Abstract

The invention relates to a three-layer co-extrusion ethylene-propylene high-voltage insulating tube bus comprising a tube bus made of T2 red copper. The tube bus comprises a tube bus main body and a tube bus connection part. The tube bus main body is of a hollow cylindrical structure. The tube bus connection part is of an elliptical structure formed by stitching the tube bus main body. The inner walls of the tube bus connection part are in mutual contact with each other and attached with each other in a linear mode. The tube bus main body is connected to the tube bus connection part through a connection component which is of a conical structure. The tube bus main body, the tube bus connection part and the connection component are manufactured through three-layer co-extrusion technology. The design is advanced. The installation is convenient and fast. The three-layer co-extrusion ethylene-propylene high-voltage insulating tube bus is low-carbon, environment friendly, energy saving and high in cost performance. The three-layer co-extrusion ethylene-propylene high-voltage insulating tube bus fills gaps in China. In operation, joints of the bus will not easily loosen or heat. The repairing and maintenance frequency are low. The usage cost is reduced to a great extent.

Description

Technical field [0001] The invention relates to a bus, in particular to a three-layer co-extruded ethylene-propylene high-voltage insulated pipe bus.
