**产品介绍：**

电加热带又称自限温电加热带或温控加热电缆。电加热带是一种由导电高分子复合材料（塑料）、两根平行金属导线及绝缘护套组成的扁带状电缆。其特点在于导电高分子复合材料具有正温度系数 “PTC” 特性，且呈并联连接。它能够根据被加热系统的温度变化自动调节输出功率，并自动限制加热温度。

所谓 “PTC” 特性，即正温度系数效应，是指材料的电阻率随温度升高而增大，并在某一温度范围内急剧上升的特性。自限温加热线可在一定范围内任意截短或接长，允许多处交叉重叠，无需担心高温热点及烧毁问题。因此，自限温电加热带具有以下优点：

– 自限温电加热带能够对应被加热系统自动调节输出功率，不会因自身发热而烧毁，可根据实际所需热量进行补偿，是新一代节能型恒温加热器。
– 低温启动迅速，温度均匀，各部位均可根据被加热部位的温度变化自动调节。
– 安装简便，维护简单，自动化程度高，运行维护成本低。
– 安全可靠，用途广泛，不污染环境，使用寿命长。

Product Name: Self-regulating Heating Cable
Conductor Cross-section: Tinned 2*2.0 square
Product Introduction: The electric heating tape is also known as the self-regulating electric heating tape or temperature-controlled heating cable. The electric heating tape is a flat strip cable composed of a conductive polymer composite material (plastic), two parallel metal wires, and an insulating sheath. Its characteristic is that the conductive polymer composite material has a positive temperature coefficient “PTC” characteristic and is connected in parallel. It can automatically adjust the output power according to the temperature change of the heated system and automatically limit the heating temperature. The “PTC” characteristic, that is, the positive temperature coefficient effect, refers to the characteristic that the resistivity of the material increases with the increase of temperature and increases sharply in a certain temperature range. The self-regulating heating wire can be arbitrarily cut short or extended within a certain range, and multiple cross-overs and overlaps are allowed without the worry of high-temperature hot spots and burnout. Therefore, the advantages of the self-regulating electric heating tape are as follows:
The self-regulating electric heating tape can automatically adjust the output power corresponding to the heated system. Therefore, it will not be burned out due to its own heat generation, but can compensate according to the actual heat required. Therefore, it is a new generation of energy-saving constant-temperature heaters.
It can start quickly at low temperatures, and the temperature is uniform. Each part can automatically adjust according to the temperature change of the heated part.
It is easy to install, simple to maintain, has a high level of automation, and has low operation and maintenance costs.
It is safe and reliable, has a wide range of uses, does not pollute the environment, and has a long service life.
Product Description:
The (GWK) HIGH-temperature series heating cables are applied to the pipelines, container storage tanks, and instrument boxes of industrial enterprises such as petroleum, chemical, steel, and power for heat tracing, heat preservation, anti-freezing, and anti-gelling. It can also be used for anti-freezing and heat preservation of building fire-fighting pipes, de-icing and snow-melting of ramps and roofs, as well as indoor heating in many occasions. The maximum maintenance temperature is 140±10℃. At the aforementioned maximum maintenance temperature, any maintenance temperature can be achieved through thermal design. The self-regulating heating wire is suitable for ordinary areas, explosion-proof areas, and corrosive areas.
