The mineral insulated cables are a versatile type of electrical cable made up of copper conductors insulated with magnesium oxide powder. The mineral insulated cables are enclosed with a metal jacket and are insulated with magnesium oxide. This normal construction offers great electrical isolation, high-temperature capacity along with the physical protection, especially during harsh environments.
The Mineral Insulated Fire Cable is resistant to fires and is perfect to be used in fire protection systems such as alarm circuits, fire pumps, smoke control systems and so on. Flammable fluids can be handled in process industries through Mineral insulated cables.
The mineral Insulated Fire Cable consist of the given things:
a) Metal Sheath:
The metal sheaths contain different metals that may include stainless steel (304, 310, 316, 321) or Inconel® 600. In extreme situations, a sheath can be built for withstanding a temperature of up to 1150°C (2102°F).
b)Conductor wire:
The conductors can be constructed from different types of materials, the usual ones are – copper, alloys, nickel, Constantin, nickel-plated copper etc. The conductors' number may differ from 1 -6 and even more just by depending on their application to be used.
c)Magnesium Oxide
The magnesium oxide is used for isolating the conductors from its external sheath and even from each other. It becomes good material for usage because of its rounded grain structure, dielectric current, chemical inertness and high-temperature capacity.
The MI cable meets circuit integrity (Passive fire protection) and this provides operation of the electrical circuits in fire rage.
What are the benefits of using Mineral insulated cables in the fire protection system?
a) Both the solid fillings and metal sheath present in the mineral insulated cables make them mechanically sturdy and resistant to severe impacts.
b) Mineral insulated cables are resistant to rust. These characteristics make the material perfect to be used in areas where the failure or replacement may be dangerous or almost impossible.
c) Due to the very low flammability rate the mineral insulated cables become ideal for harsh environment usage and high temperature. It is constructed for operability in high temperatures.
d) The MI cables have the capacity for resisting oxidation, the metal sheath cladding the mineral insulated cable allows protection of the thermocouple wires from any oxidation process.
e) As the MI cables have mineral fillings it offers a good non-reactive insulation. It avoids the thermocouple wires from getting close to a few caustic elements (oils, water, solvents) and with each other too.
f) The insulation is constructed in MI cables in such a way that the cables never burn. This feature makes it ideal for those applications where fire rage can become dangerous.
g) The mineral insulated cables have superb vibration resistant features for protecting the mechanical conditions of every internal conductor wire.
h) The MI cables can be drawn down easily to very little diameters by offering quick response time while used in the temperature sensors.
i) They can be formed or bent without causing any short circuit in between the internal wires and sheaths.
k) Can be sealed easily around when utilised as control cables or extension in a very critical environment.
A caution to remember always is – the MI cables must be protected against intrusion of moisture for maintaining high insulation or dielectric resistance attributes
In the fire rage situation, the MI cables have been proven to give around 3 hours of escape time. Usually, the cables have to pass the furnace test, mainly the German standard ISO834-1, test DIN 4102 1000°C 90 minutes. This cabling technology is listed and approved by UL2196. It is an isolated solution that does not contain zinc, polymer. It also does not require any conduit protection.
