The direct resistance heating of the heater manufacturer needs to be made of special alloy materials or non-metallic materials to make heating elements. The heating elements generate heat, which is transmitted to the object to be heated through radiation, convection and conduction. Because the heated object and the heating element are divided into two parts, the variety of the heated object is generally not restricted, and the operation is simple.
Arc is the phenomenon of gas discharge between two electrodes. The voltage of the arc is not high but the current is very large. Its strong current is maintained by many ions evaporated on the electrode, so the arc is easily affected by the surrounding magnetic field. When an arc is formed between the electrodes, the temperature of the arc column can reach 3000-6000K, which is suitable for high-temperature smelting of metals. So is the metal electric heater reliable? This is a question that most people who use this product often ask. Because the thin electric heater is a new non-standard product, not too many people understand it. After some simple clarifications to discuss the use of metal electric heating plates:

First of all, the electric heating film electric heating plate is designed according to the electrician and electrical specifications when designing, no matter it is the heating wire or the wiring part, there is a certain creepage interval;
Secondly, the insulation materials used by the electric heating film, whether it is PET, polyimide, silicone rubber, or mica, have a good insulation effect. The tested electrical strength: 1500V/1min5mA, no flashover phenomenon , Insulation resistance: ≥5 MΩ. Therefore, there is no leakage phenomenon;
Third, different environments and different temperatures use different insulation materials. When the customer places an order, the relevant personnel of our company will make a certain evaluation based on the temperature requested by the customer, and then recommend a suitable electric heating film, without worrying about the temperature being too high and burning the insulation layer;
Fourth, the insulation materials used by the electric heating plate during consumption are made through high temperature and high pressure, which ensures that it will not show the heating wire exposed in a certain operating temperature range;
Fifth, when designing the electric heater, our company will design the power according to the temperature. The internal heating wire of the waste heater will adjust its own power according to the temperature. At the same time, a temperature control switch can be installed, which is equivalent to double maintenance;
After the above analysis, the heating plate is safe in use, and its surface heating and temperature average characteristics will be more and more ignorant by many designers and users.
