SJOOW PORTABLE POWER CABLE: 14 gauge 3 conductor SJOOW electric wire (SJOOW: Service, Junior, Oil, and Water Resistant) is made for high power conditions, perfect for industrial, outdoor, commercial use, including welder, machinery, power generator, motor lead, automotive, battery charger. HEAVY DUTY 14/3 SJOOW WIRE: The 300V 14 AWG SJOOW wire contains stranded tinned copper conductors (41 strands 0.254mm copper wire per conductor), which have better anti-oxidation and corrosion resistance than pure copper, thus extending the service life (especially suitable for humid or corrosive environments). High quality conductor (resistant 8.7/KM, 20) provides high capacity for handling higher voltage loads. HIGH QUALITY PVC INSULATION: The operating temperature range is -40 to 90, meeting the requirements of extremely cold or high-temperature environments (such as outdoor construction sites and cold storage warehouses). 0.5mm thick PVC insulation layer + 1.3mm oil-resistant sheath, res
