Nickel-plated lines, also known as silver-plated copper wires or silver-plated, is a silicon-free copper wire, and then silver plated with low oxygen copper wires, after brigading machine. Nickel-plated copper wire is divided into nickel-plated soft circades (TRY) and nickel-plated brass wire. Nickel-plated soft circuars are annealed, changing their physical properties to achieve a soft purpose. Nickel plating surface is smooth and continuous, no harmful defects such as silver particles, burrs, mechanical injuries.
Nickel-plated copper wires are made of concentric plating on the copper core, which has excellent corrosion resistance and excellent mechanical properties, and the nickel plating layer can reduce high frequency loss in high frequency applications. We offer a nickel-plated copper wire having a diameter of 0.020 mm to 2.600 mm, and has a variety of insulating paint and self-adhesive.
Features: corrosion resistance, excellent mechanical properties
Conductor resistance (as an example of copper wire)
The calculation formula of the copper wire resistor R of the length L is as follows:
in
R is a conductor resistance, unit: ohm
l is the length of the conductor, unit: rice
ρ is a conductor resistivity (also known than resistance)
A is cross-sectional area, unit: square millimeter
π is constant
D is the wire nominal diameter, unit: mm
Resistivity ρ
The resistivity (also known than the resistor) is a physical quantity of the measurement of the conductor to hinder the current. The lower the resistivity, the easier the charge is used through the conductor. The resistivity of copper is 0.0171 mm2 / s * m, which is one of the conductors of conductive performance, second only to sterling silver.
Conductivity γ
The conductivity or conductivity coefficient is a physical quantity of the physical conductivity of the material, which is the reciprocal of the resistivity. The minimum conductivity of the annealing copper wire is 58 S * m / mm2, which is equivalent to 100% IACS (International Annealing Copper Standard), the actual typical value is 58, 5-59 s * m / mm2.
Resistance temperature coefficient
The wire resistance depends on the ambient temperature, resistance, and temperature of the resistance, and the temperature of the temperature. At temperature T, the calculation formula of the coil resistance or wire resistance is as follows:
in
α is a resistance temperature coefficient
RT is the coil or wire resistance at the temperature T
R20 is a coil or wire resistance at 20 ° C
