Introduce the topic by explaining the importance of electrical wires in various applications, then narrow your focus to TPS cable. Mention that tps electrical cable are a common type of cable used in various installations and applications.Want to learn more? Let’s do it together.
What is TPS Cable?
Define ‘TPS Cable,’ explaining that TPS stands for ‘thermoplastic sheathed cable.’ This type of cable is prevalent in Australia and New Zealand, where it’s used for residential and commercial wiring. It’s named for its durable PVC insulation, which offers protection to the copper conductors inside. TPS wires typically have two or three conductors, including an earth wire in the twin and earth cable.The voltage rating of tps electrical cables is 450/750v, so they are also called low voltage cable.
TPS Cable Types & Size
Discuss the different types of thermoplastic-sheathed cable, which are primarily determined by the number of conductors they contain. You could mention that 2 core TPS cables are typically used for basic lighting circuits, while 3 core TPS wires are used for applications requiring an additional conductor, such as power circuits.
In terms of size, thermoplastic sheathed cables use the same measurements as other cables, with the cross-sectional area of the conductor measured in square millimeters (mm²). Common sizes include 4mm2, 6mm2, and 10mm2 tps cable. The size chosen depends on the current carrying capacity required for the specific application.

What is the TPS Cable Temperature Rating?
Let’s delve into the temperature specifications of TPS cables. Ordinarily, TPS electrical cables are designed to operate continuously at temperatures as high as 75°C. The significance of this temperature rating lies in its role in defining the safe operational environments for the cable. When a cable is subjected to temperatures exceeding its specified limit, it can experience accelerated deterioration, which in turn increases the potential for malfunction or, in extreme cases, may even ignite a fire.
Can TPS Wire be Used Outside?
Explain that while TPS cables offer some degree of protection due to their tough plastic sheathing, they are not designed for direct exposure to the elements. If TPS wires are used outside, they should be suitably protected, for example, through the use of conduit or cable trays.
However, it’s best to consult with a qualified electrician or follow local regulations and guidelines to ensure the safe and appropriate use of thermosetting cable for outdoor applications.
Conclusion
Conclude the article by emphasizing the importance of consulting with an electrical professional when selecting and installing TPS cables. Highlight that while TPS wires are versatile and commonly used, they must be chosen correctly to match the application’s specific requirements, including current capacity, temperature, and environmental conditions.
Choosing a professional cable manufacturer is also very necessary. ZW Cable is a professional manufacturer of tps electrical cable, and we will provide high-quality products at reasonable prices. You can contact us if you have any problem in choosing thermoplastic-sheathed cable.
