Fiberglass Mica Cable | Fire Survival & High-Temperature Insulated Cable – Manufacturer in India
Harnawa Insulations is one of the most reputed manufacturers of fiberglass mica cables in India, providing fire-resistant electrical cables designed to maintain circuit stability in case of high temperatures and exposure to flames. The unique feature of Harnawa’s mica insulated cables lies in the fact that these cables can be installed in areas where regular PVC, PTFE or silicone insulated cables cannot exist.
Fire alarm circuits, emergency lighting, furnace wiring and high voltage switchgears, whatever may be your requirement of cable, Harnawa’s Fiberglass Mica Cable has got the solution for you.
What is Fiberglass Mica Cable?
Fiberglass mica cable is a high-temperature, fire-resistant cable manufactured through wrapping the conductor with mica tape and further coating it with braided fiberglass. Mica has very good capabilities for surviving fires and is known for its dielectric strength because of which it does not melt, drip, or decompose even when in contact with flames.
The braided fiberglass further increases the mechanical strength, wear resistance, and ability of the cable to withstand vibrations. With the help of both mica and braided fiberglass, the cable is capable of sustaining very high temperatures that can exceed 750°C while continuing to provide insulation against direct flames and arcs.
Key Features & Advantages
- Superb Fire Protection – Mica tape is an insulating material that retains the circuit during the presence of fire and intense heat conditions
- Tolerance To High Temperature Conditions – It does not melt, drip, or degrade in temperatures above 750°C
- High Electrical Breakdown Voltage – Retains its electrical properties under thermal and electrical stress
- Mechanical Properties – The glass fiber jacket ensures protection from abrasions and vibrations due to mechanical stress
- Chemical And Water Resistance – Ensures protection against oil, water, and chemicals
- Class H Fire-Surviving Insulation – Ideal for use in Class H insulation system and fire surviving cables
- Long Durable Periods – Made for use in harsh industrial conditions
Applications of Fiberglass Mica Cable
Fiberglass mica cable is widely used wherever circuit continuity must be guaranteed under fire or extreme heat conditions, including:
- Heating elements, furnace wiring, ovens, and kilns
- Firesurviving circuits and flame zone wiring
- Fire detecting and alarm circuits, and emergency lighting circuits
- High-heat detecting and heating circuits
- Motors, alternators, and high-temperature circuits
- Boilers, burners, and high-temperature heating equipment
- Transformer and high-temperature coil terminations
- Power plants, refineries, and high-voltage switchgears
- Control systems for which fire protection is vital
This makes fiberglass mica cable the preferred solution wherever normal PTFE or silicone wires cannot withstand prolonged heat or flame exposure.
