Cords designed for outdoor use in low temperatures are constructed with materials that resist cracking and remain flexible even when significantly cold. These typically include heavy-duty, thermoplastic elastomer jackets and insulation. An example would be a 12-gauge cord rated for -40F (-40C) used to power a block heater.
Durable, low-temperature-resistant power cables are essential for maintaining the functionality of critical equipment and appliances during winter. Using standard cords in frigid conditions can lead to insulation damage, reduced power delivery, and potential safety hazards. The development of these specialized cords stemmed from the need for reliable power in extreme environments, supporting everything from industrial operations in arctic climates to residential needs like powering heated blankets or outdoor holiday decorations.
