The cast aluminium electrothermal coil is made of tubular electrothermal element as heating body. The element is formed by bending and then cast aluminium into the die to form various products. It can be closely fitted with the heated body, uniform heating, good thermal conductivity, long service life and so on. Cast Aluminum Heating Ring Price This product is currently one of the ideal heaters at home and abroad. According to the user's needs, the thermal insulation layer can be added outside the heater. The thermal efficiency is higher and the electricity consumption can be saved by about 20%. Mainly used for heating plastic machinery, ovens, boilers, pipes and non-corrosive liquids.

It is widely used in plastic machinery, mould, cable machinery, alloy die-casting machine, pipeline, chemical industry, rubber, petroleum and other equipment.

Technical parameters:

1. Conditions of use: ambient temperature - 20 ~60 ~and relative humidity < 80%.

2. Electrical strength: It can be tested by sinusoidal AC withstand voltage of 1500V50HZ. No breakdown occurs when withstanding voltage of 1M1N.

3. Leakage current: <0.5MA.

4. Insulation resistance: > 2M.

5. Grounding resistance: <0.1.

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

7. Temperature Resistance: The surface temperature installed on the machine can be nearly 400 C.

Instructions:

The working voltage shall not exceed 10% of the rated value.

The wiring part is placed outside the heating layer and insulation layer, and the shell should be effectively grounded.

Cast aluminium heating ring should be placed in a dry place. If the insulation resistance is less than 1M due to long-term placement, it can be baked in an oven of about 200 degrees Celsius for 5-6 hours, and then it can return to normal.
