As a effective pipeline (storage tank) insulation and anti -freezing scheme with thermal cable, it has been widely used.Its working principle is to distribute certain heat through the heat media, and supplement the loss of the accompanying heat pipe through direct or indirect heat exchange to meet the normal work requirements of heating, insulation or anti -freezing.In the 1970s, the US energy industry proposed the use of electricity with electricity to replace steam accompanying heat.Since the development of electricity with heat, it has developed from traditional constant power accompanying heat to the self -control temperature accompanying heat with conductive plastic as the core.
The principle of working with heat cable
The core of the heat cable is a polymer semiconductor material with a PTC effect.The working principle is: fill the polymer semiconductor material in the middle of the two parallel lines as the core wire. After the power supply is connected, the current passes through one wire transmitted to another wire to form a circuit.Among them, the semiconductor that is added with conductive carbon grains to the polymer material is the key to thermal heating: when the temperature around the heat pipeline is low, the conductive plastic generates microlinage contraction, the carbon particle connection formation circuit can pass the current, accompanyThe thermal cable starts to work; when the temperature is high, the conductive plastic generates micromolecular expansion, and the carbon particles gradually separate, resulting in the interruption of the circuit, the increase in resistance value, the automatic power output with the heat cable, and the reduction of heat.When the surrounding temperature becomes cold, the polymer material is returned to the contraction state of the micromics, and the carbon particles are connected accordingly to form a circuit.
How to install with thermal cable
First, when installing the line, place the entire roll with the heat line and the roll on the bracket, and place it near one end of the loop circuit in the hotline.2. When letting the line, you should follow the pipeline direction to avoid pulling the accompanying hot cable with vigorously. During the launch process, you should avoid pedals or heavy objects and debris on the accompanying cable.Third, the design drawing is set with the thermal cable. Starting from the power wiring box point, along the pipeline or the outer wall of the container, use a glass tape or aluminum tape to fix the heat electricity "cable on the pipe or container.If the requirements of the figure are not required in the design diagram, it shall be fixed according to the prompt of the installation manual to follow the lower half of the pipeline as much as possible.
Accompanying hot cable import brands
With the imported brand of heat cable, choose the brand with thermal cable imported brand.After reading the information, I still asked me why? This is too slow to respond.The hot cable import brand is not a problem for the high price and price, and do not choose the imported cable without choosing the price.In this way, you will regret it! Choose a brand with thermal cable.
Passion with thermal cable
Next, I will lead you to take a look at the low -temperature temperature control with the heat cable developed and developed by Anhui Zhongsheng (Group) Electric Co., Ltd..This cable is widely used in civilian solar energy, geothermal heating, and pipelines of industrial enterprises such as fire, oil, chemical, steel, and electricity.The cable is suitable for ordinary areas, dangerous areas and corrosion areas.Product models are: DWL (DXW, DKW, ZKWD, DBW) Corresponding foreign model BTV series temperature level: Low temperature (D) series structure type: Basic type (J), Basic Antimony type (J2), shielding explosion -proof type (P), Shielding anti -corrosion type (P2), explosion -proof protection (PF), explosion -proof anticorrosive (PF2) voltage level: 12V, 24V, 36V, 110V, 220V, 380V nominal power: 10W/m, 15W/m, 20W/m, 20W/m, 25W/m, 30w/m
