Customized Tungsten Copper Contact
1. What's Customized Tungsten Copper Contact?
Customized tungsten copper contact is non-standard contact made from tungsten copper composite according to the structural design and operating requirements of switching equipment. CTIA's customized tungsten copper contacts combine tungsten's high melting point and arc erosion resistance with copper's electrical and thermal conductivity, allowing contacts to conduct current and dissipate heat while withstanding arc exposure.
2. Characteristics of CTIA's Customized Tungsten Copper Contact
(1) Flexible Geometries: Machinable into cup-shaped, hook-shaped, thin-walled tubular, stepped, and other complex custom geometries to match installation spaces and structural needs of diverse equipment.
(2) Arc Erosion Resistance: High melting point of tungsten assists contact in resisting high-temperature electrical arcs during interruption, minimizing burn-off.
(3) Balanced Conductivity and Erosion Resistance: Tungsten-to-copper ratios can be adjusted to meet arc erosion resistance requirements while maintaining suitable electrical and thermal conductivity.
(4) Multi-Material Combinations: Tungsten copper working ends can be joined to copper or copper alloy bases, allowing the working end to resist arc erosion while the base provides electrical conductivity and mechanical strength.
(5) Reliable Joint Strength: Reliable joining processes help reduce stress caused by differences in thermal expansion between tungsten copper and the copper base, lowering the risk of cracking or detachment.
(6) Precision Dimensional Machining: Mounting holes, contact surfaces, steps, and mating features are precisely machined to ensure accurate assembly with other switchgear components.
3. Applications of CTIA's Customized Tungsten Copper Contact
(1) High-Voltage Switchgear: Used in arcing contacts and arc-striking contacts for high-voltage circuit breakers and Gas-Insulated Switchgear (GIS), reducing arc erosion and extending contact service life.
(2) Medium-Voltage Switchgear: Used in arcing contacts for medium-voltage circuit breakers, Ring Main Units (RMU), and gas-insulated cabinets, reducing contact burn-off and lowering replacement frequency.
(3) Vacuum Switchgear: Used in vacuum circuit breakers and vacuum contactors to enhance arc erosion resistance.
(4) Low-Voltage Switchgear: Used in low-voltage switch with specialized erosion-resistance requirements, mitigating arc-induced material loss.
(5) DC Switchgear: Used in Direct Current (DC) circuit breakers and DC contactors to decrease contact burn-off during interruption.
(6) Specialized Switchgear: Used as arc-striking contacts in load switches, disconnectors, and earthing switches, reducing contact loss caused by arc ablation.
4. Specifications of CTIA's Customized Tungsten Copper Contact
