Tungsten Copper Conductive Rod
1. What's Tungsten Copper Conductive Rod?
Tungsten copper conductive rod is an electrical component used in electrical equipment, particularly switching devices that require both electrical conductivity and resistance to arc erosion. CTIA's tungsten copper conductive rod features either a tungsten copper material structure or a composite structure combining tungsten copper contact with copper rod body. The tungsten copper end primarily withstands arc erosion and contact wear, while the copper rod body carries electrical current. The combination balances arc resistance at the contact end with electrical conductivity along the rod body.
2. Characteristics of CTIA's Tungsten Copper Conductive Rod
(1) Balanced Conductivity and Arc Resistance: Copper rod body carries electrical current, while tungsten copper contact end primarily withstands arc erosion and contact wear. The composite structure combines the properties of both materials to meet the different conductivity and arc resistance requirements of switching devices.
(2) Resistance to Arc Erosion: Tungsten copper offers good resistance to arc erosion, making it suitable for operating conditions involving repeated contact opening and closing and frequent arc exposure. Performance depends on tungsten-to-copper ratio, material quality, and arc conditions.
(3) Good Electrical Conductivity: Copper rod body offers high electrical conductivity, helping reduce rod resistance and power losses during current transmission. Temperature rise across the entire rod also depends on current, rod cross-section, connection quality, and heat dissipation.
(4) Reliable Joint Design: The connection between tungsten copper contact and copper rod must allow efficient transfer of electrical current and heat. Poor connections may increase contact resistance and localized heating, so the joining method and connection quality are important to overall performance.
(5) Customizable Structural Design: Contact dimensions, rod diameter, overall length, and connection type must match equipment requirements. CTIA can customize product dimensions and structural configurations according to installation requirements and operating conditions.
3. Applications of CTIA's Tungsten Copper Conductive Rod
(1) High- and Medium-Voltage Switching Equipment: Used in selected circuit breakers and load switches as part of conductive contact or arcing contact assemblies. The tungsten copper end provides resistance to arc erosion, while the copper rod body conducts current. The specific design depends on switch type and contact configuration.
(2) Electrical Discharge Machining (EDM): Used in selected rod-shaped electrodes or electrode extension components where electrical conductivity, heat resistance, and electrode wear are important considerations. Material selection depends on the machining method, workpiece material, and electrode dimensions.
(3) Resistance Welding Equipment: Used in welding electrodes or conductive components. Material selection depends on welding current, operating temperature, contact pressure, and electrode wear. The suitability of a tungsten copper conductive rod depends on the electrode structure and operating conditions.
