Добри топлинни проводимост и изолационни свойства

The electric heating tube is a tubular electric heating element which is composed of a metal tube spiral resistance wire and crystalline magnesium oxide powder. The high-temperature resistance wire is evenly distributed in the stainless steel seamless tube, and the crystalline magnesium oxide powder having good thermal conductivity and insulation performance is filled in the void portion, and the structure is not only advanced, but also has high thermal efficiency и равномерно генериране на топлина и токови потоци в проводника с висока температура .
The electric heating tube is filled with a heating wire in a seamless metal tube (carbon steel tube, titanium tube, stainless steel tube, copper tube), and the gap portion is filled with a magnesium oxide powder having good thermal conductivity and insulation, and then processed into a tube. Various shapes that users need. The utility model has the advantages of simple structure, high thermal efficiency, good Механична якост и добра адаптивност към сурови среди . Може да се използва за нагряване на различни течности и киселинно-базни соли, а също и за топене на метали с ниска точка на топене (олово, цинк, калай, babbitt) . потребителите могат да осигурят рисунки за специален дизайн и обработка .
Подходящ за отоплителен въздух, масло, вода, химически среди, горещо щамповане, топене на соли, алкали и ниски сплави за топене и т.н. .
In a 380 volt three-phase four-wire circuit, the voltage between any two live wires is 380 volts, and any one of the live and neutral wires can form 220 volts. This system can form three power sources: single-phase 220 volt power supply, single-phase 380 volt power supply, and three-phase 380 volt power supply.
