Abstract
The utility model belongs to transmission equipment, and relates to a structure of a tubular bus, in particular to a full-shielding composite insulating tubular bus. The full-shielding composite insulating tubular bus comprises a tubular conductor, a semi-conductive layer, an insulating layer, an outer shielding layer and an outer insulating sleeve which are sequentially arranged with one another from inside to outside, wherein the insulating layer is wrapped by epoxy resin-impregnated glass fiber, and the outer shielding layer is made from a thin-wall metal pipe. The tubular bus has the advantages as follows: 1. due to the insulating layer which is wrapped by the epoxy resin-impregnated glass fiber, the tubular bus is strong in insulating capacity, and high in reliability; 2. due to a wholly-cast full skirt which is arranged at the end of the insulating layer, the tubular bus not only can increase the creep distance of the end and improve the reliability of a product but also can prevent the moisture from entering into the inner part of the insulating layer to reduce the insulating strength; 3. due to the semi-conductive layer and the insulating layer, the tubular bus can effectively reduce the shielding electromagnetic field and reduce the circuit loss; and 4. due to a capacitance screen which is arranged in the insulating layer, the tubular bus can improve the electric field distribution and the insulating capability.
