How much power is 1 meter for electric tracing? It depends on the specifications and models of the product, usually the electric cable body or the manual will be marked. The power indicated is the "rated power", i.e. the heating power at 10°C.

The calculation formula of power consumption of 1 meter (per meter) of electric heat tracing: P=W/t means that the power is equal to the work done per unit time, and the total work W=Pt=UIT=UP; W: stands for "work", t: for "time", P: for "power", I: for "current", U: for "voltage", and R: for "resistance". For example, the calculation of power consumption: W = Pt = 25 watts per meter of power × 24 hours = 600 watts. When calculating the power consumption of electric heat tracing, it should be noted that the "rated power" is the heating power at 10 °C, and the power consumption will be affected by the use environment and heat tracing requirements.

How long is the electric cable used? This question depends on the length of use of each type of electric trace. For example, the length of the self-limiting temperature electric cable can be 100 meters; That is, the total length of the electric trace that is connected together by a single or intermediate junction box cannot exceed 100 meters, that is, less than or equal to <> meters, and if it exceeds the length of <> meters, it is necessary to increase the circuit. The length of use of each specification and model electric trace is different, such as the length of constant power electric trace can reach hundreds or thousands of meters, and there will be relevant parameters in the technical description of the product.

Electric traces that are used in a range of lengths and are single or interconnected are usually set up as a loop. How many meters can electric heat trace connect? It can also be understood as the number of meters that a circuit can connect to this specification model? Or use self-limiting temperature electric heat trace as an example, if the pipeline electric heat tracing insulation project needs to use a total of 160 meters of electric heat trace, then no matter how they are connected, at least two circuits need to be set up, tips: interconnection between the heat traces is recommended to use an intermediate junction box.

General inquiry electric heat trace is divided into dealers and end users, general manufacturers from the model given by the customer, sometimes some models are universal, manufacturers at a glance to know which kind of electric heat tracing. However, some models are the models compiled by the manufacturer themselves, at this time, the customer needs to confirm with the other company the use of the electric heat trace, temperature requirements, whether explosion-proof and anti-corrosion and other parameters can be quoted. As far as dealers are concerned, many users have models and direct inquiries.

In addition, end-user inquiries for electric heat tracing are generally selected according to the on-site heat tracing project. At this time, manufacturers need to communicate with users: electric heat tracing use occasions, temperature requirements, pipe diameter, length of pipeline, whether explosion-proof and anti-corrosion and other parameters. Because there are many models and specifications of electric heat traces, the model or use needs must be clear when quoting, so that the manufacturer can recommend the electric heat trace model suitable for you to use. Only if the electric cable is selected, it can be quoted according to the model.

The quotation also needs to clarify whether it includes tax, and the general manufacturer issues a 16% VAT special invoice. If we want to buy a large number of products, the tax amount is also quite large, when contacting the manufacturer, try to declare with the manufacturer that the price that needs to be reported is tax-included.

Moreover, there is the problem of freight, when there are many goods, and in remote areas, freight is not cheap. In addition, which shipping method to choose, pick-up or home delivery, this is also a question to consider. Therefore, these small elements need to be coordinated and communicated between both parties in order to obtain a quotation for the positive return of the electric trace.

Tropical tracing is another name for electric heating products, such as electric heat tracing, electric tropical actually refers to the same product, is the use of electric energy into heat energy for pipeline frost protection. The conventional voltage is 200V, 380V, and other required voltages can also be produced, which needs to be confirmed with the manufacturer. So how many watts is 220 meters of 100v heat tracing, let's introduce it to you.

Because the power of the cable is not the same, there are 20w/m, 30w/m, 45w/m, etc., of course, if the customer has special power requirements, the manufacturer can be customized according to the needs of users. How many watts is 220 meters of 100v heat tracing, you need to see how much power you choose, such as 20w/m is 2000w, 30w/m per meter is 3000w. Therefore, in addition to the temperature, the selection of heat tracing is also particularly important, which involves how much power the power load of the use occasion can carry, if the power is not large enough, it is necessary to expand the on-site power load.

The above is about the introduction of 200v cable 100 meters of watts of power, the actual application of the user can let the manufacturer technical staff help select and calculate the power, if you still do not understand anything, you can consult us at any time will give you a detailed answer.

