Fire Resistant Mineral Insulated Power Cable for Cinema Emergency Electricity, can be used in weaker situation lower than copper melting point (1082°C) which is know as the safest cable. According to China, British and EU standards, It can withstand to severe fire, water and mechanical tests.
As to the cinema condition, when suffered a fire in such a crowded space, mineral insulated power cable can continuously supply electricity to emergency circuit - exit lamp.
Mineral insulated cable possesses a long history of more than one hundred years. It has been developed and put into production in major industrial countries, such as Italy, Canada, Australia, the United States, Russia, Japan etc. China started development and production in the 1960s, began mass production at the end of the 20th century, and put into the national fire design specifications for a large number of domestic applications since the beginning of this century.
Composition of Mineral insulated cable
Mineral insulated cable is a kind of cable which uses annealed copper as conductor, dense magnesium oxide as insulation and annealed copper pipe as sheath. If necessary, it can be squeezed with a layer of plastic outer sheath around the annealed copper sheath. For specially required occasions, a layer of low-smoke halogen free sheath can be applied.
Advantages of Mineral Insulated Cables
Since all the materials of this cable are inorganic, it has some advantages that other cables cannot have, such as, fire prevention, high current carrying capacity, resistance to mechanical damage, non-toxic, non-halogen, explosion-proof, waterproof, corrosion resistance, long life, safety, overload resistance, high temperature resistance, low cost, small bending radius, anti-ant, anti-rat bite, copper sheath used as a protective grounding wire and so on.
