What Are The Differences Between SPT-1 And SPT-2 Power Cords?

What is an SPT power cord?

It's a portable cable suitable for household appliances and light applications. SPT flexible power cords are also called lamp cords, light ropes, or SPT cables. Due to their wide range of uses, they are easily identifiable and can be found in most homes, such as radios, fans, clocks, extension cords, etc. They are also commonly used for Christmas holiday lights.

The SPT series of power cords mainly comes in three sizes: SPT-1, SPT-2, and SPT-3. SPT-1 and SPT-2 are two common sizes when choosing UL-certified power cords for household appliances, medical equipment, or industrial equipment, but they often confuse consumers. This article focuses on SPT-1 and SPT-2. Because both comply with the UL62 standard, they are widely used in the North American market, but their structural differences determine their different application scenarios. As a professional cable manufacturer, Guangdong Zhengfeng Wire & Cable Technology Co., Ltd. specializes in producing SPT-1 and SPT-2 power cords. All products are UL/CUL certified, ensuring safety and reliability. We provide customized cable application solutions for our customers.

The main difference between SPT-1 and SPT-2 wires lies in the insulation thickness: SPT-2 has a thicker insulation layer than SPT-1, making it more durable and weather-resistant. SPT-1 is more flexible and better suited for temporary or indoor use, while SPT-2, although stiffer, is better suited for permanent outdoor installations. Both have the same wire gauge (e.g., 18 or 16 AWG) and the same rated current for a given wire gauge, determined by the wire gauge, not the insulation thickness.
