The cable has the advantages of water resistance, high-temperature fire resistance, high insulation, long service life, large current carrying capacity, low energy consumption, high strength, high toughness and excellent comprehensive performance.

Description

technical field [0001] The invention relates to the field of high-voltage busbars, in particular to an ultra-high-voltage waterproof and refractory ceramic shielding tubular cast busbar. Background technique [0002] The traditional high-altitude high-voltage line to the transformer in the substation adopts the overhead or underground laying of cables. There are many disadvantages in the traditional transmission method, which are embodied in the following aspects: [0003] 1. The outdoor overhead life of high-voltage cables is short, takes up a lot of space, and has high maintenance costs in the later period; [0004] 2. The underground laying of high-voltage cables is difficult to construct, with high energy consumption and high maintenance costs; [0005] Traditional high-voltage tubular busbar structure and product features: [0006] An insulating dunnage is arranged above the floor-standing steel structure support, and the tubular bare conductors are laid on the insula...

AI Technical Summary

Problems solved by technology

[0003]1. High-voltage cables have a short outdoor overhead life, take up a lot of space, and require high maintenance costs;

[0004]2. The underground laying of high-voltage cables is difficult in construction, high in energy consumption, and high in later maintenance costs;

[0006]Insulating skids are set above the ground steel structure supports, and tubular bare conductors are laid on the insulating skids, wrapped with roll-shaped insulating tapes. Traditional high-voltage tubular busbars It mainly relies on air gap insulation, which takes up a lot of space, and the insulating material used does not have the characteristics of anti-corrosion and high temperature resistance. It takes up a large installation space, the insulation layer is easy to age and fall off, the parameters of the turning position are inconsistent with the straight line, the life is short, and the maintenance cost is high. It is difficult to adapt to the small installation space, large temperature difference, corrosion resistance, product life and safety performance. Highly demanding application fields, and once a short-circuit accident occurs during the application process, it is very likely to cause a large-scale power outage and personal injury or death due to the burning of the power supply line
