The insulation system of an insulation device for plateau permafrost hot water pipes is an insulation set of pipes. The insulation set of pipes has an inner tube and an outer tube. Insulation materials are filled between the inner tube and the outer tube. The insulation system comprises: a bump for HTM, a tank for HTM, and the back and forth pipes for HTM. The back and forth pipes for HTM stick to the outdoor part of the water supply piple closely. At the same time, the back and forth pipes are arranged within the insulation set of pipes. The controller of the control system can analyze the data of the temperature collected by the temperature sensor which is arranged within the pipe system in order to control the cycle of the HTM. In 2009, the transformation of the water supply system for the barracks of the armed police on Qinghai-Tibet Railway Yangtze River and the Kunlun Mountains has been completed through the use of the utility model. The utility model meets the design requirements of being used on permafrost zones above the altitude of 4,500 completely, and solves a series of problems which exist on plateau permafrost zones. The utility model also solves the following problems: the current eletric heating cables are not easy to control; short life. Besides, the utility model is easy to maintain.
