three-phase cable

基本解释

However, when applied to long-distance and big-diameter pipes, using of three-phase heating cable is more economic and reasonable and showing more advantage.
但是，当在长距离、大口径管道进行伴热保温时，采用三相带比单相带更经济、更合理、更能显示使用三相带的优越型。
FDP3 three-phase constant watt heating cable provides frozen-prevention and temperature-maintenance of pipelines and valves which is same for FDP2 single-phase constant watt heating cable.
FDP3 型三相恒功率电热带与FDP2型单相恒功率电热带一样，能用于解决管道和阀门等的防冻和保温。
Instead of the time consuming numerical computation, a simplified calculation of the maximum field strength is presented for the purpose of dimensioning the three-phase gas insulated cable.
为确定三相充气管道电缆的尺寸，本文提出利用最大场强的简化计算方法来取代繁复的数值计算。
