What excellent electrical properties does silver cadmium oxide have?
Release Time : 2025-01-13
Silver cadmium oxide has excellent electrical conductivity, which is mainly due to the high conductivity of its silver matrix. In the circuit, the silver cadmium oxide contact can effectively transfer current and ensure the stable operation of the circuit. This high conductivity makes silver cadmium oxide perform well in applications that require high current transmission.
Silver cadmium oxide contact material has low and stable contact resistance, which is an important manifestation of its excellent electrical performance. Low contact resistance means less heat is generated during current transmission, thereby improving the efficiency of the circuit. At the same time, stable contact resistance ensures the reliability of the circuit in long-term operation.
Under the action of the arc, a protective film will form on the surface of the silver cadmium oxide contact, which can effectively resist the erosion of the arc, thereby extending the service life of the contact. This excellent anti-electrical wear performance makes the silver cadmium oxide contact perform well in electrical appliances that are frequently switched.
The cadmium oxide in the silver cadmium oxide will decompose under the action of the arc to produce cadmium vapor, which has an effective arc extinguishing effect. When an arc occurs, cadmium vapor can quickly cool the arc, thereby shortening the arc duration and protecting the safety of circuits and equipment.
Silver cadmium oxide contact materials also have good anti-welding properties. Under high current impacts such as short circuits, the contacts are not prone to welding, thus ensuring reliable disconnection of the circuit.
Silver cadmium oxide not only has good electrical conductivity, but also has good thermal conductivity. This helps to quickly conduct away the heat generated by the contacts during operation and prevent the contacts from overheating and damage.
Silver cadmium oxide contact materials have excellent electrical conductivity, contact resistance, electrical wear resistance, arc extinguishing performance, anti-welding performance and thermal conductivity. These excellent electrical properties make silver cadmium oxide a contact material widely used in various electrical appliances.
