Are metal film heaters safe?
Are metal film heaters safe? This is a question frequently asked by most people who use this product. Because the thin heating element is a new non-standard product, not many people know it. We use some simple instructions to explain how the metal heating element be safe in use.
First of all, the electric heating film heating sheet is designed in accordance with the electrician and electrical standards when designing, whether it is the heating wire or the wiring part, there is a certain creepage distance;
Secondly, the insulating material used in the heating plate, whether it is PET, polyimide, silicon rubber, or mica, has a good insulating effect. The electrical strength is tested: 1500V/1min5mA, no flashover phenomenon, Insulation resistance: ≥5 MΩ. Therefore, there is no leakage phenomenon;
Third, different environments and different temperatures use different insulating materials. When the customer places an order, the relevant personnel of our company will make a certain evaluation according to the customer's required temperature, and then recommend a suitable electric heating film, without worrying about the temperature being too high and burning the insulating layer;
Fourth, the insulating materials used in the production of the heating plate are made of high temperature and high pressure, which ensures that the heating wire will not be exposed within a certain temperature range;
fifth, when the heating plate is designed, Our company will design the power according to the temperature. The heating wire inside the finished heating plate 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 protection;
Through the above analysis, the heating element is safe to use, and its surface heating and uniform temperature characteristics will be more and more unfavorable by many designers and users.
