High-voltage bus of composite insulation sleeve and manufacturing method of high-voltage bus

The invention discloses a high-voltage bus of a composite insulation sleeve. The high-voltage bus comprises three conductors, wherein each conductor is arranged in a composite insulation sleeve, a filling layer is filled between the conductor and the composite insulation sleeve, and the three composite insulation sleeves loaded with the conductors are horizontally spaced and fixedly connected by employing multiple groups of composite fixtures. The invention also discloses a manufacturing method of the high-voltage bus of the composite insulation sleeve. The manufacturing method comprises the steps of firstly, fabricating the composite insulation sleeves and the composite fixtures in advance; secondly, inserting the three conductors into the composite insulation sleeves according to phases; thirdly, plugging and filling a gap between an end part of each phase of composite insulation sleeve and each conductor with sealant; and finally, installing and fixing the composite insulation sleeves by employing the mult
