If the insulation resistance of the air electric heater drops to a low level due to long-term placement

SRY6-4, 5, 6, 7 types, the diameter of the electric heater protective sleeve is 108mm, the wall thickness is 4mm seamless steel pipe, the heating core uses three electric heating tubes as a heating element, and the wiring device cover is protected by stainless steel, which can effectively protect the safety of the wiring device.

1. The dimension "B" in the external dimension diagram must be completely immersed in oil to avoid burning the components. The heated oil should be non corrosive.

4. Components should be stored in a dry place. If the insulation resistance drops below 1 megaohm due to long-term storage, they can be dried in an oven at around 200 degree for several hours (or the components can be powered on at low voltage for several hours), and the insulation resistance can be restored by the electric heater.

The device utilizes the excellent insulation performance and high temperature resistance of mica sheets. It uses mica sheets as the skeleton and insulation layer, supplemented by galvanized or stainless steel sheets for support and protection. It can be made into various types of heating devices, such as sheet, cylindrical, conical, cylindrical, and circular. Normal surface load is 2.5-3W and can withstand temperatures of 500 degree .

Cast aluminum and cast copper electric heating plates can be divided into die casting and casting casting. In situations with multiple specifications and sizes, casting technology is generally used. During casting production, high-purity aluminum and copper blocks are used. They are transformed from solid to liquid by a high-temperature furnace, and then injected into a mold with installed heating tubes. After cooling and forming, they are precision processed and produced.

1. Widely used in household appliances, such as rice cookers, microwaves, electronic disinfection cabinets, hair dryers, electric irons, etc;

2. It is widely used as a heating component on various machinery and equipment, such as laminating machines, copiers, printers, transmission lines. It is also used in various industrial and agricultural heating scenarios, such as mold heating, plastic machinery, and other heating and drying devices.
