Aerial insulated cable with rated Voltage 0. 6 / 1KV, 10KV or 35KV (aerial branched cable, aerial bundled cable)
Aerial insulated cable with rated Voltage 0.6/1KV, 10KV or 35KV(aerial branched cable, aerial bundled cable)
The products are fit for transmitting line and distributing line of rated voltage 1KV,10Kv and 35KV in street, traveling development area and near tall buildings, wooded tract and construction area. Compared with bare conductor, this product can be laid more closely to save the line gallery, and have less voltage-drop. Above all, the product installation reduces power accidents and protects life safety.
Executive Standard
The products shall comply with the standard GB12527-90 and GB14049-93. And it can also be designed and manufactured according to the standard of BS, VDE and ICEA recommended by International Electro technical Commission as per users requirements.

Operating characteristics
The installation ambient temperature should not below -20
Max. short circuit(time not over 5S) temperature of conductor:
XLPE insulated aerial cable is 250; High density PE insulated aerial cable is 150
Max. continuous working temperature of conductor:
XLPE insulated aerial cable is 90; High density PE insulated aerial cable is 75
The bending radius of cable is recommended as following,
0.6/1KV cable: not less than 6 times of outer diameter.
10KV35KV: not less than 20 times of outer diameter.
When the cable used in AC system, the rated voltage of cable should be at least equal the rated voltage of system. When the cable used in DC system, the rated voltage of cable should be bigger than 1.5 times of the rated voltage of system.
