Description
Although typical flexible belt-type electrical heating devices have good heating and moisture-proof performance, such existing technologies lack perfect leakage protection and technical means to prevent overheating operation, so it is difficult to meet the technical index requirements of explosion-proof products. The electrical explosion-proof electric tracing cable provided by the utility model adopts a fully enclosed insulation protection layer structure on the one hand, and a temperature control thermal switch on the other hand to ensure that the product can work stably within a set temperature range. The product has ideal work safety and reliability.
An explosion-proof electric tracing cable for electrical appliances, which is characterized in that the heating belt comprises an electric heating belt core (1) made into a belt shape, and a temperature sensor is arranged on the electric heating belt core and is electrically connected to the electric heating component of the temperature control The heat-sensitive switch (12), and the high-temperature-resistant insulating sleeve (2) of the fully enclosed wrapped core and its temperature-controlled heat-sensitive switch, the two electrical connection ends (5) of the series-connected loop with the core pass through the high-temperature insulation Set of settings.
