Liyond Vacuum Circuit Breaker Contacts Category

Liyond offers a comprehensive range of vacuum circuit breaker contacts, which are essential components for ensuring a reliable and efficient conductive path within medium and high-voltage power systems. These circuit breaker contacts are designed for robust performance and a long service life. The product line includes tulip contacts, fixed contacts, and contact arms, each engineered to meet specific operational demands.

Features and Design

  • Tulip Contacts: These contacts are made from high-purity T2 red copper to ensure excellent electrical conductivity and are plated with a thick silver layer for enhanced corrosion resistance. A ring-shaped spring made from non-magnetic stainless steel provides uniform pressure, preventing eddy currents and ensuring a secure connection. The contacts are produced using a fine punching process.

  • Fixed Contacts: Positioned to remain stationary during operation, fixed contacts are typically installed in the switch cabinet's contact box. They are manufactured from either copper or a copper-aluminum alloy to suit various application requirements.

  • Contact Arms: These components function as auxiliary parts in switchgear and handcart applications. They are primarily made from copper or copper-aluminum, providing reliable performance. Less commonly, they can also be made from aluminum.

Ordering Information

To ensure you receive the correct contacts for your vacuum circuit breaker, please provide the following details:

  • Rated Current: This is a crucial factor, as it determines the number of contact "fingers" required. Liyond's tulip contacts are available for rated currents of 630A, 1250A, 1600A, 2000A, 3150A, and 4000A.

  • Rated Voltage: Specify the rated voltage of your system from the available options: 12kV, 24kV, and 40.5kV.

  • Product Specifications:

    • Fixed Contact: Specify the required product size, material, rated current, screw hole size, and silver-plated thickness.

    • Contact Arm: Provide details on the product material, rated current, bottom hole diameter, silver-plated thickness, and the groove size and length needed to match the corresponding tulip contact.
