As most domestic power plants use high-sulfur coal as the main fuel, China ’s sulfur dioxide emissions are increasing year by year.Electric heating cable for power plant A large amount of sulfur dioxide emissions make China the third largest acid rain pollution country and region in the world after North America and Europe.
In order to protect the environment that depends on it, Platinum Rhodium Thermocouple reduce sulfur emissions and harm, power plant flue gas desulfurization technology is receiving widespread attention, and the environmental protection industry is gradually taking shape. For this reason, Anbang has specially developed a series of self-limiting electric heating and heating cables for desulfurization and environmental protection projects in power plants. pt100 thermocouple And other phenomena. At present, this series of products are used in many domestic power plant desulfurization projects, and users have responded well.

Our special electric heating cable for power plants is a special electric heating cable produced for power plants or pipelines with steam sweeping lines. Its product feature is the addition of a heat insulation layer between the sheath and the shielding layer of the electric heating cable. On the pipe wall of the sweep line, the heat insulation method such as the use of heat insulation clamps for the installation of the electric heating cable of the pipeline with the steam sweep line is solved.
Electric heat tracing is the use of electric heat tracing equipment to convert electrical energy into heat energy. Through direct or indirect heat exchange, it supplements the heat lost by the heat tracing equipment through the insulation material, and adopts temperature control to track and control the medium in the heat tracing equipment. Temperature to keep it at a reasonable and economic level.
Not only save installation and maintenance costs, but also because the electric heating cable is directly installed on the pipe wall, so that the heat tracing effect is more direct and effective, thereby reducing energy consumption and operating costs. Therefore, the special electric heating cable of the power plant is the best type of electric heating cable for pipelines with steam sweeping lines.
Five, technical parameters
1. Heat-tracing structure: conductive thermoplastic on the inner layer, double-layer flame-retardant polyolefin on the outer layer and a shielding layer;
2. Temperature range: the maximum exposure temperature is 85 ° C, the maximum surface temperature is 85 ° C, the maximum maintenance temperature is 65 ° C, and the minimum use temperature is -40 ° C;
3. Construction temperature: minimum: -5 ℃;
4. Thermal stability: After cycling back and forth from 10 ℃ to 99 ℃ for 300 times, the heating value of the heating cable is maintained above 90%;
5. Bending radius: 25.4mm at 20 ° C and 35.0mm at -30 ° C;
6. Insulation resistance: When the length of the heating cable is 100m and the ambient temperature is 75 ° C, use a 2,500VDC shaking table for 1 minute. The minimum value of the insulation resistance (between the lead and the shield) is 1200MΩ.
