短网：
矿热炉短网是变压器二次侧到电极的大电流线路。一般专指硬母线部分，分铜管式和铜排式两类。现多采用管式短网，管式短网的优点是：
①可以把短网与铜瓦串联成一条水路，冷却水路是：短网→水冷电缆→导电铜管→铜瓦→导电铜管→水冷电缆→短网→调相水冷电缆→变压器管状出线管→调相水冷电缆→短网，然后排出。
②因为短网能用水冷却，短网和水冷电缆的电流密度提高几倍，短网重量减轻很多。
Ore arc furnace short net is high-current lines which secondary side of the transformer to the electrodes. Generally refers specifically to the rigid busbar parts, sub-copper pipe style and copper bar type, The advantages of short tube network are:
①Short net and copper tile can be strung into a waterway, cooling water is: short net →water-cooled cables → conductive brass → copper tile → conductive brass →water-cooled cables → short net →phasing water-cooled cables→variable-pressure tube type electrical conduit-tube → phasing water-cooled cables→short net, and then discharged.
②Because short net can be cooled with water, the current density of short net and water-cooled cables increase several times, short net gets great weight loss.
