<p>PROBLEM TO BE SOLVED: To obtain an insulation bus system, wherein the replacement of its insulation bus with a new one is made possible, without the takeout of its insulation bushing and the connection work of its insulation buses is readily made possible without precise centering operation or using special tools. SOLUTION: An insulation bus system has T-type bushings 20 attached respectively to the casings of a plurality of electrical appliances provided in parallel with each other, insulation buses 30 whereby the adjacent T-type bushings 20 are connected, and insulation cylinders 40, each of which covers the coupling portion of the insulation bus to the T-type bushing 20. In this case, the length of the insulation bus 30 is made larger than the length of the insulation bus 30 is made larger than the summed length of the two insulation cylinders 40 which cover the coupling portions of the two end portions of the insulation bus 30, and the bushing-side diameter of each insulation cylinder 40 is made larger than its insulation-bus side diameter, and furthermore, each insulation cylinder 40 is so formed that it can be moved from the side of the insulation bus 30 to the side of the coupling portion.</p> |
