Product Introduction
Product Description
Manganese Copper Stamping Parts, including Primary Wire Manganin Shunt, Prepayment Meter Shunt, Manganin Shunt Resistor, and Copper Manganin Shunt, are essential components in the field of electrical metering and circuitry. These parts are specifically designed to handle and measure electrical currents accurately. They are fabricated using a combination of manganese and copper, which imparts unique electrical properties crucial for their intended applications. The precise stamping process gives them the required shape and form to fit into various electrical devices and systems.
Product Parameters
Resistance value
Ranging from a few milliohms to several ohms, depending on the specific application. For example, a Primary Wire Manganin Shunt used in a high-current measurement circuit might have a very low resistance, typically in the range of 0.01 to 0.1 ohms, to minimize power loss and accurately measure large currents.
Temperature coefficient
Manganese copper has a relatively low and stable temperature coefficient, usually around ± 20 ppm/°C. This ensures that the resistance of the shunt remains relatively constant over a wide temperature range, which is vital for accurate current measurement in different environmental conditions.
Dimensions
Length can vary from a few centimeters to several tens of centimeters, and width and thickness are carefully designed to meet the space and current-carrying requirements. A Prepayment Meter Shunt might have a length of around 5 to 10 centimeters, a width of 1 to 3 centimeters, and a thickness of 0.5 to 2 millimeters.
Reasons for Choosing Magnetic Holding Manganese Copper Shunt
High accuracy
The stable resistance of manganese copper alloy allows for extremely accurate current measurement. It provides a reliable reference for electrical metering, ensuring that the energy consumption is measured precisely in prepayment meters and other electrical measuring devices.
Low-temperature drift
The minimal change in resistance with temperature variation makes it suitable for applications where the operating environment temperature can fluctuate. It helps maintain the accuracy of the current measurement over time and in different thermal conditions.
Good long-term stability
Manganese copper shunts have excellent long-term stability, meaning they can maintain their electrical properties for an extended period. This reduces the need for frequent calibration and replacement, resulting in lower maintenance costs and increased reliability of the overall electrical system.
Product Production Equipment and Workshop
| Precision stamping presses | These presses are computer-controlled and have high tonnage capabilities to ensure accurate and repeatable stamping operations. They can handle different thicknesses of manganese copper sheets and produce shunts with tight tolerances. |
| Die-making equipment | Advanced CAD/CAM software and machining tools are used to create custom dies. These dies are made with high precision to achieve the complex shapes and features required for the shunts. |
| Annealing furnaces | Specialized furnaces with precise temperature control are available for the annealing process. The atmosphere within the furnace can be controlled to prevent oxidation and ensure the desired metallurgical changes in the material. |
| Clean and controlled workshop environment | The production takes place in a clean and well-ventilated workshop. Dust and other contaminants are minimized to prevent any surface contamination of the shunts during production. |
