<p>PROBLEM TO BE SOLVED: To make it unnecessary to remove the insulation gas in a tank by forming a tank almost in the cylindrical shape and fitting almost at the equal intervals T-type cable heads for three phases in the circumferential direction of the tank. SOLUTION: Fitting seats 15a to 15c for fitting T-type cable heads 13a to 13c for three phases are provided to a tank 3 at the equal intervals along the circumferential direction. The fitting seats 15a to 15c for three phases are arranged in the radial direction with an angular interval ofθin the layout of inverse V-shape where height of fitting seats 15a, 15b is lower than the fitting seat 15b in different height of adjacent phases. As the value ofθ, a desired value may be set. As a result, it is no longer required to remove the insulation gas of tank and to fill again such gas.</p> |
