1. Fire prevention
Because all cables are made up of inorganic materials (metal copper and magnesia powder), it does not cause fire, can not burn or fuel. Because the melting point of copper is 1083, and the melting point of Magnesium Oxide is 2800, so the cable can continue to keep power under the fire of copper melting point, it is a real fire protection. Cable。 And it can be tested by BS6387 C, W and Z.

Two, large capacity and waterproof
Because the actual operating temperature of the mineral insulated cable can reach 250 C, IEC60702 specifies that the continuous working temperature of the mineral insulated cable is 105 degrees C, which is considered to the needs of the terminal sealing material and safety. Even so, its carrying capacity is far more than the other cables, because the magnesia powder has a better thermal conductivity than the plastic, so the same is the same. The working temperature of the sample is greater and the flow rate is greater. For a line above 16mm2, a section can be reduced, and two sections can be reduced to places where people are not allowed to contact.
Because the copper sheath used in the mineral insulated cable is a seamless copper tube, the sealing mud used by the terminal is also a high-tech product that can be soaked in the water for a long time, so the water molecules are completely blocked out, which is a real waterproof product.
Three, explosion proof and corrosion resistance
Explosion-proof characteristics: because the copper sheath used in mineral insulated cables is a seamless copper tube, and magnesia powder is tightly compacted, flammable gas, oil vapor, flame can not reach the electrical equipment connected with the cable, so the cable has the explosion-proof characteristics.
Corrosion resistance: because copper has good corrosion resistance, it does not need any additional protection in the normal environment. Under special environmental conditions, such as a strong corrosion to copper, a layer of PVC outer sheath is added outside the cable, so the cable has good corrosion resistance.
