Example Embodiment

[0023] In order to make the content of the present invention easier to be understood clearly, the following further describes the present invention in detail based on specific embodiments in conjunction with the accompanying drawings.

[0024] The bus duct is a closed metal device composed of copper and aluminum bus bars. It is used to distribute high power to the various components of the distributed system. It has increasingly replaced wires in indoor low-voltage power transmission trunk projects. The cable, and the start bus is necessary in the bus system. The cast shell in the existing start-end bus bar generally has good electrical insulation performance, but its mechanical strength and chemical resistance are poor, and its service life is short.

[0025] See figure 1 , figure 2 In view of this, this embodiment provides a fully insulated pouring start-end bus bar, the start-end bus bar including a conductor 1, a pouring shell 2 and a branch connection row 3. There are five con

Abstract

The invention discloses an all-insulation pouring starting end bus, and relates to the technical field of power equipment. The bus comprises conductors, a pouring shell and branch connecting bars, thenumber of the branch connecting bars is consistent with the number of the conductors. One end of each conductor is positioned outside the pouring shell, and the other end of the conductor extends into the pouring shell and is connected with the end, located in the pouring shell, of the corresponding branch connecting bar, and the pouring shell is prepared from, by mass, 10% of quartz powder, 7% of light calcium carbonate, 5% of high-temperature aluminum oxide, 15% of refined calcined kaolin, 60% of resin and 3% of curing agent. The pouring shell is formed by accurately preparing and pouring various inert inorganic minerals according to strict process requirements, the tensile strength, the elongation at break, the chemical resistance and the electrical property of the pouring shell are improved, the chemical resistance is improved, the water absorption is reduced, and the shock resistance is improved.
