Comparison of advantages and disadvantages between ceramic heating rings and cast aluminum heating rings!

What are the advantages and disadvantages of ceramic heating rings and cast aluminum heating rings? Today, we will introduce ceramic heating rings and cast aluminum heating rings to you.

1, Comparison of technical parameters between ceramic heating rings and cast aluminum heating rings

Technical parameters of cast aluminum heating ring

1. Usage conditions: ambient temperature -20 ℃~+60 ℃; Relative humidity<80%

2. Electrical strength: Can withstand voltage 1500V50HZ sine AC withstand voltage test, with no breakdown phenomenon in IMN during withstand voltage test

3. Leakage current:<0.5MA

4. Insulation resistance:>2MQ

5. Grounding resistance:<0.10

6. Power deviation value:+5%~-10%

7. Temperature resistance: Installed on the machine, the surface temperature can reach nearly 400 ℃

Technical parameters of ceramic heating coils

1. Power deviation+5% to -10%

2. Electrical strength: No breakdown phenomenon observed during voltage 1500V50Hz sine AC voltage test

3. High temperature resistance: used at 600-800 ℃

4. The power of ceramic strip threading method is 0.5-15 times higher than that of ordinary methods

2, Comparison of advantages between ceramic heating rings and cast aluminum heating rings

Advantages of cast aluminum heating coils:

1. Cast aluminum heaters have long lifespan, good insulation performance, strong mechanical properties, corrosion resistance, and magnetic field resistance

2. The outer surface is equipped with insulation device, and the inner heat dissipation surface is sintered with infrared radiation, which can save 35% of electricity consumption

Advantages of ceramic heating coils:

1. Fast heat transfer, uniform heating, and stable operation

2. The temperature does not leak out, which can save electricity. The outer cover is not too hot to touch by hand, ensuring safe work

3. High mechanical strength, good thermal insulation performance, large contact surface with heated objects, and long service life

4. Easy installation and maintenance, low maintenance costs
