The SCS - 18 is an 18 gauge, 19 strand single-lead. Each strand is made of very high grade Matched Crystal (MC) OFC covered with a dense and very pure silver coating. The resistance of this wire is: 17.8 Ohm/km. The total metal cross-section area is: 0.97 mm². The external diameter is: 1.82 mm. The insulation is made of PTFE. The diameter is too small to make a clear type printing on this wire. The main application area of this wire is internal interconnect wiring in pre and power amplifiers. Four times SCS - 18 twisted together (with clockwise conductor wiring +-+- = starquad) makes a very fine interconnect. The insulation voltage rating is 600 Volt RMS and the actual test voltage is 3500 Volt RMS. The SCS - 18 is available in 9 colours: black, brown, red, orange, yellow, green, blue, grey and white.
