The lightly burned magnesium powder itself does not burn at all, and can run continuously for a long time at 250 ℃. It can also maintain normal operation for 30 minutes at a limit of 1000 ℃ without causing a fire source. Even in the presence of flame barbecue and light burning of magnesium powder, as long as the flame temperature is lower than the melting point temperature of copper, the cable can still be used without replacement after the flame is eliminated. It will not produce toxic smoke and gas when grilled by flames. Desulfurized magnesium oxide
2. Strong overload protection capability
When the circuit is overloaded, as long as the heating does not reach the melting point temperature of copper, the cable will not be damaged. Even if the breakdown occurs instantly, the crystals at the breakdown point will not form carbides. After the overload is eliminated, the performance of the cable will not change and can still be used normally.
3. High working temperature
Due to the melting point temperature of the edge layer crystals being much higher than that of copper, the long-term normal operating temperature of the cable can reach 250 ℃, and it can continue to operate normally in the short term at a melting point temperature close to 1083 ℃ of copper.
4. Good anti-corrosion and explosion-proof performance
Due to the use of seamless copper tubes as sheaths, lightly burned magnesium powder has the properties of waterproofing, moisture, oil, and some chemical substances. Copper tubes have considerable mechanical strength and therefore have good explosion-proof performance.
5. Long service life
Magnesium oxide cables are composed of inorganic materials, so there is no edge aging, and their service life can reach more than three times that of ordinary cables.
