Abstract

PURPOSE:To improve the resistance to the decomposition product by means of a specified film provided on the far infrared ray transmitting window. CONSTITUTION:A filmlike cover 8 made of polyethylene or the like which is allowed to transmit far infrared ray with a wavelength exceeding 4mum while highly resisting to the arc decomposition product of insulating gas such as SF6 gas is applied on the sheath side inner surface of the far infrared ray window plate mounted to the flange of the sheath 1 as a metal pressure vessel. Accordingly, with the opening or the closing of the mobile element 4 of the control switch 10, an arc is generated between the contactor 3 and the mobile element. Even if any reactive compound is generated from the decomposition of the insulating gas such as SF6 gas full in the sheath 1, the film 8 prevents the corrosion of the window plate 7.
