Here’s a clear explanation of what KEI 95 Sq.mm 4 Core Flexible FR Multistrand Industrial Cable (a typical “95 sq mm 4 Core FRLS wire”) means and its description:

🧵 Breakdown of the Cable Description

1. 95 Sq.mm (Cross‑Sectional Area)
This refers to the cross‑sectional area of each conductor (in square millimetres).

• A larger area (95 mm²) means the cable can carry higher current with less heating and lower voltage drop, suitable for heavy‑duty power distribution.

2. 4 Core
The cable has four insulated conductors inside a single overall sheath. Typical usage:

• 3 phase power + neutral (common in industrial/commercial power supply).

3. FRLS / FR‑LSH (Flame Retardant, Low Smoke)
This is a type of insulation and outer sheath material with special safety properties:

• Flame Retardant (FR): Resists spread of fire along the cable.
• Low Smoke (LS): Emits much less smoke if it catches fire, improving visibility and reducing inhalation hazards.
• Often called FR‑LSH (Flame Retardant Low Smoke / Halogen‑free in some variants).

That means:
✔ Better fire safety compared with ordinary PVC cables
✔ Safer in enclosed or populated areas (e.g., factories, buildings, tunnels)

4. Conductor Material – Copper
High‑conductivity copper conductors (stranded for flexibility), providing:

• Good electrical conductivity
• Mechanical strength
• Flexibility for installation

Most flexible multicore FRLS cables use tightly twisted copper strands rather than solid wire to make them easier to bend and route.

5. Voltage Rating (usually ~1100 V)
These cables are typically rated for low‑voltage power distribution up to about 1100 V, suitable for industrial/plant and heavy equipment wiring.

6. Insulation & Sheath – FRLS PVC
A specially formulated PVC compound is used to provide the FRLS performance, meeting standards like IS‑694:2010 for safety and quality.

🛠 Typical Applications

This type of cable is generally used for:

• Three‑phase electrical power distribution (motors, panels)
• Industrial machines and plant wiring
• Power feeds in building infrastructure
• Control panel wiring where fire safety is important
  (Made for scenarios where flexibility and fire safety both matter)
