★注： 實際選用時應根據(jù)管道長度、散熱量、工作電壓和芯線數(shù)，計算芯線截面而定。
Note:When actually applying,choose suitable type cable according to the pipe lenght,heat loss,work voltage,number of core wires.and core wire's section areas.
Mainly applying to thermal insulation of single long legnth pipe,The longest use length with one power suppply circuit from hundreds meters to thousands meters.
