391675-WH005 is a high-voltage hookup wire designed for demanding electrical applications requiring superior insulation and temperature resistance. The wire features a 16 AWG tinned copper conductor (26/30 stranding) with a 0.075-inch nominal silicone rubber insulation wall, providing an overall diameter of 0.210 ± 0.006 inches. It is rated for 30,000 V DC and operates reliably across a temperature range of -40°C to 150°C, with UL certification to AWM Style 3239 standards. The wire exhibits low conductor DC resistance of 4.4 O/1000 ft at 20°C and minimal inductance of 0.09 µH/ft, making it suitable for high-voltage test equipment, aerospace applications, and industrial instrumentation where thermal stability and electrical performance are critical.
