A TPS cable is a type of electrical cable that uses thermoplastic material, typically PVC, for its insulation. The term "TPS" stands for Thermoplastic Sheathed Cable, which refers to the outer protective sheath made of thermoplastic material designed to protect the internal conductors. The internal conductors of TPS cables are usually made of copper, although aluminum conductors are also an option in some cases. The insulation is primarily designed to ensure that the electricity flows safely through the conductors without risk of short-circuiting or electrical shock.

2.1 Single-Core TPS Cable
A single-core TPS cable contains only one conductor, typically used for simple electrical circuits where only one live wire is required. The cable consists of:
Single-core TPS cables are commonly used for low-voltage applications, such as:
In single-core cables, the wire configuration typically includes one live wire, and it can be paired with a neutral wire if required, depending on the electrical system. However, the core cable itself only includes one conductor.
2.2 Two-Core TPS Cable
A two-core TPS cable consists of two conductors, which is typically used in circuits that require both live and neutral conductors. In this configuration, the TPS cable contains:
: Each conductor is individually insulated to prevent any risk of short-circuiting.
: As with single-core cables, the two-core TPS cable is covered by an outer PVC sheath to offer mechanical protection.
Two-core TPS cables are commonly used in circuits that don't require an earth (ground) wire. Applications may include:
Single-phase power circuits
The two-core configuration is often suitable for residential electrical wiring systems where a ground or earth connection isn't always necessary.
2.3 Three-Core TPS Cable
A three-core TPS cable contains three conductors: live, neutral, and earth (ground). The three-wire configuration is often used in circuits that require grounding for safety purposes. The three-core TPS cable typically includes:
Each conductor is insulated to ensure safety, and the cable is encased in an outer PVC sheath for added protection. The earth wire in a three-core TPS cable is critical for electrical safety, as it provides a path for the safe dissipation of fault currents, preventing electric shock hazards.
Three-core TPS cables are commonly used in applications that require earthing, such as:
High-power appliances (e.g., ovens, washing machines, etc.)
The inclusion of the earth wire makes the three-core TPS cable more versatile and safe, especially when connecting devices that may be exposed to electrical faults.
2.4 Four-Core TPS Cable
A four-core TPS cable contains four conductors, including two live wires, one neutral wire, and one earth wire. This configuration is typically used in three-phase systems, where more than one live conductor is required. The four-core TPS cable typically consists of:
This configuration is common in industrial, commercial, and larger residential installations where three-phase power is used. The two-phase conductors allow for the transmission of a higher power load, and the inclusion of neutral and earth wires ensures proper grounding and safety.

Flat TPS cables are similar to standard round TPS cables in terms of conductor count, but they are designed to provide a flat, space-saving form factor. Flat TPS cables can have configurations such as:
Flat two-core cables: Similar to round two-core cables, with live and neutral wires.
Flat three-core cables: Including live, neutral, and earth wires for grounding.

Single-core cables are ideal for simple applications where only a single live conductor is required.
Two-core cables are best for circuits that need live and neutral conductors but don't require grounding.
Three-core cables should be used in systems where grounding is necessary, such as for appliances and systems with metal enclosures.
Four-core cables are appropriate for three-phase power systems, typically used in industrial or large-scale commercial installations.
