Overview
A 1 mm wire price depends on the copper inside, the insulation and the coil length, not the size alone. A 1 mm wire suits lighting and low load points. The fair way to judge the price is to match the metal, the grade and the length before you compare one reel with another.
A 1 mm wire is one of the smallest sizes used in a home. It has a clear job, feeding lights and light circuits where the current stays low. Because it is small, people often grab the cheapest reel, yet even here the copper, the cover and the length all change the electrical wire price you pay.
Knowing what the size means makes the price easy to read. A 1 mm wire is not just a thin wire. It is a conductor of a set size, chosen to carry a set load. For the bigger picture across every size, see what really sets a wire price.
What 1 mm Wire Really Means
The 1 mm is the area of the copper inside, one square millimetre. It is not the width of the wire with its cover on, which is a little larger. That copper area decides how much current the wire can carry and how much metal sits in every metre. A 1 mm wire carries a light load of around eleven amperes, which suits bulbs, fans and switch runs.
What Moves the 1 mm Copper Wire Price
Even at this small size, a few clear things set the 1 mm copper wire price. Reading them off the reel tells you why two look the same but cost differently.
- Copper quality: The purity of the metal. A high purity copper wire conducts better and runs cooler than a cheap, low grade one.
- Insulation grade: The cover around the copper. Plain PVC is the base, while FR and FR-LSH grades add fire safety and a little cost.
- Coil length: The metres on the reel. A longer coil holds more wire, so the total is higher even at the same rate.
- Brand and standard: A trusted brand built to IS 694:2010 carries a quality that a plain wire 1 mm price on its own does not show.
1 mm Wire on a 90 Metre Coil
Wire is sold on a coil, and a common one is ninety metres. A 1 mm wire coil price is the figure for that whole coil, not for a single metre. So the 1 mm wire price 90 mtr you see looks larger than a per metre rate but buys far more wire. Before you compare a 1 mm copper wire price for a 90 metre coil, work out how many metres your job needs, then the coil that fits is the fair buy. A short coil can look cheaper only because it holds less, which is really how coil length changes the total.
Where 1 mm Wire Is Used
A 1 mm wire belongs on light duty circuits. Lighting points, fan connections and switch runs all sit comfortably on it. It is not made for heavy loads, so a geyser or an air conditioner needs a larger size. Using it beyond its light duty is the one mistake to avoid, since an undersized wire runs hot.
1.5 mm Wire vs 1 mm Wire for Home
A common question is which size to use at home. The 1.5 mm wire vs 1 mm wire for home choice comes down to the load. The table makes it simple.
| Point | 1 mm wire | 1.5 mm wire |
|---|---|---|
| Copper area | 1.0 sq mm | 1.5 sq mm |
| Rough current | About 11 A | About 14 A |
| Best for | Lighting and low load points | Lighting and general home wiring |
| Headroom | Tight on busy circuits | A little more to spare |
For pure lighting and small points, a 1 mm wire does the job. For general home wiring with a few more points on a circuit, many homes step up to a 1.5 mm wire for the extra headroom. The right size is the one that matches the load, not simply the cheaper reel.
How to Choose the Right 1 mm Wire
Once the size suits the load, a quick check keeps the choice sound.
- Confirm the copper is high purity, not a low grade strand.
- Pick the insulation grade the space needs, FR or FR-LSH.
- Check the coil length so you know the metres behind the figure.
- Look for a clear standard marking such as IS 694:2010.
Kundan Cab 1 mm Wires and Cables
For a verified option at this size, Kundan Cab lists 1.0 sq mm within its Copper VIR Single Core range. It is a fixed wiring cable built to IS 694 in electrolytic grade annealed copper, offered in coil lengths such as forty five and ninety metres.
This is why length belongs in any price check. Because the Kundan Cab wires state the size and the coil length clearly, a 1 mm option is easy to compare. Fix the copper grade, the insulation and the length you need, then match the product. See the full Kundan Cab range for every size and grade.
FAQs
1. What is a 1 mm wire used for?
A 1 mm wire is used for lighting and low load points such as bulbs, fans and switch runs, where it carries around eleven amperes. Heavier loads need a bigger size. So a 1 mm wire price only makes sense once the wire is matched to a light duty circuit.
2. Why do two 1 mm wires cost differently?
The size is the same but the rest is not. A 1 mm copper wire price changes with the purity of the copper, the insulation grade and the coil length. A reel with good copper and a flame retardant cover costs more than a thin, low grade one. Compare the full specification to see the real value.
3. Does Kundan Cab make a 1 mm wire?
Yes. Kundan Cab lists 1.0 sq mm within its Copper VIR Single Core range, built to IS 694 and offered in a choice of coil lengths. Confirm the product and length you need, then ask a Kundan Cab dealer for the current price.
Key Takeaways
- A 1 mm wire price is set by the copper grade, the insulation and the coil length, not the size alone.
- The 1 mm is a one square millimetre copper area, suited to lighting and low load points.
- On a 90 metre coil, the figure is for the whole coil, so work out the metres your job needs.
- For general home wiring, many homes step up to 1.5 mm for a little more headroom.
- Kundan Cab lists 1.0 sq mm within its Copper VIR range, to IS 694 and in a choice of coil lengths.
