Cables that use the Copper Nickel Wire

CuNi (Copper-Nickel) wire is used in specialized cables that require high resistance, corrosion resistance, and thermal stability. Below are the key cable types that use CuNi wire:

1. Heating Cables

✅ Self-Regulating Heating Cables – CuNi wire provides stable resistance for floor heating, pipeline tracing, and anti-icing systems.
✅ Constant Wattage Heating Cables – Used in industrial heat tracing, such as oil pipelines and chemical processing.

2. Resistance Cables

✅ Precision Resistance Cables – CuNi wires (e.g., CuNi44, CuNi23) provide accurate resistance in measuring instruments and sensor applications.
✅ Load Bank Cables – Used in power testing and load balancing systems.

3. Thermocouple & Sensor Cables

✅ Compensating Cables – CuNi wires are used in thermocouple extension cables (e.g., Type T, Type E) for temperature measurement.
✅ RTD (Resistance Temperature Detector) Cables – CuNi alloy (e.g., CuNi10) is used as sensing wire for precision temperature monitoring.

4. Marine & Corrosion-Resistant Cables

✅ Submarine & Shipboard Cables – CuNi wire is highly resistant to seawater corrosion, used in marine power transmission.
✅ Offshore & Oil Rig Cables – Ideal for harsh environments due to anti-corrosion and high-temperature stability.

5. EMI Shielded & Low-Noise Cables

✅ CuNi Braided Shielding Cables – Used in high-precision electronic cables to reduce electromagnetic interference (EMI).
✅ Medical & Aerospace Cables – CuNi wires offer stability for low-noise signal transmission in medical and avionics applications.
