupled with a first electric cable; a bottom contact assembly being capable of electrically coupled with a second electric cable; an insulator assembly secured to the top contact assembly in a first end thereof, and secured to the bottom assembly in a second end thereof opposite to the first end; and a tube assembly having a fuselink placed therein for conducting electricity between the top contact assembly and a bottom contact assembly. The bottom contact assembly has a bottom contact member which is capable of electrically coupled with the second electrical cable at one end thereof, and removeably coupled with the tube assembly at the other end thereof, such that a current path is formed from the second electrical cable to the tube assembly via the bottom contact member.

Abstract: Embodiments of the present disclosure provide an electrical insulating material and a method for preparing an electrical insulating element. The electrical insulating material contains matrix component, filler component and liquid hydrophobic component; wherein the matrix component comprises saturated styrenic block copolymer. The electrical insulating material based on saturated styrenic block copolymer has good UV resistivity, tracking and erosion resistance, thermal stability, and lower dielectric constant and dielectric loss. It is also easy and cheap for producing.
