Brand / Type: TEWC (Thermoplastic Electrical Wiring Cable)
Conductor Cross-Section: Examples like 1.0 mm², 1.5 mm², 2.5 mm², 4 mm², 6 mm² (depending on model)
Conductor Material: Copper (stranded or solid)
Insulation Material: PVC (Polyvinyl Chloride) type insulation
Rated Voltage: 450/750 V AC
Temperature Rating: Typically -5 °C to +70 °C
Cable Structure: Multi-core (e.g., 2-core, 3-core, 4-core)
Sheath / Jacket: PVC outer sheath
Installation Type: Fixed wiring for building electrical systems
Standards / Approvals: Compliant with local wiring regulations (e.g., SIRIM/IEC)
Typical Applications: Lighting circuits, power outlets, switch loops, panel wiring
Copper — offers good conductivity and durability.
May be stranded for flexibility (popular choice for installation in conduits).
PVC (Thermoplastic) insulation is used for safety against electrical leakage and mechanical protection.
450/750 V AC — means it is suitable for standard electrical mains wiring in buildings.
Typical useful operating temperature range is -5 to +70 °C under normal conditions.
2-Core: Phase + Neutral (no earth)
3-Core: Phase + Neutral + Earth
4-Core: Often used where an additional conductor or auxiliary line is needed
| Cable Size | Approx. Current Rating |
|---|---|
| 1.0 mm² | ~ 10 A – 12 A |
| 1.5 mm² | ~ 10 A – 16 A |
| 2.5 mm² | ~ 20 A – 24 A |
| 4 mm² | ~ 25 A – 32 A |
| 6 mm² | ~ 32 A – 40 A |
Actual values vary with installation method, ambient temperature, grouping, and local code requirements.
Lighting circuits in residential/commercial buildings
Power outlet circuits (dryer, fridge, microwave — depending on rating)
Switch loops and junction connections
Distribution board internal wiring
Control panel wiring
Thermoplastic PVC insulation for robust electrical and mechanical protection
Flexible copper conductors make installation easier, especially in trunking and conduits
Suitable for indoor fixed wiring where exposure to extreme conditions is limited
Available in multiple colour codes for easier identification of phases, neutral, and earth
| Conductor | Typical Colour |
|---|---|
| Live / Phase (L) | Red / Brown / Black |
| Neutral (N) | Blue / Black |
| Earth (E) | Green/Yellow |
(Colour schemes vary by region and installation practice — always follow local wiring code.)
Always pair TEWC cable with the correct size MCB/RCCB/RCBO breaker based on current rating.
Ensure earth/ground connections are correctly made for safety.
Avoid oversizing load on smaller cables (overheating risk).
Protect cable runs from sharp edges and heat sources.
