The copper sheath used for mineral insulated cables is a seamless copper tube

1.Fire prevention

Since the cables are all composed of inorganic substances (metal copper and magnesia powder), they do not cause fires themselves, and it is impossible to burn or support combustion. Since the melting point of copper is 1083 ° C and the melting point of magnesium oxide is 2800 ° C, the cable It is a true fireproof cable that can continue to supply power in the event of a fire close to the melting point of copper. And can pass the BS6387 C, W, Z test.

2.The current carrying capacity is large, waterproof

Since the actual normal use temperature of mineral insulated cable can reach 250 °C, IEC60702 stipulates that the continuous working temperature of mineral insulated cable is 105 °C, which takes into account the need of terminal sealing material and safety. Even so, its current carrying capacity far exceeds other cables. Because magnesium oxide powder has a better thermal conductivity than plastic, the same working temperature and larger current carrying capacity. For lines above 16mm2, one section can be lowered, and two sections can be lowered where no one is allowed to touch. Because the copper sheath used in the mineral insulated cable is a seamless copper tube, the sealing mud used in the terminal connection is a high-tech product that can be immersed in water for a long time, so the water molecules are completely blocked, which is a true meaning. Waterproof products.

3. Explosion-proof, anti-corrosion and explosion-proof characteristics: Because the copper sheath used in the mineral insulated cable is a seamless copper tube, and the magnesium oxide powder is compacted, the flammable gas, oil vapor and flame cannot reach the electrical equipment connected with the cable. Equipment, so the cable is explosion proof. Corrosion resistance: Because copper has good corrosion resistance, it does not require any additional protection under normal environmental conditions. Under special environmental conditions, such as the environment with strong corrosive effect on copper, the cable is outside. A layer of PVC outer sheath is added, so the cable has good corrosion resistance.
