What is a mineral insulation cable. Metal sheath with mineral insulation, or micc abridged, are cable that, Unlike conventional cables, are covered with a metal sheath and isolated with magnesium oxide. They offer better physical protection in difficult environments.
Mineral insulation cable structure
The metal sheath of cable mineral insulation is generally composed of copper, stainless steel and other metals. Insulation materials use magnesium oxide and other mineral materials. copper cable are used for internal conductors.
The metal sheath provides a solid cable support and protection. Magnesium oxide has good electrical insulation and remains stable at high temperature.
Benefits of Metal sheath cable mineral insulation
Resistance to Temperatures ANDlifting
Mineral insulation cable generally use copper as sheaths. Copper has a high melting point of 1083 ° C, While magnesium oxide has a higher melting point of 2852 ° C than copper.
It can operate normally in a high temperature environment. Normal working temperature can reach 250 ℃, which is perfectly suited to the melting, to steel production and other areas.
Resistance to Feu
The structural design of the metal sheath offers good fire resistance. It is not easy to burn in a high temperature environment. Magnesium oxide is a good fireproof material, who doesn’t Product no smoke and can effectively prevent the flame from spreading.
This characteristic is widely used in fire protection systems in buildings and in industrial fire protection systems.
Respect for L’Envirt
The insulation layer of the metal sheath sheath mineral insulation is generally made up of mineral materials. The manufacturing process, production and use does not produce chemicals. It plays a positive role in ecological development.
Resistance to Corrotion
As a precious metal, Copper has good corrosion resistance. When copper is oxidized in copper oxide, He adheres to the surface of the copper and protects the lower layer from the copper against erosion.
Domains of’Application
Mineral insulation cable are widely used in various fields due to their resistance to high temperatures and their high mechanical resistance. They are notably used in the industry sectors, construction, transport, etc.
The Protection design against fire is a very important part of each project. The US National Electrical Safety Code, The German fire prevention code for buildings and the Chinese fire prevention code for the design of buildings all specify the use of mineral insulation cable.
Domain of Construction
Thanks to its good insulation, He can transmit the current stable. It is used for electrical systems in residential buildings, commercial and others, To connect the power lines, Lighting lines, Electrical equipment, etc.
When a fire occurs, The fire extends quickly. It is a threat to the safety of people in the building. Mineral insulation cable has a good fire resistance capacity.
It is not easy to burn, can effectively slow the spread of fire and does not generate smoke or toxic gas. It is widely used in the design of buildings fire protection.
Domaine Industriel
In industrial production processes such as steelworks and power plants, High temperature and high pressure scenarios often occur.
Mineral insulation cable have a continuous operating temperature of 250 degrees Celsius and can continue to provide energy for about three hours to 950 degrees Celsius. An important role in high temperature and high risk scenarios.
This resistance to high temperatures is ideal for these high -temperature operating scenarios. High temperature environments in the merger and metallurgy processes and work equipment in high temperature areas.
All these environments are suitable for mineral insulation cables. A stable and reliable transmission of energy can be maintained.
Furthermore, Some industrial sites have high fire protection requirements. These are for example coal mines, oil fields, etc.
The mineral insulation cable have good fire resistance, This makes it possible to slow down the spread of fire in the event of a fire and save time for the management of the accident and the emergency services. Equipment and staff safety is thus preserved.
Mineral insulation and cable installation and test
First of all, The cable must be cut to the required length, Taking the wiring into account. The insulation must also be removed after the copper sheath was cut.
The installation must be carried out quickly after cleaning the driver to prevent the water vapor from entering the cable and affects the performance.
Joints should be used after installation to prevent steam and humidity from entering insulation.
When the cable crosses the dilation or settlement joints of the building, A exploder should be installed, that is to say to give the cable an S form to solve the problem of the dilation and the contraction of the cable.
The Copper Gaine Gaine Metal Gaine Mineral Insulation must be put to the ground. The section and connection of the earth wire must also meet the standard requirements, with a extremity put to the ground.
The resistance of cable junctions should be tested after installation to avoid problems when using subsequent, which would have more serious consequences. It is also necessary to check the tightness of the intermediate joints in order to guarantee the life of the cable.
Once the pose of the cable is finished, Avoid dragging the cable repeatedly. Prevent the rupture of the metal sheath and the penetration of the water vapor in the insulating layer. This results in a drop in cable insulation performance.
