Narrator : there was a time, a time before cable. 讲述者:曾经有段时光,还没有有线电视的一段时光。
Turner was cable before cable was cool. 特纳是有线电视电缆之前,蛮酷的。
In actual power cable operation, it will be able to cause the local temperature of cable or cable accessories to rise before the cable has electrical failure, resulting in further damage until insulation breakdown. 在电缆运行过程中,电缆线路发生电气故障前都会引起电缆或附件局部温度的上升,从而导致绝缘进一步破坏直至击穿。
Such a migration from free to fee has worked before, when cable operators introduced a subscription model to television. 在有线运营商引入电视订购模式的时候,从免费到收费的转变曾经奏效过。
So, before applying the cable to the power system, it is necessary to develop a research on the quench characteristics of the HTS cable, and to propose a protecting strategy to ensure the safety of the cable. 因此,在高温超导电缆并网之前,有必要对超导电缆的失超特性进行研究,从而提出失超保护策略,保障超导电缆的安全运行。
