Description
GENERAL SCOPE
The flame retardant CVV/AWA (SWA)/FRT cables are designed to restrict the propagation of flames when affected by fire, they are proper used for public facilities…, rated voltage 0,6 /1 kV, fixed wiring.
APPLIED STANDARD
– TCVN 5935-1 / IEC 60502-1
– TCVN 6612 / IEC 60228
– IEC 60332-1,3
– BS 4066-1,3
IDENTIFICATION OF CORES
– By color of insulation or by color stripe:
+ Single core cable: Black.
+ Multi-core cable: Red – yellow – blue – black.
– Or by customer’s requirement.
CONSTRUCTION
TECHNICAL CHARACTERISTICS
– Voltage level U0 / U: 0.6 / 1 kV.
– Test voltage: 3.5 kV (5 minutes).
– Permissible long-term working temperature for conductors is 70°C.
– The maximum allowable temperature of the conductor when short-circuiting for no more than 5 seconds is:
– 140°C, with an area larger than 300mm2.
– 160°C, with a section less than or equal to 300mm2.
– Fire-retardant cable has characteristics of slow fire transmission so it is difficult to catch fire.
– The cable has the ability to turn itself off after removing the fire source.
