1. First, check whether the power supply voltage at the use site is consistent with the rated voltage of the product. If it is different, it should be equipped with the same power supply voltage as the rated voltage of the product.
2. In order to ensure stability, remember that the shell of the electrical equipment must be reliably grounded.
3. When the electric heater product is used for more than three months, it should be energized intermittently to dry by itself under permitted conditions, heating for ten minutes, power failure for half an hour, and continuous three to four times to drain the moisture inside the electric heating element.
4. The electric heater should be protected from moisture and corrosion during storage and stored in a well-ventilated place.
Instructions for use of cast aluminum electric heating plate:
1) The working voltage shall not exceed 10% of the rated value;
2) The wiring part is placed outside the heating layer and insulation layer, and the shell should be effectively grounded;
3) It should be placed in a dry place. If the insulation resistance is lower than 1MΩ due to long-term storage, it can be baked in an oven at about 200 degrees Celsius for 5-6 hours to return to normal
The cast copper electric heater is an electric heater with a tubular electric heating element as the heating element and a copper material as the shell through die-casting. Its operating temperature is generally between 150 and 450 degrees Celsius. It can be widely used in plastic machinery, die, Cable machinery, chemical industry, rubber, petroleum and other equipment. The characteristics of cast copper electric heaters have the advantages of long life, good insulation performance, strong mechanical properties, corrosion resistance, magnetic field resistance, etc. The same size and power, the cost of cast copper is high, but the heat transfer is fast, the life is long, the same size, the same size, cast copper The high power can be about 1.5-2 times the power of cast aluminum. The high use temperature of copper is high, and the use temperature of aluminum is low.
