    Abstract: An insulation device includes an insulating part, and at least one conductive part located on at least one surface of the insulating part, wherein the at least one surface of the insulating part facing the at least one conductive part has central concave shape. A longitudinal section of the at least one conductive part includes a straight portion in the middle and two curved portions extending outwardly from both ends of the straight portion. The curved portions satisfy: { x = A ⁡ ( ϕ + 1 2 ⁢ ( e ( ϕ + i ⁢ φ ) + e ( ϕ - i ⁢ φ ) ) ) y = A ⁡ ( φ + 1 2 ⁢ i ⁢ ( e ( ϕ + i ⁢ φ ) - e ( ϕ - i ⁢ φ ) ) )   .
