What Factors affecting conductivity of wires and cables?
Read moreThe temperature of wires and cables The conductivity of metals decreases with the increase of temperature. When the temperature is not very high (close to the melting point) or very low (close to the absolute zero), the resistivity and temperature show the following linear relationship: ρ=ρ0[1+α(T-T0)]. Impurities in wire and cable materials […]
