电站中的电缆具有量多而重要性强的特点。一般电厂主厂房里的电缆沟道、隧道、大都有漏水和积水现象。有的电缆隧道因常年积水,降低了电缆的绝缘性能,引起电缆放炮,严重影响电厂的安全运行。虽然近些年来设计和施工时也想了些办法来防漏排水,但因电缆隧道渗漏的原因较多,涉及到设 The cable in the power station has many features and is of high importance. Cable channels, tunnels, and large water pipes in the main power plant of a power plant have leakage and water accumulation. Some cable tunnels have accumulated water for many years, which reduces the insulation performance of cables and causes cables to launch fire, which seriously affects the safe operation of power plants. Although in recent years, design and construction have also considered some measures to prevent leakage and drainage, there are many reasons for the leakage of cable tunnels.
