PVC Sheathed Mineral Insulated Cable Fire Prevention Large Carrying Capacity

Product Features
1. Fire protection
Since the cables are all composed of inorganic substances (metallic copper and magnesium oxide powder), it will not cause fire by itself, and it is impossible to burn or support combustion. Since the melting point of copper is 1083°C, the mineral insulating layer is also melting above 1000°C. Therefore, this kind of cable can continue to maintain power supply in the case of a fire close to the melting point of copper, and it is a real fireproof cable. And can pass BS6387 C, W, Z test.

2. Large carrying capacity and waterproof
Since the actual normal operating temperature of mineral insulated cables can reach 250°C, IEC60702 stipulates that the continuous operating temperature of mineral insulated cables is 105°C, which is considering the needs of terminal sealing materials and safety. Even so, its current carrying capacity is far higher than that of other cables. , because mineral insulation has better thermal conductivity than plastics, so the same working temperature, the carrying capacity is larger. For lines above 16mm2, one section can be reduced, and for places where human contact is not allowed, two sections can be reduced.

3. Explosion-proof and corrosion-resistant
Explosion-proof characteristics: Since mineral insulated cables use metal sheaths as protective layers, flammable gases, oil vapors, and flames cannot reach the electrical equipment connected to the cables, so the cables have explosion-proof characteristics.
Corrosion resistance: Since copper has good corrosion resistance, it does not need any additional protection under normal use environment. Add a layer of PVC outer sheath, so the cable has good corrosion resistance.

4. Resistance to mechanical damage, long life, halogen-free and non-toxic
Resistance to mechanical damage: Since the metal sheath of the cable has certain strength and toughness, the relative position between the core wires and between the core wires and the sheath remains unchanged when the cable is subjected to deformation such as bending, flattening, and torsion. There will be no short circuit and no impact on electrical performance.
Long service life: Since the materials used in the cable are all inorganic materials, they will not age. Its service life can be calculated according to the rate of oxidation and corrosion of the copper sheath. According to the data, it takes 257 years for the sheath to oxidize 0.25mm at an ambient temperature of 250°C, while the thickness of the sheath of mineral insulated cables is generally between 0.34-1.05, and the operating temperature is lower than 250°C, so the cable has Features of long life.
Halogen-free and non-toxic: Since the cables are all composed of inorganic substances (metal copper and mineral insulating layer), even if they are burned at a high temperature of 1000°C, they will not produce smoke, halogen and toxic gases. It is truly halogen-free and non-toxic cable.

Five, overload resistance, copper sheath can be used as grounding wire
Overload resistance: Since the melting point of copper is 1083°C and the mineral insulating layer is also above 1000°C, compared with ordinary plastic cables, the carrying capacity of mineral insulated cables can be increased by a section level, and at the same time, it can withstand considerable overload. The capacity can reach more than 10 times the normal carrying capacity.
The copper sheath can be used as a grounding wire: for mineral insulated cables, due to the continuity and extremely low grounding resistance of the copper sheath, it can be used as a grounding wire and does not require an independent grounding wire.
