Liyond Tulip Contacts for Vacuum Circuit Breaker
Tulip contacts are crucial components in medium- and high-voltage vacuum circuit breakers (VCBs). They are designed to provide a reliable and efficient conductive path to handle the high currents and voltages found in power systems. Their design ensures low resistance and a secure connection within the circuit breaker when it is closed.
Construction and Performance
Liyond's tulip contacts are engineered for robust performance and a long service life. They are widely used in vacuum circuit breakers, MV switchgear, and handcarts, and are built to withstand frequent operations.
-
Materials: The contacts are primarily made from high-purity T2 red copper for excellent electrical conductivity. The body is treated with a thick silver plating to improve conductivity and corrosion resistance. A ring-shaped spring made from non-magnetic stainless steel holds the contacts in place, ensuring uniform pressure and avoiding eddy currents.
-
Manufacturing: The contacts are created by a fine punching process from copper plates. The conventional silver plating thickness is 3μm.
Key Product Parameters and Ordering Information
Liyond's tulip contacts are available in a wide range of specifications. They are suitable for various rated currents including 630A, 1250A, 1600A, 2000A, 3150A, and 4000A. They are also designed for rated voltages of 12kV, 24kV, and 40.5kV.
To ensure the correct product is selected, confirm the following key points:
-
Rated Current: This determines the number of contacts.
-
Fixed Contact Size: The dimensions of the fixed contact.
-
Contact Arm Groove Size: The size of the groove on the contact arm.
-
Silver-Plated Thickness: The conventional thickness is 3μm.
