Frequently asked questions
How cold can Polar Wire wire actually go?
Arctic Ultraflex Blue and Arctic Superflex Blue are both rated to -67°F, which is -55°C. The industrial power cord works from -58°F, which is -50°C. Multi-Listed Flexible Wire is rated from -40°F. Diesel locomotive cable is rated -40°F to 194°F (-40°C to 90°C) wet or dry.
Is it oil resistant?
The TPE insulation on Arctic Ultraflex Blue resists saltwater, oil, gasoline and most acids and chemicals. Arctic Superflex Blue uses insulation that resists oil and gas, acids, chemicals, salt water and sunlight. Diesel locomotive cable puts a heavy duty CPE jacket over EP insulation, which resists oils, acids, alkalies, heat and flame, and is sunlight resistant and flame tested to FT-4 and VW-1.
What do you have for a drilling rig feeder?
Diesel locomotive cable, which is listed for oil and gas drilling rigs. It runs 10 AWG to 777.7 MCM at 2000 volts as UL RHH/RHW-2, on stranded tinned annealed copper per AAR 589, and it is cable tray rated at 1/0 and larger. It is quoted rather than sold through the online store, so send the size, the length and whether you want it on a reel or cut and terminated.
