What are the properties of mineral insulated cables?

I. What are the characteristics of mineral insulated cable? Fire characteristics: can be burned through a thousand degrees Celsius for 90min without breakdown. And can pass the international fire-resistant class cable test higher standard test carrying capacity is large: can be reduced by one cross-section, for places where human contact is not allowed, can be reduced by two cross-section. Resistant to mechanical damage: when the cable is subjected to bending, flattening, twisting and other deformations, it will not produce a short circuit and will not affect the electrical performance. Explosion-proof characteristics: seamless copper tubes when the copper sheath used in mineral insulated cables can prevent flammable gases, oil vapor, and flames from entering the interior of the cable. Waterproof characteristics: can be immersed in water for a long time corrosion resistance: copper itself has good corrosion resistance, in the strong acidic and alkaline environmental conditions, only need to add a layer of PVC outer sheath. Long service life: under the ambient temperature of 250℃, it can run for at least 250 years for a long time.
