What is RDC constant power series heater?

RDC constant power series electric heating belt is an electric heating related product with the core wire as the heating body. When the current flows through the core wire with a certain resistance, the core wire generates Joule heat. Because the resistance per unit length of the core wire is equal to the passing current in the whole length, the heating capacity everywhere is equal. It is not easy. For example, the increase of the length of parallel type leads to low tail output power. Compared with other electric heating belts, its characteristic is its long application. It is 5-13 times longer than the application of series constant power electric heating belt and automatic temperature control electric heating belt. Therefore, it is very suitable for cold prevention, thermal insulation and heat tracing of long-distance transmission pipelines, large and medium-sized tanks, oil storage tanks and other manufacturing industries such as petroleum (crude oil), chemical plants, electric power engineering and ports, The system is powered by one power point.

Working principle of constant power series electric heater

Constant power series electric heating has three forms: single core, dual core and triple core. The utility model relates to a constant power series electric heating belt, which relates to an electric heat tracing product with a wire core as a heat generator. Since the resistance per unit length of the wire core and the current passing through the wire core are constant, according to Joule's law, the current continuously emits energy through the conductor to form an electric heating belt with continuous and uniform heating and constant output power.
