Products Description
Silver contacts in breakers play a crucial role in electrical systems, ensuring reliable and efficient electrical connection. Cold-forming process contacts are used to create these contacts with precision and durability. The electrical silver contact point is the key element that makes contact with the circuit, while leaf spring electrical contacts provide the necessary spring-like action for proper contact and disconnection. Bimetal electronic contacts are designed to handle the mechanical and electrical requirements of the breaker.
Product Parameters
Electrical Conductivity
Silver contacts have high electrical conductivity, with a value of around 6.3 x 10^7 S/m. This high conductivity allows for efficient electrical current flow, reducing energy losses.
Contact Resistance
The Contactor Contacts resistance of silver contacts is low, typically around 0.0001 - 0.001 Ω. This low resistance ensures stable electrical performance and minimal power dissipation.
Mechanical strength
The bimetal contacts have a high mechanical strength, with a tensile strength of around 300 - 400 MPa. This allows them to withstand the mechanical forces during operation.
Temperature range
Silver Contact Points can operate in a wide temperature range, from - 40°C to 120°C. This adaptability makes them suitable for various electrical applications.
Moving contact production equipment
| Cold forming machines | Cold-forming machines are used to shape the contacts using the cold-forming process. These machines are capable of producing high-precision contacts with consistent quality. The cold-forming process allows for the creation of complex shapes and structures. |
| Electrical discharge machining equipment | EDM equipment is used to cut and shape the Dry Contactor Electrical Silver Contacts using electrical discharge. This process is highly precise and can be used to create complex shapes and structures. EDM equipment is also used to remove any excess material from the silver contact in circuit breakers. |
| Assembly equipment | Assembly equipment is used to assemble the moving contacts onto the breaker. This includes the use of mechanical tools and fixtures to ensure proper alignment and connection. The assembly process is carefully controlled to ensure the quality and reliability of the contacts. |
| Testing equipment | Testing equipment is used to test the electrical properties of the contacts. This includes the measurement of electrical conductivity, contact resistance, and other electrical parameters. Testing equipment is also used to verify the mechanical properties of the Cold Headed Electrical Contacts, such as the tensile strength and hardness. |
