Inorganic Mineral Insulated Cable Mica Tape Wrapped Copper Sheathed Material
The inorganic mineral insulated Cable are made of copper conductor, inorganic mineral synthetic mica tape wrapped insulation with high temperature resistant of1370 °C, metal sheath that used for fire resistant systems. Maintain circuit integrity under fire conditions.
Advantage:
YTTW insulation is made of inorganic materials. When the copper is used for the sheath,the price of the same size,the price of the same size is higher than that of organic material cable.But from the comprehensive economic benefit,the inorganic insulated cables have obvious superiority:
A: The outer sheath of copper sheathed mineral insulated cable can make PED line,four core cables can substitute five core cables,greatly reducing the price difference;
B: without accessories of through tubes and trays,such cables can be directly laid,saving the cost of accessories;
C:The low smoke halogen-free organic insulated cables will still produce low smoke and low toxic during burning.It can’t be compared with the ability of smoke-free non-toxic of inorganic mineral insulated cables.
D: The service life of organic cable is only 1/5 of that of inorganic cables.So we can see that the comprehensive price of inorganic cables would be much cheaper than the organic cables.
