Heating cables are mainly wires and cables for life heating, plant cultivation, pipeline insulation, etc.The heating cable is used as a single -rooted or multiple alloy heat wire as a heating source, high -purity, high temperature, and electrodemine crystal magnesium oxide as a thermal conductivity, seamless continuous stainless steel or copper tube as a sheet, and is made of special production technology.Places with strong corrosion effects can be added with PE or low -smoke -free jackets.
Heating cable application
There are many effects of heating cables, such as for life heating, as well as plant cultivation and pipeline insulation.Next, I will introduce the application of heating cables in detail.Oil wells with heating cables: my countrys crude oil production and taste are not as good as the Middle East, and the self -spraying ability of the mid -term oil well will decline in the midterm of the oil well.Later, the method of solving this problem was to use the heating method.It is to use heating cables to increase the temperature of the pipeline, so that wax is not easy to condense on the pipeline.This is an important application for heating cables.Heating cables for plant greenhouse cultivation: The heating cable used in plant greenhouse cultivation is very different from ordinary cables. Its original is usually made from high -resistance alloy materials, such as copper wires and iron wires.One line of this cable is a copper line, and the other is a high -resistant alloy line.The heating cable for plant greenhouse cultivation is also one of the application of heating cables.
Types of heating cables
Alloys consisting of metals such as copper, nickel, chromium, iron.One conductor of the cable is a copper wire, the other is a high -resistance alloy line and a single solid conductor or twisted structure. The insulation is heat -resistant polyvinyl chloride or ashiline.Most of the sheets use heat -resistant or oil -resistant polyvinyl chloride also requires that the sheets cannot contain harmful metal materials such as lead and cadmium.This type of cable has a large thermal heating power, and can also meet the needs of the users need for use of voltage, delivery length, and thermal power.Therefore, it is mostly used for greenhouse cultivation of plants.If the insulating material is inorganic materials, magnesium oxide is usually used, but other inorganic materials with higher thermal resistance are also used.This heating cable has a lifetime of more than 100 years, and its working temperature will be changed specifically according to the use occasions.Prevent widespread use of snow and airport runways.
Heating cable specification
The specifications of heating cables can generally be divided into three categories.First, according to the use of heating cables, it can be divided into civilian heating cables and equipment heating cables. This division standard is generally divided according to his practicality. Civil heating cables are more common than buying heating cables.Third, the thickness specifications of the workmanship of heating cables can be divided into general heating cables and specific heating cables. This is generally used to distinguish it for special heating cables. Some cables should work in a special working environment, so its specifications are comparedThick.Third, according to the load volume of the cable, it can be divided into high -pressure cables and low -voltage cables.The common specifications of heating cables can be divided into three types of general models, one is TL-7. The amount of cables of this model is a bit higher. Its working temperature is relatively constant temperature, which is 40 degrees temperature.The other is the heating cable of the TL-9 model. This kind of electricity is average, and its working temperature remains about 45 degrees.The last one is the TL-10 model heating cable. The amount of electricity of this cable is low, and his working temperature is about 50 degrees.Their thing in common is that they can work at 220V voltage, and the DC current is basically 60A, which guarantees the sustainability at work.
Heating cable installation
1. The tube to be buried and the wiring box of the temperature controller to be left and the instrument that limited the temperature is 73mm eighty -six wiring boxes.Leave the position of the power cord on the wall before the wall, the height of the temperature controller is about 1.4 meters away from the ground, and the temperature limiter wiring box is buried directly below it.About 40 cm on the ground.2. Installation of the power cord.The power cord is suitable for copper wires with 2.5 mm specifications.The power of the room lock should not be too large, otherwise you must choose the right power cord to work normally.3. The laying of the thermal insulation board should be flat, and they should be tightly tightly. Pay attention to the places of the wall and the ground.4. Laying the wire mesh, the distance should be selected at the 10x10cm iron wire mesh, and then it should be applied neatly.5. The well -used insulation and miscellaneous strips are good, and the tail must be cut off
