House wires
Three wires. Three levels of fire safety.
All three are single-core, flexible copper, 1100 V and ISI marked. The difference is how the insulation behaves if something goes wrong.

Shock Free
HRFRHeat-resistant, flame-retardant PVC
Our general-purpose house wire. Heat-resistant PVC carries more current before it softens, and the flame-retardant compound stops a fault from spreading along the run.
Best for · Everyday lighting, fan and socket circuits

Fire Free
FR-LSHFlame-retardant, low smoke & halogen
A self-extinguishing compound with a higher oxygen index. If a fire does start, it gives off far less smoke and acid gas, which keeps escape routes visible.
Best for · Apartments, offices, shops and shared buildings

Home Shield
FRHFFlame-retardant, halogen-free
Halogen-free insulation that releases no corrosive gas when it burns. The safest of the three for bedrooms, hospitals, schools and server rooms.
Best for · Homes with children, hospitals, schools, data rooms

The full range
From the switchboard to the borewell.
One supplier for the wiring in a home, a factory floor or a solar plant.
Fibre optics, explained
Inside an optical fibre cable.
Six layers protect a strand of glass that carries data as light. Scroll to strip one down and see what each layer does.
01/ 06
Outer jacket
- Diameter
- 2 or 3 mm
- Material
- LSZH or PVC
The outer skin takes the knocks: abrasion, moisture and handling during installation. Its colour tells you the fibre type at a glance: yellow for single-mode, orange or aqua for multimode.
02/ 06
Aramid yarn
- Role
- Strength member
- Material
- Aramid fibre
Strong, non-conductive yarn laid along the cable. When the cable is pulled through a duct, the yarn takes the load so the glass inside is never stretched.
03/ 06
Tight buffer
- Diameter
- 900 µm
- Material
- Thermoplastic
A thicker plastic layer bonded around the coated fibre. It makes the fibre easier to handle and terminate, and its colour identifies the fibre in a multi-fibre cable.
04/ 06
Primary coating
- Diameter
- 250 µm
- Material
- UV-cured acrylate
Two layers of acrylate applied while the glass is drawn: a soft inner layer that cushions it against micro-bends and a harder outer layer that protects it. It is stripped off before splicing.
05/ 06
Cladding
- Diameter
- 125 µm
- Material
- Pure silica glass
Glass with a slightly lower refractive index than the core. Light that meets the boundary at a shallow angle reflects back into the core, so the signal stays inside the fibre, even round gentle bends.
06/ 06
Core
- Diameter
- 9 µm
- Material
- Doped silica glass
The light travels here. A single-mode core is so narrow that light follows a single path, which keeps the signal clean over tens of kilometres at 1310 and 1550 nm.
All six layers
One glass strand, five layers of protection.
Only the core and cladding guide the light. Everything outside them keeps that glass straight, dry and free of strain.
Drawn far larger than life. A real core is 9 µm across, less than a hundredth of a millimetre.
Back together
A few millimetres of cable.
Light enough to coil in one hand, and immune to interference from the power cables beside it, because the signal is light, not electricity.
