At Zhejiang Zhongjing Wire & Cable Co., Ltd, we proudly manufacture and supply SPT-2, a robust and flexible Standard Parallel Thermoplastic Cable designed for a wide range of residential and commercial indoor applications. As an upgraded version of SPT-1, SPT-2 features thicker PVC insulation, offering improved durability, better resistance to wear and tear, and enhanced electrical safety, especially in low-voltage wiring systems.
SPT-2 (Service Parallel Thermoplastic – Type 2) consists of two parallel insulated copper conductors and is available in 18 or 16 AWG sizes. Its thicker insulation makes it suitable for slightly higher current loads and more demanding environments, such as wiring for household appliances, kitchen equipment, power tools, and lighting fixtures. This cable provides a practical, long-lasting solution that ensures stable performance and easy installation.

Product Features
Good Insulation and Durability: SPT cables are usually insulated with thermoplastic, often PVC. They have good resistance to UV, water, and weather, and are moderately resistant to oil, acids, and alkalis. SPT - 2 and SPT - 3, in particular, have thicker insulation, which can better withstand wear and tear and harsh environmental conditions.
High Temperature Resistance: It can withstand high temperatures up to 105 °C, ensuring stable performance in high - temperature environments without easily deforming or affecting electrical conductivity.
Excellent Flexibility: With a flat and flexible design, SPT cables are easy to install in tight spaces, which is very convenient for wiring in various complex environments.
Good Electrical Conductivity: Made of pure copper conductors, it can ensure a stable and safe power flow, providing reliable power support for electrical equipment.
Safety Compliance: SPT cables comply with relevant safety regulations, such as UL - listed, which can effectively prevent overheating and short - circuit problems, ensuring the safety of use in residential, commercial, and industrial applications.
Product Application
Indoor and Outdoor Lighting: It is widely used in indoor and outdoor decorative lighting, such as Christmas lights, C7 or C9 LED lights, and is the first - choice cable for holiday lighting. It can also be used for various lamps, including table lamps, floor lamps, and desk lamps.
Small Household Appliances: Suitable for small household appliances with a current of less than 10 amps, such as humidifiers, small fans, and clock radios. It can also be used for some small kitchen appliances, such as toasters, coffee makers, and blenders.
Audio Equipment: In some cases, SPT cables can be used for speakers and radios instead of speaker wires to transmit audio signals.
Extension Cords: It can be used as a light - duty indoor extension cord to meet the power - taking needs of electrical equipment in different locations.
Low - Voltage DIY Projects: Due to its easy - to - use characteristics, SPT cable is very suitable for small - scale low - voltage DIY electrical projects, which is convenient for enthusiasts to carry out various electrical production and modification.
High - Power Equipment: SPT - 3, in particular, because of its thick insulation and large - diameter conductor, is suitable for high - power applications, such as refrigerators and air conditioners.
