LAMP CORD

Lamp Cord, often known as SPT (Service Parallel Thermoplastic), is a lightweight, flexible electrical cord for small household appliances and light-duty lamps. It features a distinctive flat, parallel design with two insulated conductors, making it easy to route. Typically rated for 300 volts and available in smaller gauges, it uses thermoplastic (PVC) insulation. Primarily for indoor, dry environments, lamp cord provides a simple and safe way to power portable, low-power devices.

Lamp Cord, also known as SPT (Service Parallel Thermoplastic), is a lightweight, flexible electrical cord. It features a distinctive flat, parallel design with two insulated conductors, making it easy to route. It is primarily used for small household appliances and light-duty lamps in indoor, dry environments.

SPT stands for Service Parallel Thermoplastic. This designation describes the cord's construction, indicating that it has two insulated conductors running parallel to each other, and its insulation is made from thermoplastic material, typically PVC.

Lamp Cord is designed for portable, low-power devices and light-duty applications. Common uses include: - Small household appliances: Radios, clocks, small fans, humidifiers. - Light-duty lamps: Table lamps, floor lamps, pendant lights. - Holiday and decorative lighting: Especially for indoor or temporary outdoor displays.

Lamp Cord is typically rated for 300 volts. This voltage rating makes it suitable for standard household electrical systems and low-power devices.

Lamp Cord is primarily intended for indoor, dry environments. While some light outdoor use might occur with proper protection, it is not designed to withstand harsh outdoor elements like moisture, UV radiation, or extreme temperatures. Outdoor-rated cords have thicker, more robust insulation for such conditions.

SPT-1 and SPT-2 300V Lamp Cord

SPT (Stranded Parallel Thermoplastic) Lamp Cord, often referred to as "zip cord," is a highly flexible 300V cable designed for small household appliances, portable lamps, and consumer electronics. Both SPT-1 and SPT-2 feature stranded copper conductors laid parallel and encased in a durable, easy-to-strip PVC (polyvinyl chloride) insulation. While they share the same voltage rating, the primary difference lies in insulation thickness; SPT-2 has a thicker jacket (approx. 0.045") compared to SPT-1 (approx. 0.030"), providing enhanced heat dissipation and mechanical protection for heavier-duty applications. Engineered for ease of use, these cords are available in various colors to match home decor and are designed for simple termination with standard polarized plugs.

Key Features
  • Parallel Construction: Conductors are laid side-by-side with a "zip" feature between them for effortless separation and termination.
  • Flexible Copper Stranding: Utilizes fine-stranded bare copper to ensure maximum flexibility and resistance to kinking or fatigue.
  • Specialized Insulation: Encased in premium PVC insulation that is resistant to moisture, chemicals, and abrasion.
  • Distinct Thickness Grades: Available in SPT-1 (thinner insulation for light-duty) and SPT-2 (thicker insulation for higher heat resistance).
  • Safety Certifications: Manufactured to meet UL 62 and CSA C22.2 No. 49 standards for flexible cords and internal wiring.
Common Applications
  • Lamp & Light Fixture Wiring: The industry standard for wiring table lamps, floor lamps, and hanging pendant lights.
  • Small Appliance Power: Used as power supply cords for clocks, radios, fans, and other low-wattage household devices.
  • Ornamental Lighting: Ideal for Christmas tree lights, decorative strings, and seasonal indoor displays.
  • Internal Equipment Wiring: Frequently utilized as internal leads for consumer electronics and small motorized units.
  • DIY Home Repairs: A favorite for repairing or extending the reach of existing 300V-rated power cords.
  • Clock & Timer Systems: Commonly used in the manufacturing of wall clocks and digital timing devices.
  • Retail Display Lighting: Perfect for powering low-profile LED or incandescent lighting in retail showcases.
