Bunuri termice bune și proprietăți de izolare

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 Eficiența termică și generarea de căldură uniformă și curge curent în firul de rezistență la temperatură ridicată .
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 mechanical strength and good adaptability to harsh environments. It can be used for the heating of various liquids and acid-base salts, and also for the melting of metals with low melting point (lead, zinc, tin, babbitt). Users can provide drawings for special design and processing.
Potrivit pentru încălzire aer, ulei, apă, medii chimice, ștampilare la cald, săruri de topire, alcaline și aliaje cu topire scăzută, etc. .
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.
