Havells Multicore Cables

The Invisible Backbone of Bangalore’s Infrastructure

In the rapid urbanization of Karnataka—from the vertical expansion of residential complexes in South Bangalore to the horizontal spread of industrial corridors in Tumkur and Hosur—the integrity of electrical infrastructure has never been more critical. While architects and developers often focus on visible finishes, the safety and longevity of any structure are fundamentally dictated by what lies within the walls: the cabling.

As the premier Authorized Distributor for Havells in Bangalore, Phoenix Technologies has observed a shift in the market. Contractors and homeowners are moving away from generic wiring solutions and embracing engineered safety. We do not merely sell cables; we provide the foundational assurance that homes, offices, and factories across Karnataka require to operate safely for decades to come.

1. What Exactly is a Multicore Flexible Cable?

To the untrained eye, a cable is just a rubber tube. To an engineer, it is a complex assembly of multiple layers, each with a critical function. A Havells Multicore Cable is an assembly of two or more separately insulated electrical conductors, held together by an overall protective sheath.

Here is the breakdown of what is inside a Havells cable:

A. The Conductor (The Heart)

This is the part that carries the electricity.

• Material: Havells uses 99.95% Pure Electrolytic Tough Pitch (ETP) Copper. This purity level is critical because even 0.05% impurities can increase resistance and cause the wire to heat up.
• Flexibility (Class 5): Unlike a "solid" wire which is one thick stick of copper, Havells uses "Class 5" flexible conductors. This means a single 2.5 sq. mm wire is actually made of 50+ hair-thin copper strands bunched together.
• Benefit: This rope-like construction allows the cable to withstand millions of vibrations in a factory machine without the metal snapping (metal fatigue).

B. The Insulation (The Skin)

Each copper bundle is coated in a color-coded PVC layer.

• Material: Havells uses a special Heat Resistant (HR) PVC compound.
• Role: This prevents the electricity from "leaking" out. It is rated to handle 85°C, which is 15°C higher than standard market cables. This buffer is essential during Bangalore’s hot summers or voltage surges.

C. The Sheath (The Armor)

The outer layer that holds everything together.

• Material: ST-3 Grade PVC.
• Role: This is the tough outer skin that protects the inner wires from physical damage—like being stepped on, dragged across concrete, or chewed by pests.

Havells vs. The "Local Market" Wire

Why pay a premium for Havells? As an authorized distributor, we see the failures of cheap cables daily. Here is the technical difference.

Parameter	Havells Multicore Cable	Generic / "Local" Brand	The Real-World Consequence
Copper Quality	99.95% Virgin Electrolytic Copper.	Recycled Scrap Copper.	Scrap copper has impurities. It heats up faster (High $I^2R$ loss), increasing your electricity bill and fire risk.
Conductor Annealing	Online Annealing. Softened uniformly.	Pot Annealing. Uneven softness.	Havells wires don't break when bent sharply. Cheap wires have "hard spots" that snap inside the insulation.
Insulation Centering	Automatic Centering. Copper is perfectly in the middle.	Manual / Poor Centering. Copper is closer to one side.	If the copper is too close to the edge (Thin insulation), a simple scratch can expose the live wire, causing a shock.
Temperature Rating	85°C Operating Temp.	70°C Operating Temp.	Havells can survive a motor overload or a hot day without melting. Cheap insulation becomes brittle and cracks after 2-3 years.
Pest Protection	Anti-Termite & Anti-Rodent.	None.	In Bangalore's independent houses, rats are the #1 cause of short circuits. Havells cables chemically repel them.
Fire Safety	High Oxygen Index (>29%). Self-extinguishing.	Low Oxygen Index. Burns like a wick.	If a fire starts, Havells cables stop it. Cheap cables carry the fire from the kitchen to the bedroom.

Which Cable Do You Need? (By Core Count)

Contractors often ask our team at Phoenix Technologies which cable fits which application. Here is the definitive guide:

2-Core (Red/Black):

Best For: Small appliances (mixers, chargers), decorative lighting, and false ceiling grids where no earth connection is needed.

3-Core (Red/Black/Green):

Best For: Safety Critical Appliances. Refrigerators, washing machines, and iron boxes. The third "Green" wire connects to the earth, preventing electric shocks.

4-Core (Red/Yellow/Blue/Black):

Best For: Industrial Power. Connecting 3-Phase motors, pumps, and central HVAC units in factories (Peenya/Bidadi).

Multi-Core (6 to 61 Cores):

Best For: Automation Control. Carrying signals (not power) between control panels and sensors in CNC machines.

Select the Right Safety Code

Product Variant	Best Application	Key Feature
Life Line Plus (HRFR)	Residential / Commercial	Heat Resistant Flame Retardant. Prevents fire spread.
Life Guard (FR-LSH)	Malls / Hospitals	Low Smoke, Low Halogen. Burns cleanly to ensure visibility during evacuation.
Life Shield (HFFR)	Data Centers / IT Parks	Halogen Free. Releases zero acidic gases, protecting servers from corrosion.

 

Nominal Area (sq. mm)	Current Rating (Amps)*	Max Resistance @ 20°C (Ω/km)	Approx. Outer Dia. (3-Core)
0.5 sq. mm	5 A	39.0 Ω	6.4 mm
0.75 sq. mm	8 A	26.0 Ω	6.8 mm
1.0 sq. mm	12 A	19.5 Ω	7.2 mm
1.5 sq. mm	16 A	13.3 Ω	8.2 mm
2.5 sq. mm	22 A	7.98 Ω	10.1 mm
4.0 sq. mm	29 A	4.95 Ω	11.5 mm
6.0 sq. mm	37 A	3.30 Ω	13.0 mm
