95 sq mm Silicone Rubber Insulated Flexible Wire
95 sq mm (≈ 3/0 AWG) silicone wire is a soft, very flexible high-temperature wire used for heavy furnace power, busbar links and transformer connections. Silicone rubber stays elastic from −60°C up to 200°C continuous, and up to 250°C in special constructions with a fiberglass outer layer or SS armour.
Our 95 sq mm construction uses 1330 strands of 0.3 mm copper, bunched to about 12.58 mm diameter, with a 1.8 mm silicone wall and a finished outer diameter of about 16.2 mm. These values come from our factory datasheet; maximum conductor resistance is 0.206 Ω/km at 20°C.
The fine stranding is what makes silicone wire so flexible. It bends easily around tight panel corners and moving parts, and it does not harden with heat the way PVC does. That is why it is common in ovens, heaters, lighting fixtures, motors and battery or power connections that see heat and movement.
At 95 sq mm we recommend about 352 A as a safe continuous current, with 387 A as the maximum under good cooling. Conductors are available in tinned copper (standard), bare copper, silver-plated copper and nickel-plated copper, in a full range of colours.
Choosing the right size: If your load is lighter, the next smaller size is 70 sq mm Silicone Wire, which is easier to bend and terminate. If the current is near the limit, or the wire runs in a hot bundle, step up to 0.5 sq mm Silicone Wire for extra margin. Under-sizing a high-temperature wire makes it run hotter, which shortens insulation life, so it is better to choose by current and ambient temperature together.
95 sq mm Silicone silicone wire is supplied on coils or drums in red, black, white, yellow, blue, green and other colours, in single core or multicore. For a quote, tell us the conductor, colour, core count, total length and whether you need a fiberglass outer layer or SS armour for higher temperature.
Every batch is made at our Rewari factory and ships with a Material Test Certificate. Use the silicone configurator to pick size, conductor, colour and length and get a technical data sheet, or send us your requirement on WhatsApp.

Frequently asked questions
What is the outer diameter of 95 sq mm silicone wire?
About 16.2 mm with a 1.8 mm silicone wall, per our factory datasheet.
What current can 95 sq mm silicone wire carry?
About 352 A safe continuous and 387 A maximum with good cooling. High ambient or bundling lowers this.
What temperature is silicone wire rated for?
−60°C to 200°C continuous as standard; up to 250°C with a fiberglass outer layer or SS armour.
Is silicone wire better than PVC for heaters?
Yes. PVC softens around 85–105°C, while silicone stays flexible up to 200°C and does not harden with heat.
