Products Detail

mineral insulated cable / cable / mine cable (HS1)

  • Business Information:
  • Certification : , ISO9001 certification
  • Made In : China(CN)

Product Feature:

1. Firep Resistant
The MI cable IS made of inorganic materials ( copper and magnesium oxide), it will neither cause fire nor support combustion. It can keep normal operating even in fire close to melting point of copper bacause melting point of copper is 1083 o C and that of magnesium oxide is 2800 o C, and it can pass C, W, Z test of BS6387. So, it is a fire resistant cable in real sense.

2. High Current Rating
According to IEC60702, the MI cable can work continuously under the temperature of 105 o C as the actual operating temperature of MI cable can be up to 250 o C, which also takes terminal sealing material and safety into consideration. Even though, its current rating is far beyond that of other cables because magnesium oxide powder has better heat conductivity than plastic has rapid heat transmission and radiation, therefore it has higher current rating at the same temperature. As for cross section above 16mm2. You can lower one section and you can lower two sections in areas human contact is forbidden.

3. Water Proof
Because continuous and seamless copper tube is adopted as sheath in MI cable and sealing mud used at the terminal is one high-tech product which can be immersed in water for long time, water is kept out completely. Therefore, it is virtually proof.

4. 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.

5. High Corrosion Resistance
The copper sheath of MI cables has the self 耳 Character of high corrosion resistance. Only in any area where would corrode the copper, it must be coverd with a PVC outer sheath to prevent the corrosion.

6. Resistance to Mechanical Impact
Because conductor and metal sheath of the cable have good strengh and insulation constitutes a dense integral. The relative position between cores and 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.

7. 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 busways to be laid in places where small space is required.

8. No Toxicity and Halogen-free The MI cable is madef iorganic(copper and magnesium oxide powder). So it will not emit fume, halogen and toxic gas even during combustion at the temperature of 1000o C. It is virtually no toxicity and halogen-free cable.

9. High Overload
Because copper melting point is 1083o C and magnesium oxide melting point is 2800 o C, current rating of MI cable can be enhanced one section level comparing with general cable with more overload. Its overload capacity can reach over 10 times of normal ratings.

10. Long Service Life
Because MI cable is made up of inorganic material without aging, we can compute its life span according to oxide, etchvelocity of copper tube. It is reported that 0.25mm sheath will take 257 years to oxide etch under the condition of 250 o C. Also, the thickness of MI cable sheath is 0.34-1.05mm and operating temperature is under 250o C, so MI cable has the quality of long service life.

11. Copper Sheath as a Ground Wire
The MI cable is a good ground wire, for continuity and extremely low grounding resistance, and one ground wire can be saved.
