This product is suitable for communication In the lines with 50Hz and rated voltage not exceeding 0.6/1kV, they are mostly used in high-rise buildings, subways, stations, airports, power stations, shopping malls and other relatively closed or crowded important buildings and facilities.
Cable structure
conductor
Section Type 1 or type 2 copper conductor
insulation
High temperature resistant and incombustible inorganic mineral insulation material (mica tape /Ceramic silicone rubber belt), wrapped
Filling (selected according to cable specification)
