Regarding TPI (thermoplastic insulated) cables and TPS (thermoplastic sheathed) cables are you aware of the differences? Although, both cables are classified under the thermoplastic category, they differ in terms of their uses and some particular features.
What does TPI cable stand for?
TPI cable stands for thermoplastic insulated cable, where the insulation usually consists of a single layer of thermoplastic material that surrounds a conductive core. In the design of TPS cables, several individually insulated wires are included. These wires are protected by a common outer sheath, forming the overall structure of the cable. In contrast, TPI cables have a simpler structure. It is also a fundamental difference in construction that we can recognize. TPI materials are meltable and reprocessable, so that damaged structures can be repaired by means of heating and pressurization. Additionally, TPI cables offer environmental advantages as they do not contain any low-toxicity reactive chemicals.
What does TPS mean in cables?
TPS cable, known as thermoplastic-sheathed cable, is a type of cable that utilizes polyvinyl chloride (PVC) as the outer sheath material. The outer jacket encases one or more copper conductors and each conductor is insulated with PVC. We will find the cables in various configurations such as single, double, twin and earth. With regard to its appearance, the most common types sold on the market are usually of a smooth flat profile. There are some special shapes such as in Australia where the outer jacket of the TPS flat cable is grooved.Where installation is needed through narrow openings such as along walls, under floors or through them, flat TPS cables are softer and simpler to conform to the mounting surface when laid, hence taking up less mounting space. For fixed installations in industrial environments, circular TPS cable is used more often.

What is the difference between TPI and TPS wire?
TPI Cable VS TPS Cable: Application
TPI Application focus:
- In the machinery industry, TPI offers excellent mechanical properties and friction resistance.
- TPI has good flame retardancy and low smoke generation rate and strong self-extinguishing properties with an oxygen index of 36-46, which makes it preferable for use in the aerospace industry.
- In electronics and communications, TPI maintains good electrical insulation in harsh environments such as high temperature, high pressure and high humidity.
- Some TPI cables may be designed for high temperature applications, while others may be used for data transmission or low voltage distribution.
TPS Application focus:
- TPS cables are widely used in low-voltage electrical installations, especially in residential and light commercial facilities. They are suitable for general-purpose wiring such as lighting circuits, power circuits and control systems. In commercial environments, TPS cables provide a safe and efficient supply of electricity and are the preferred choice for businesses maintaining a reliable infrastructure.
TPI Cable VS TPS Cable: Performance and Durability
TPI cables are designed with a focus on flexibility and ease of installation. These cables are typically lightweight, making them easy to handle and install in different environments. For instance, during complex cable laying. Vertical cable routing as well as horizontal cable distribution in tall structures and even in big systems requires consideration, including the weight of the cables, heat dissipation and fire risk. Thermoplastic insulation also provides protection against abrasion. While conventional cables may become brittle over time, they can withstand repeated movements and adjustments without damage.
TPS cables are well insulated and provide stable electrical isolation for long periods of time, preventing power loss and the risk of short circuits, even under regular room temperature fluctuations.The tough outer jacket of TPS cables extends their service life by resisting everyday physical wear and tear, such as dragging and squeezing during installation, as well as minor bumps or friction that may be encountered after installation. It can operate efficiently in temperatures up to 75°C. However, it should be noted that TPS cables are not suitable for direct exposure to the elements. When used outdoors, they require additional protection against degradation.
TPI Cable VS TPS Cable: Cost and Availability
TPS cables typically offer a cost-effective solution for a variety of applications. Their cost varies depending on the number of conductors and the specific configuration required for the application. Typically, TPS cables are less expensive than TPI cables.
TPS cables also have a high market share, especially in regions such as Australia. Their use in home and commercial wiring installations has made them a common choice for electricians and contractors alike. TPS cables are available in a variety of configurations so that we can choose the type that best suits our needs. The different conductor configurations and voltage ratings ensure that we can select the right TPS double insulated cable for each specific application.
On the other hand, while TPI cables are also cost-effective, TPI cables are designed for use in more stringent environments or require specialized properties such as higher temperature ratings and better chemical resistance, which may increase material and manufacturing costs.
TPI cables are widely available in the market for a wide range of applications. We can easily find them at hardware stores and electrical supply stores.The universal availability of TPI cables allows for easy sourcing of these cables no matter where the project is located.
Practical Application Example
Let us say that a new residential building is being cabled and wired. In this case, TPS cables are often preferred because their reinforced jackets provide additional safety against cuts and abrasions caused by nearby materials or accidental impacts. On the other hand, in a workshop or laboratory environment, traditional wires may suffer from chemical damage, whereas TPI flexible cables will not, as they have better chemical resistance and flexibility.
