11KV power cable(YJV22)

power cable Introduction: The products can be produced according to our factory specification which is equivalent to the standard IEC60502. The factory can also design and manufacture special XLPE cable according to the other standards required by the customers. They not only have excellent electric, mechanical properties, but also have powerful resistance against chemical corrosion, heataging and environmental stress. Their structures are simple. The permissible maximum operating temperature is 90C. It is convenient for using, and they can be laid with no restriction of different elevation.The Rated Voltage(kv): 1st class 0.6/1 1.8/3 3.6/6 6/10 8.7/15 12/20 18/30 21/35 2nd class 1/1 3/3 6/6 8.7/10 12/15 18/20 - 26/35 No of Core and Range of sectional Area (mm2)1 Core 1.5-800 25-800 25-1200 25-1200 35-1200 50-1200 50-1200 50-1200 2 Core 1.5-185 25-185 3 Core 1.5-400 25-400 25-400 25-400 35-400 50-400 50-400 50-400 4 Core 2.5-400 25-400 5 Core 2.5-400 25-400 Conductor : Cu Core Al Core The Type and Main Application (1) YJV YJY YJLV YJLV XLPE insulated, PVC or PE Sheathed Power Cable For laying indoor, tunnel, channel and undergroud, Unable to bear external mechanical force, but bear the traction force during laid (2)YJV22 YJV22 YJLV22 YJV22 XLPE Insulated, Steel Tape Armoured, PVC or PE Sheathed Power Cable For laying indoor, tunnel, channel and undergroud Able to bear external mechanical force, but unable to bear large pulling force (3)YJV32 YJV32 YJLV32 YJLV32 XLPE Insulated, Fine Steel Wire Armoured, PVC or PE Sheathed Power Cable For laying in shaft with large difference of level.
