Use this wire size in combination with MICRO sleeve. Very experienced sleevers will also use it with SMALL sleeve, but it's not for the average user, because it requires perfect "length-stretch and fix the sleeving" skills. Do NOT use it with XTC, only use XTC if you bundle 2 or more of these wires into one XTC sleeve. Grey hookup wire is typically used with all of our grey shades and carbon shades, which include grey. It's also perfect to keep the intensity of all medium and light cable sleeving colors at a neutral level, just between the subtle differences which Black or C-White wire create when used as the base for cable sleeving. Stranded 17 AWG hook-up wire Grey, of course 100% tinned copper, no markings and coming as a beautiful large inner diameter ring to prevent spiral shaping as much as technically possible. At an outer diameter of only 2.00 mm, this is a class of its own. Maximized conductor size for lowest resistance, minimized outer diameter: This is the uncompromising MDPC-X 17 AWG hook-up wire Grey, of course 100% made in Germany.   What's better than a high cross-sectional diameter? An even higher one! The bigger the cross-sectional diameter, the lower the electrical resistance. Heating issues at high load? Not anymore! 18 AWG is the standard size used in todays computers. At an outer diameter of only 2.00 mm MDPC-X now brings you the next bigger conductor size of 17 AWG, because we can. The outer diameter of only 2.00 mm allows you to use 17 AWG now in the same way as you used 18 AWG before - ideal for push-in connectors like SATA THROUGH. This wire exceeds 18 AWG in electrical performance while being smaller or the same in outer diameter. Technical Data: This wire comes in rings of 10 meter lengths Tinned copper conductor in PVC insulation according to VDE 0812 -30°C to 80°C PVC insulation, flame resistant according to VDE 0482-332-1-2. Once braided with MDPC-X cable sleeving it is resistant from -58°C to +155°C. Short term peaks of 215°C can then also be handled without structural degradation Constant operating voltage: 900V, Test voltage 2.500V Electrical resistance per kilometer: max 18.5 Ohm Attention: Hook-up wire is a relatively heavy item. It can quickly raise the weight based shipping cost to the next level.
