Product Description
Halogen Free Mineral Insulated Cable Copper Core Low Smoke
Mineral Insulated Cable used in Building, industrial, airport, power station, power supply and others
Method of choosing
1. In the following cases, flexible mineral insulated cables with plastic sheaths should be used:
The cable is placed in an environment that corrodes the copper sheath.
The cables are buried directly or laid through pipes.
The cables are laid in non-technical spaces of buildings and have aesthetic requirements. Where there is a fire protection requirement, a halogen-free and low-smoke plastic enclosure should be used.

2. Specification selection
Determine the maximum operating temperature of the cable according to the cable laying environment, reasonably select the corresponding cable current, and determine the cable specifications.
2.1: There are two types of flexible mineral insulated cables according to the cable temperature
Carrying capacity: at 70°C
Ampacity at 105°C
2.2: The current carrying capacity of the selected cable should be in accordance with the normal operating temperature of 70 0 C under the following laying conditions:
Clean lines along walls, brackets, roofs and bridges.
It is routed together with other types of cables in the same bridge, shaft, cable trench, and cable tunnel.
Other places where the temperature of the cable sheath is too high may cause personal injury or equipment damage.
2.3: Place the cables in the bridge, cable trench and the place where the unmanned machine wears the pipe. The current carrying capacity can be selected according to the normal operating temperature 105 0 C
. 2.4: The specifications of flexible mineral insulated cables should be reasonably determined according to the actual length of the line and the length of delivery of the cable.
