Basic introduction:

Electric heat tracing is an effective pipeline insulation and antifreeze solution, which has been widely used. Its working principle is to dissipate a certain amount of heat through a heat tracing medium, and supplement the loss of the heat tracing pipeline through direct or indirect heat exchange, in order to achieve the normal working requirements of heating, insulation or antifreeze.

Electric heat tracing is a uniform heat release along the length of a pipeline or over a large area of the tank volume, which is different from electric heat tracing where the heat load is highly concentrated at a single point or over a small area; Electric heating has a small temperature gradient and a long thermal stability time, making it suitable for long-term use. Its required heat (electric power) is much lower than that of electric heating.

Advantages:

(1) The electric heat tracing device is simple, produces uniform heat, has accurate temperature control, and can be remotely controlled to achieve automated management.

(2) Heat has explosion-proof, all-weather working performance, high reliability, and long service life.

(3) Electric heat tracing has no leakage, which is beneficial for environmental protection.

(4) Save steel: It does not require the one to two heat tracing pipelines required for steam tracing.

(5) Save insulation materials.

(6) Save water resources, unlike boilers that require a large amount of water every day.

(7) Electric heat tracing can also solve the problem that steam and hot water heat tracing are difficult to solve.

(8) Electric heat tracing design has a small workload, easy and simple construction, and low maintenance workload.

(9) High efficiency, can greatly reduce energy consumption.

Summary:

Electric heat tracing is the only new generation strip constant temperature electric heater that can automatically limit the temperature during heating and adjust the output power according to the temperature of the heated object without any additional equipment; It can be cut short or extended within a certain length range, suitable for temperature control, heat tracing, insulation, and heating of pipelines, equipment, and containers, especially when materials are prone to decomposition, deterioration, crystallization, condensation, and freezing. It has a wide range of applications in the production and processing of petroleum, chemical, power, metallurgy, light industry, food, refrigeration, construction, gas, agricultural and sideline products, and other sectors. It is a technological development direction that replaces steam and hot water tracing.

With the progress of science and technology and the needs of industrial development, traditional heating methods have gradually failed to meet the requirements of modern industry for accurate control and energy efficiency. In this context, self-regulating heating cables have become an indispensable heating solution for many industries with their unique advantages. In this paper, the working principle of self-regulating heating cable and its application in different fields will be discussed in depth.

Self-regulating heating cable is a modern electric heating product made of a special composite structure of conductive core strip and insulating material, combined with materials with positive temperature coefficient (PTC) characteristics. This cable can automatically adjust its output power according to the temperature change of the working environment, maintain a constant temperature, without external control system, to achieve true self-regulation function.

In terms of core principles, the self-regulating heating cable mainly relies on the characteristics of its internal PTC material. PTC material has low resistance at low temperature and generates heat when current passes through; As the temperature increases, the resistance of the material also increases, resulting in a decrease in the current passing through, thereby reducing the heating power, and eventually reaching a preset temperature equilibrium point. This process is completely automatic, fast response, high temperature control accuracy, and is not affected by environmental changes and cable length.

In the field of application, self-regulating heating cable is widely used in petroleum, chemical, electric power, metallurgy, machinery and other industries of pipeline, valve, tank insulation and antifreeze, as well as all kinds of process equipment heat tracing insulation. Due to its reliable performance and ease of installation, the self-regulating heating cable can work stably in extreme weather conditions, effectively preventing freezing of pipes and reducing the efficiency of equipment operation.

In summary, self-regulating heating cables, with their unique positive temperature coefficient materials and intelligent temperature regulation mechanisms, play an important role in improving the operational safety and energy efficiency of industrial facilities. With the continuous progress of technology and the improvement of environmental protection and energy saving requirements, this heating technology will undoubtedly play a more important role in future industrial applications.

As an important accessory, the terminal block is well used in many electrical equipment. So what are the advantages of the terminal block?

Capacitors are relatively weak in reliability among various equipment in substations. The insulation of capacitors is the same as that of other equipment. The internal components generate more heat, but the heat dissipation is not good, and there are more opportunities for internal failures. The combustible content of the materials inside the power capacitor is large, so it is easy to catch fire during operation. Therefore, the operation of power capacitors should create good low temperature and ventilation conditions as much as possible.

The advantage of the terminal block is to facilitate the connection of the wire. It is actually a piece of metal enclosed in insulating plastic. There are holes at both ends for the wire to be inserted. There are screws for fastening or loosening, such as two Wires, sometimes need to be connected, and sometimes need to be disconnected. At this time, they can be connected with terminals and disconnected at any time without welding or twisting them together, which is very convenient and quick. And it is suitable for a large number of wire interconnections. In the electric power industry, there are special terminal blocks and terminal boxes, which are all connected terminals, single-layer, double-layer, current, voltage, ordinary, breakable, etc. A certain crimping area is to ensure reliable contact and to ensure that sufficient current can pass.

 Advantages of terminal blocks:

1. Large wiring capacity, which can adapt to various wiring requirements.

2. The crimping frame and the soldering pin are mechanically decoupled, that is, because the clamping frame and the soldering pin are not connected as a whole, the torque when tightening the screw will not be transmitted to the soldering point.

3. The welding pin has a quadrangular prism shape, and the end shrinks and becomes thinner. When inserting the solder hole, the contact area is increased. Welding liquid is easy to dissolve into the welding hole, and it is not easy to weld.

4. The welding needle is made of copper alloy, and the welding needle has no dirt to ensure the long-term reliability of welding.

5. Tinned solder pins, easy to solder.

6. With heat dissipation channel.

7. The end of the solder pin shrinks and becomes thinner, which is easy to install.
