As the temperature drops and heaters turn on, electrical load in Indian homes spikes sharply. Every winter, thousands of households face short circuits, melted wires, or even fire incidents caused by poor wiring and overloaded circuits.
Let’s understand why cold weather quietly raises the risk of electrical fires — and how quality wires like KE Kable’s FRLS range can make all the difference this season.
🧊 1. Why Winter Increases Electrical Fire Risks
Unlike summer, winter puts a constant, long-duration load on your electrical system — geysers, blowers, heaters, irons, immersion rods, etc.
| Appliance | Power Rating (Watts) | Hours/Day (Avg) | Daily Load (kWh) |
|---|---|---|---|
| Room Heater | 2000 W | 8 h | 16 kWh |
| Water Geyser | 1500 W | 2 h | 3 kWh |
| Iron | 1000 W | 1 h | 1 kWh |
| Immersion Rod | 1500 W | 1 h | 1.5 kWh |
| Electric Blanket | 200 W | 8 h | 1.6 kWh |
➡️ Total load: ~23 kWh/day per household in winter — almost 2× summer usage.
Result: Wires overheat, insulation softens, and sparks ignite dust or cloth near sockets.
🔥 2. The Science Behind Overheating
Every wire carries current based on its cross-sectional area (CSA). When current exceeds its rated capacity, it generates I²R heat loss.
| Wire Size (mm²) | Max Load (Amps) | Suitable For | Risk If Overloaded |
|---|---|---|---|
| 0.75 mm² | 6 A | Fans, lights | Melting, spark |
| 1.0 mm² | 10 A | Low loads | Heating |
| 1.5 mm² | 13 A | Lighting circuits | Insulation damage |
| 2.5 mm² | 18 A | Geysers, ACs | Safe for high load |
| 4.0 mm² | 25 A | Main line, heavy load | Minimal risk |
✅ Tip: Always match wire gauge to appliance load.
KE Kable offers pure copper FRLS wires from 0.5 mm² to 16 mm² with BIS compliance.
⚙️ 3. Common Causes of Winter Electrical Fires
- Old wiring — brittle PVC insulation cracks due to temperature changes.
- Loose plug points — poor contact creates arcing and sparks.
- Overloaded extension boards — using multiple heaters on one socket.
- Unbranded low-quality cables — mixed copper/aluminium cores overheat faster.
- Improper earthing — stray current ignites metal parts or floor moisture.
💡 Fun fact: 68% of domestic electrical fires in India start from short-circuits during winter months (source: CEA 2025 report).
🧯 4. FRLS: The Shield Against Fire
FRLS (Flame Retardant Low Smoke) cables are designed to resist ignition and emit minimal smoke.
| Feature | Normal PVC Wire | FRLS Wire (KE Kable) |
|---|---|---|
| Fire Resistance | Melts quickly | Delays ignition |
| Smoke Emission | Dense toxic smoke | Low, non-toxic smoke |
| Flame Spread | Rapid | Self-extinguishing |
| Copper Purity | Often mixed | 99.97% pure copper |
| Life Span | 3–5 years | 10 + years |

🏠 5. Signs Your Home Wiring Isn’t Winter-Ready
- Flickering lights when heater starts
- Burning smell from switchboard
- Warm plug tops or wires
- Circuit breaker tripping frequently
- Old PVC wiring (10 + years)
If you notice any of these, get a qualified electrician to inspect and replace damaged cables with FR/FRLS-certified wires.
⚡ 6. Winter Electrical Safety Checklist
| ✅ Safety Step | Why It Matters | How KE Kable Helps |
|---|---|---|
| Check wire insulation | Prevent short-circuit | FRLS coating prevents melting |
| Avoid daisy-chained extensions | Stops overload | Heavy-duty wires handle load |
| Use ISI-marked cables | Legal safety requirement | All KE Kable products are BIS-certified |
| Ground every heavy appliance | Prevent shock/fire | Low-resistance copper ensures quick grounding |
| Annual maintenance | Detect faults early | KE Kable dealer network offers rewiring advice |
🌡️ 7. Temperature, Resistance, and Copper Conductivity
Resistance in a wire increases with temperature rise.
This means: colder weather → higher current usage → more heat → more resistance → more fire risk.
| Material | Resistivity @ 20°C (Ω·mm²/m) | Change/°C | Result |
|---|---|---|---|
| Copper | 0.0172 | +0.39% | Stable |
| Aluminium | 0.0282 | +0.43% | Heats faster |
⚙️ KE Kable’s use of electrolytic-grade copper ensures minimum resistivity, reducing heating and voltage drop.
💰 8. The Hidden Cost of Cheap Wires
Many local market wires may cost ₹5–₹10 less per meter, but the hidden risks include:
- Frequent tripping or burning sockets
- High electricity loss (up to 7%)
- Fire hazard & appliance damage
- No BIS or FRLS rating
Long-term, premium wire = cheaper overall cost due to efficiency + safety.
| Wire Type | Cost (₹/m) | Expected Life | Safety Rating |
|---|---|---|---|
| Local/Unbranded | ₹15 | 2 yrs | None |
| KE Kable FRLS | ₹28–₹35 | 10 yrs | BIS FRLS certified |
🧠 9. Consumer Awareness: How to Identify Genuine FRLS Cable
- Look for “FRLS” marking on insulation.
- Check ISI / BIS number (IS 694).
- Confirm manufacturer name and batch code.
- Avoid wires that feel light or loosely wound.
- Prefer pure copper over “CCA” (Copper-Clad Aluminium).

🏗️ 10. Builders & Contractors: Winter Wiring Standards
Government BIS & NBC (National Building Code) recommend:
- Use FRLS cable for all domestic & commercial wiring
- Maintain 20% spare load margin
- Copper purity ≥ 99.95%
- Separate circuit for heating devices
✅ KE Kable meets all these specifications for both domestic and industrial applications.
🌍 11. Delhi NCR Case Study — “Short Circuit at a Commercial Building”
In January 2024, a short-circuit at a small office in Noida caused a fire due to old PVC wires and an overloaded heater line.
Post-incident analysis revealed insulation breakdown at 80 °C.
After rewiring with KE Kable FRLS 2.5 mm²,
- current load handling improved by 27%
- power loss reduced by 4.8%
- zero insulation degradation after 1 year.
🔋 12. Copper vs Aluminium — Why Copper Wins in Cold Weather
| Property | Copper | Aluminium |
|---|---|---|
| Conductivity | 100% | 61% |
| Thermal Stability | Excellent | Moderate |
| Flexibility | High | Low |
| Expansion under heat | Low | High |
| Ideal for winters | ✅ Yes | ❌ No |
Therefore, always prefer copper for home wiring — especially in colder regions like Delhi, Himachal, or Uttarakhand.
