HDT Cable - Heavy Duty Thermoplastic

HDT cable, also known as Heavy Duty Thermoplastic Wire, is a type of automotive primary wire. It is made from a stranded bare copper conductor that is rated for 60 volts. This conductor is surrounded by a PVC insulation that allows it to handle a temperature range of -40°C to 80°C. Allied Wire & Cable carries HDT cable in sizes ranging from 4 AWG to 20 AWG. HDT cable can be used in cars, trucks, boats and a variety of other vehicles for applications that require extra resistance to physical elements such as water and abrasion. Allied offers multiple value-added services for HDT cable including custom printing, striping, twisting, dyeing, cutting and stripping.
