China Coal Geology Group Co., Ltd. was established in 1994 with the approval of the former Economic and Trade Office of the State Council. It is a modern central enterprise under the jurisdiction of the State-owned Assets Supervision and Administration Commission of the State-owned Assets Supervision and Administration Commission. It has a registered capital of 1 billion yuan. The Geological Group focuses on the five main businesses of geological exploration and mining development, ecological construction and people's livelihood geology, urban infrastructure and services, biological material research and development and manufacturing, financial geology and investment operation, and is committed to creating a resource exploration with industry expertise in the field of new energy minerals And the development enterprise group.

The pipelines and valves of China Coal Geological Group's coal yard are easy to freeze due to the low temperature in winter, which affects the normal operation of the equipment. Therefore, it is necessary to prevent freezing and heat preservation of the pipelines and valves of the coal yard. The tropical zone can meet its requirements. The self-limiting temperature electric heating cable can automatically control the temperature, and it can also be installed in an overlapping manner, which is very suitable for the antifreeze and thermal insulation of complex pipelines and valves.

The self-limiting temperature electric heating cable is flexible and can be easily attached to the surface of the pipeline. The metal shielding net on the outer layer of the electric heating cable can prevent static electricity from being generated and safely grounded. It not only improves the overall strength of the electric heating cable, but also The role of heat transfer and heat dissipation. At the same time, the electric heating cable also has the characteristics of fast heat conduction, uniform temperature and low cost, convenient installation and simple maintenance. It has become an ideal product for pipeline insulation in winter.
