Single single 10kV power cable with copper shield can wear steel pipe? What will be the impact?
. the first two said two cables, KW is KVV that PVC insulated jacket control cable. . the control cable for industrial and mining enterprises, energy and transportation sector, for the exchange rated voltage 450/750 volts below the control, protection lines and other occasions, the use of PVC insulated, PVC sheathed control cable. . the performance difference: the power cable in the main line of power systems used to transmit and distribute high-power power, control cable from the power system distribution point of electricity directly to a variety of electrical equipment, power equipment, power lines. The rated voltage of the power cable is generally 0.6 / 1kV and above, the control cable is mainly 450 / 750V. The same specifications of the power cable and control cable in the production, the power cable insulation and sheath thickness than the control cable thick.
Do not have to be so troublesome, such a phenomenon even encountered, is the basement of the air defense, similar to the landlord said the phenomenon can be taken as follows: . first with linen live wire and casing blank. . filled with asbestos cement and compaction, the surface concave sleeve 3-4 cm. . with plugging the king (5 yuan / bag) add water and mix well, smear the surface to smooth. . the work is completed, do not hurt the core and the practice proved no leakage within two years.
Cable 2 * NH-KW2 * 1.. the first two said two cables, KW is KVV said PVC insulated jacket control cable,
