4, Technical characteristics:
(1) characteristics of the power temperature
This characteristic is measured under the conditions of the simulation of the pipe heating.  With the increase of the temperature of the heating system, the power decreases linearly with the decrease of the temperature of the heating system, which reflects the ability of the power to adjust the temperature automatically. It should be pointed out that the power of the electric heating is stable state parameter, the influence factors are many, it can not simply use the current multiplied by the voltage to be calculated, different voltage, power, temperature rating curves is different.
(2) maintainning temperature 
using heating trace or a heating system, if the heat is transferred to the system by the heating trace is the same with the heating amount of the system transfered to the surroundings, and the temperature can be maintained at the highest temperature for a rate of temperature product. If control precision, it need thermostat. 
(3) Maximum withstand temperature
the PTC core strip can withstand certain temperature from external heat source. if higher than this temperature, the power of PTC core strip accumulated lower. Therefore, do not exceed the maximum temperature  of PTC core in the long term using.  Using heat insulation isolation method, can withstand over max. temperature in a short time, the length of the time of safety is a major indicator of product quality.
(4) Maximum surface temperature
In a closed container with good insulation, put a enough length of electric heating trace, the highest temperature at the rated voltage is the highest surface temperature of the electric heating. This parameter is very important in the field of flammable or explosive gas. Different voltage, different power, different temperature grade products have different maximum surface temperature.
(5) Service life:
the service life of the electric heating mainly depends on the PTC heating core band in the using of the output power of the attenuation rate, while the insulation layer and the outer sheath should meet the requirements, otherwise it will affect the service life. The service life is usually measured by the power  attenuation rate.
(6) Maximum using length:
the length of the cable can be arbitrarily shortened, but only within the scope of a certain length connecting; in other words shall not exceeds the maximum length of use. The maximum length of use is different from the minimum ambient temperature due to the rated voltage, the power, the cross section of the conductor, and the minimum ambient temperature. If the length of the request is more than the maximum length of the electric heating trace, it should be used to connect the power supply or take special wiring or use special specifications of medium length or long type with hot cable.
(7) product flame retardant characteristic:
flame retardant divided into self extinguishing and non flammable, oxygen index should be greater than or equal to 30. Non combustible and flame retardant is the two concepts, different grade, but  the flame retardant should be green environmental protection flame retardant.
(8) starting current
It refers to the cable at a certain temperature of a heating system instantaneous current when power on, starting current is usually higher than several times more than the stationary current value.

The heating cable is fixed on the steel wire mesh. One-time pouring concrete.
Anze self-regulating heating cable in the snow melting system, heating cable around the right concrete wrapped to ensure good heat conduction.
 Easy maintenance
The circuit can be quickly recovered if the Anze self-regulating heating cable system is damaged (as in the concrete sawing). Only need to repair damaged the cable, after its performance can be restored.
ANZE control temperature and heating cable in the snow melting system, heating cables buried under the concrete. But all the terminals are in the external connection box, easy to control.
Energy saving and high efficiency
Anze self-regulating heating cable melting system unique self regulation performance means each cable issued a moderate heat, and consume minimal power. All Anze self-regulating heating cable snow melting system's terminals are made in the field, and are placed in the control of the external connection box.
Anze self-regulating heating cable is a fusion the polymer and the conductive carbide of the parallel wire copper power bus, and pass CQC certification. In order to prevent the mechanical impact and corrosion, the copper core and the power bus are wrapped in the modified polyolefin shell. Heating cables are buried in concrete, which is very sensitive to the surrounding temperature. The resistance decreases with the temperature, and the electric current increases with the increase of the temperature. On the contrary, the resistance increases with temperature rise, and then reduces the heat output. Self-regulation techniques can be guaranteed at the appropriate time and area in the heating cable to generate heat. Its advantages are obvious: long term reliable performance, simple design, easy installation and maintenance, and reduce energy consumption. The heat generated at each point of the heating cable depends on the ambient temperature. Even though there is a phenomenon of overlapping under the concrete, it can avoid the phenomenon of overheating. Temperature control device with temperature limit is also a surplus.
Anze self-regulating heating cable snow melting system without complex nodes, thus avoiding in concrete pavement thermal expansion and contraction damaged. At the same time, the system can avoid the heat of the fluid system, the heat is not uneven, corrosion, leakage, node freeze and other issues. Simple installation, more cost advantages. The whole process is simplified as "laying, fixing, pouring".
Anze self-regulating heating cable can be cut into a suitable length in the scene, and the spacing of the 30mm is a long distance. We do not need to set the length, shape and size in advance. Nor will it be the result of a temporary change to the design to produce a delay in order to avoid the loss.
