Explosion Proof

The MI cable is made up of seamless copper sheath,magnesium oxide powder compacted a tightly solid,So it can prevent the steam,gas and blaze into the electrical equipment connected with the cable.So it has the quality of explosion proof.

High Corrosion Resistance

The copper sheath of MI cables has the self-character of high corrosion resistance.Only in any area where would corrode the copper,it must be covered with a PVC outer sheath to prevent the corrosion.

High Temperature Resistance

This cable works normally and continuously at 250℃ high temperature.works in a short time when it is close to 1083℃-the melting point of copper,and magnesia insulation material doesn't change in the nature.This characteristic is suitable to be used in metallurgy Cement and other high temperature environment.

Resistance to Mechanical Impact

Because conductor and metal sheath of the cable have good strength and toughness,and magnesium oxide is highly compacted during Conductor, sheath and insulation constitutes a dense integral.The relative position between cores and between core and sheath keeps constant when suffering bending, wavering, torsion etc. So there is no short-circuit and electric property can not be influenced.

Advantages of MI Cable

Small curve radius,small space required for laying

The mineral-insulated cable is of a compact body.with a minimum curve radius less than or equivalent to 6D (D being the diameter of the cable).Therefore,the installation of the cable is rather easy and doesn't take much space,making it an ideal substitute for bus-ways to be laid in places where small space is required.

NO Toxicity and Halogen-free

This cable totally consists of inorganic materials(copper and magnesia powder),So it doesn't self-ignite,produce smokes or toxic gases when fire breaks out. Therefore.it is a safe and environment.friendly cable in the real sense.

High Overload

Since this cable makes use of magnesia whose melting point is 2800℃, compared with ordinary plastic cables, the current carrying capacity of mineral insulated cable can be raised to a higher sectional level. At the same time, mineral insulated cable is able to endure very great overload.which can be over 10 times larger than normal current-carrying capacity. Mineral insulated cable recovers quickly after over-voltage, and its insulation is not harmed.