Tropical cable is another name for electric heat tracing, can also be called electric tropics, is the use of electric heat conversion principle for pipelines and other equipment antifreeze insulation products, it can be according to the pipeline and other equipment in the environment and temperature requirements to choose the corresponding model. In the process of use, users are more concerned about electricity consumption, such as how much electricity is used in 10 hours of 12 meters of heat trace, let's introduce it to you.

How much electricity does a 10m trace use in 12 hours

How much electricity is used in 10 meters of the cable for 12 hours we can calculate by calculating, its calculation formula: W = Pt, W means "work", P means "power", t means "time", here we also need to know what is the power per meter of the cable used, and then substitute the formula to calculate, assuming that the power of the cable we choose is 35 watts per meter, 10 meters is 350 watts, that is, 350 watts× 12 hours = 4200 watts, 1 kilowatt hour is one degree of electricity, Then the electricity consumption of 10 meters of heat trace for 12 hours is 4.2 degrees. Of course, this refers to the conventional situation, the actual application will also be affected by a variety of factors, and the specific needs to be calculated according to the actual application.

The cable can be turned on and off

Can the cable be turned on and off at times, of course, the answer is yes. This may be done to save power due to the customer's lack of knowledge of the heat trace application, but it is important to note that this will not only not save power, but also cause waste of energy. The power consumption of the cable is very small when it does not need to be insulated, and turning it on again after turning it off requires a relatively large amount of power to restart, and turning on and off for a long time will also cause system failure and affect use.

Due to the different site environment and installation needs, electric heat tracing is also divided into different models, for example, according to the voltage can be divided into 24V, 36V, 110V, 220V, 380V, etc., if there is a special requirement of voltage, you can also require electric cable manufacturers to customize. Is it the same for different voltage electric cable wiring, and how to wire 380V electric heat trace.

Generally, the common electric heat trace is a single straight line or wrapped on the insulated object, coated with aluminum foil electric heat trace directly attached to the process pipe wall, and installed insulation layer outside, such as pipeline equipment. Among them, according to whether the winding electric cable is superimposed, consider the use of self-limiting temperature electric cable when the design temperature allows. However, heat tracing in high temperature environment requires the use of constant power electric tracing, and can not be superimposed winding, so special attention should be paid to installation, constant power electric tracing can be specifically divided into single-phase and three-phase electric tracing, generally can be divided into 220V, 380V, choose which electric cable can be according to process requirements and use environment. For example, the drawing to the electric cable with the switch circuit breaker, contactor, etc. are all three-phase, then it can be recommended to use three-phase constant power electric trace, its internal three wires are live wire, generally star-delta connection, through the electric cable special junction box for power and electric cable connection, after installation, generally leave an electric cable in all the two-way and three-way connection after extension of 100mm, convenient for later inspection, with three-phase is generally star delta connection.

Electric heat trace wiring installation is very important, many electric trace faults are caused by improper installation, so if the user will not install, can let the electric heat tracing manufacturer on-site guidance or ask a professional installation team to install, to avoid the installation of irregular installation caused by the electric heating system failure can not be used.

In winter, we often hear the term electric heat trace, but because many people do not understand it, they do not know what electric heat trace is. Electric heat tracing is a thermal insulation system that is energized and heated, and the main uses are equipment antifreeze insulation, temperature maintenance, snow melting and ice melting of buildings, heat compensation of production processes, etc., because it does not achieve the effect of heating, so it is called "heat tracing". Electric heat trace models can be roughly divided into two categories: self-limiting temperature electric heat trace and constant power electric heat trace.

Self-limiting electric heat traces are also strip temperature-limiting electric heaters with high positive temperature coefficient (PTC) resistivity of their heating materials. Evenly extrude semi-conductive polymer composite PTC material between two parallel metal cores, and wrap a layer of insulation material as a sheath to obtain a basic electric cable that can be used, and if necessary, shielding and protective layers can be added.

The parallel constant power cable power bus is two parallel insulated copper wires, which are wound on the inner insulation layer and connected to the bus at regular distances (i.e., "heating section length") to form a continuous parallel resistance. When the bus bar is energized, each parallel resistor heats up, thus forming a continuous heating cable.

Series constant power electric tracing is an electric heating product made of core wire heating element, that is, the current passed on the core wire with a certain resistance, the core wire emits Joule heat, due to the resistance of the unit length of the core wire and the current passed. It is equal in the entire length, and the heat generation everywhere is also equal, so it is suitable for heat tracing and insulation of long-distance pipelines, powered by a power point.
