It is found that comparing with compact single circuit transmission mode, T-type compact transmission mode of two circuits on the same tower and conventional transmission mode of two circuits on the same tower, the transmission mode of two circuits with same phase sequence in the same tower window need narrower corridror width, and the radio interference and audible noise caused by this transmisison mode is relatively lower, especially, the corona loss is reduced evidently, thus better economic and social effects can be obtianed by applying this transmission mode in a short distance under a centain condition.

从走廊宽度、电磁环境、潜供电流和防雷特性4个方面对750 kV同塔同窗同相序紧凑型输电方式进行了分析，发现与单回紧凑型、同塔双回T型紧凑型及同塔双回常规型输电方式相比，采用同塔同窗同相序紧凑型输电方式所需的走廊较小，无线电干扰和可听噪声相对较低，尤其是电晕损失明显减小，采用这种方式在一定条件下可获得较好的经济效益与社会效益。
