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
This product is suitable for overhead, pipeline, indoor cable trench, and underground direct burial.
flame retardant performance
Under the specified test conditions, when the sample is burned and the test source is removed, the spread of the flame is only within a limited range, and the residual flame or burn can extinguish on its own within a limited time.
rated voltage
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.
