rvv2 * 0.5 rvv2 * 1.0 rvv2 * 1.5 rvv2 * 2.5 power supply line details: 
 Soft power cable ZA-RVV, ZRRVV, RVVZ rvv2 * 0.5 rvv2 * 1.0 rvv2 * 1.5 rvv2 * 2.5 
 Soft power cable is suitable for communications bureau (station), and high-rise buildings such as power transmission and distribution system using the flame-retardant flexible cable. Power Cable Standard: YD/T1173-2001 
 Model: ZA-RVV (ZRRVV ZRVVR RVV z) with flame-retardant flexible cable communication power 
 ZA-RVV22 (ZRRVV22 ZRVVR22 RVVZ22) communication tape armored flame retardant power cable software 
 Communication with the flame-retardant flexible cables for power overhead, pipes, indoor cable trench, buried underground. 
 Flame retardant 
 In the specified test conditions, the sample was burned in the fire after dropping the test, flame spread only within the limits, or residual disability flame burning for a limited period of time to self-extinguishing characteristics. 
 Rated voltage 
 Rated voltage cable design and electrical performance tests with the reference voltage. 
 Rated voltage with U0, U, said unit V. 
 U0 - any insulated conductor and \ \ \ \ "to \ \ \ \" (the cable metal sheath or the surrounding medium) rms voltage between. 
 U - multi-core cable or single-core cable system between any two phase conductors of the voltage RMS, 
 When used in communication systems, the cable's rated voltage should be at least equal to the nominal voltage of the cable system. The conditions are suitable for U0 and U-value. 
 When used for DC system, the system's nominal voltage should be less than 1.5 times the rated voltage cable. 
 Note: The system's operating voltage of the system allows for a long time more than 10% of nominal voltage. If the cable's rated voltage at least equal to the nominal voltage of the system, the cable can be 10% higher than the rated voltage, under voltage use. 
 Use features 
 1, the cables of rated voltage: 450/750V, 600/1000V. 
 2, the long-term working temperature of cable conductor: 70 ℃. 
 3, cable laying temperature should not be less than 0 ℃. 
 4, the minimum bending radius: non-sheathed cable: flame retardant is 6 times the cable diameter, armored cable: 20 times the cable diameter.
