This is made by depositing a thin film of metal on a cylindrical insulatingsupport.
在圆柱形绝缘体上沉积一层金属薄膜制成。

Such a terminal secure to an insulatingsupport entering more or less into its interior, and I likewise connect the circuit to it inside or, generally, at points where the electric density is small.
The technique of directly buried steam pipeline such as insulation construction, insulating material, outside protective pipe, fixing support, compensator, and steam trap connections is discussed.
