Description :
DC cable - flame-retardant flexible cable for communication power supply is suitable for use in power transmission and distribution systems of communication bureaus (stations) and high-rise buildings.
Standard for flame-retardant flexible cables for communication power supply: YD/T1173-2001
Product model: ZA-RVV (ZRRVV ZRVVR RVVZ) flame retardant flexible cable for communication power supply
ZA-RVV22 (ZRRVV22 ZRVVR22 RVVZ22) Flame retardant steel tape armored flexible cable for communication power supply
ZRYJVR ZRYJVR22 flame retardant flexible cable for communication power supply
Flame retardant flexible cables for communication power supply are used for overhead, pipeline, indoor cable trenches, and underground direct burial.
Flame retardant performance of flame-retardant flexible cables for communication power supply
The flame-retardant flexible cable used for communication power supply has the characteristic that under specified test conditions, the sample is burned, and after removing the test source, the spread of the flame is only within a limited range, and the residual flame or burn can be extinguished on its own within a limited time.
Rated voltage of flame-retardant flexible cables for communication power supply
The rated voltage is the reference voltage used for cable design and electrical performance testing.
The rated voltage is represented by U0 and U, with the unit of V.
U0- the effective voltage value between any insulated conductor and the "ground" (metal sheath or surrounding medium of the cable).
The effective value of the voltage between any two conductors in a multi-core or single core cable system,
When used in communication systems, the rated voltage of the cable should be at least equal to the nominal voltage of the cable system being used. This condition applies to both U0 and U values.
When used in a DC system, the nominal voltage of the system should not exceed 1.5 times the rated voltage of the cable.
Note: The operating voltage of the system is allowed to exceed 10% of the nominal voltage of the system for a long time. If the rated voltage of the cable is at least equal to the nominal voltage of the system, the cable can be used at a working voltage 10% higher than the rated voltage.
