This cable may be used as: 1) overhead cable 2) buried cable 3) in water (fresh water) Digital Kommunikasjon 2002 12 NTNU Department of Telecommunication s Part II Properties of a single pair • Equivalent model of a single pair • Capacitance • Inductance • Skin effect • Resistance • Per unit length model of a pair. Lap length In Compression: The lap length in compression shall be equivalent to the development length in compression computed but not less than 24d. Sometimes a cable may not have a complete break. Use this online nichrome wire calculator to calculate resistance, power, current and voltage of the Nichrome coil by just providing the length, thickness and temperature of the NiCr. Cables in the merchant service vary in length from 100 to 140 fathoms or more ; but as a maritime measure , a cable ' s length is either 120 fathoms ( 720 feet ), or about 100 fathoms ( 600 feet , an approximation to one tenth of a nautical mile ). AWG Stranding. Wire length and coil frequency calculator is an online tool for electrical and electronic circuits to measure the Wire Length required and the Coil frequency based on the values of coil frequency in khz and wire length in feet respectively.
