Specification:18 Gauge 3 conductor wire(Red & Black & Yellow & White). Black PVC Jacket. 50ft/15M. Maximum input voltage: 300V(also can for DC6V/12V/24V). Maximum current: 7.5A. Rated working temperature up to 80/176. Material:PVC+Tinned Copper.Flame retardant:VW-1 and FT1 3 Conductor Tinned Copper Wire:18 awg 3 wire cable have 41 strands of 0.16mm tinned copper wire inside each cable. The tin coating not only enhances the conductivity, but also provides excellent corrosion and oxidation resistance, Compared with ordinary copper wire, it can greatly extend the service life of the power cable. It is also more suitable for soldering PVC Durable Material:The jacket of 3 core extension wire is made of high quality PVC to protect the wire from wear and tear in harsh environments. It has the advantages of flame retardant, high compressive strength, anti-aging, acid and alkali resistance, good corrosion performance, etc. It can be buried directly or exposed to the sun for a long
