The series constant power electric heating cable is a high-standard energy-saving and anti-corrosion electric heating product in the industry. The power bus is composed of two (three) parallel insulated copper wires, and a resistance wire is wound on the insulating layer, and the heating wire is separated by a certain distance. (that is, the heating section is long) connected to the busbar to form a continuous parallel resistance. After the busbar is energized, each parallel resistance generates heat, thus forming a continuous heating belt. Used in combination with other explosion-proof accessories, it can be used in Class II explosion-proof gas occasions. It can monitor the temperature changes through the data display on the explosion-proof power distribution cabinet, and make adjustments in time to meet the physical characteristics of materials under the premise of ensuring safety.
The series constant power electric heating cable is generally designed according to the actual length of the pipeline, so it should be installed strictly according to the design length. Too long or too short will affect the power, so arbitrary shearing is not allowed. When installing the series constant power electric heating cable, press Y Wiring, in order to avoid three-phase current error, it needs to be grounded at the end; the common installation method is: after multiple electric heating cables are laid in parallel and straight, they are fixed radially with fixing tape every 50-80cm. The specific installation factor must be based on the ambient temperature, medium,
Calculate the heat loss such as the pipe diameter, and can control multiple cables at one power point through the temperature control box to achieve centralized control.
The constant power electric heating cable is used in long-distance pipelines (such as oil long-distance pipeline heating, large-scale tank insulation), and the parallel constant power electric heating cable is suitable for large tanks and pipelines that require precise temperature control in explosion-proof areas. The series constant power electric heating cable adopts nickel-chromium alloy wire (the metal bus inside heats up) as the conductor, which cannot be cut. It needs to be controlled by a temperature controller when it is used.
The series constant power electric heating cable is a new type of electric heating product. In addition to the advantages of the general electric heating cable, its biggest feature is that the length of use is long, which is 5-12 times that of the ordinary electric heating cable. For long-distance pipelines, the series constant power electric heating cable is the most ideal heating product.
