Home >> Products >>Copper (Aluminum) -cored power cable with sheet iron armored in PVC insulation & PVC (PE) sheath

Standards:

The cable is manufactured according to GB12706-2002 national standard or international electrical committee standard of IEC502-1994
Type: VV22---Copper-cored power cable with armored in PVC insulation & PVC sheath
VLY22---Aluminum-cored power cable witharmored in PVC insulation & PVC sheath
VV23---Copper-cored power cable with armored in PVC insulation & PE sheath
VLY23---Aluminum-cored power cable with armored in PVC insulation & PE sheath
Use: The cables can be fixedly laid in the places where cables can be protected from much strong extraneous mechanical force to a certain degree, such as indoor, aerial, cable conduit tunnel or direct burying for power transmission and distribution line project in rated A/C UO/U at 0.6/1KV and below.
Using characteristics: 1.The temperature of cable laying in the air should not be less than 0<span class="sup">o</span>C,and the bending radius should not be less than 10 times the outer diameter of the cables <br>
2.Long-term working temperature for cable conductor should not exceed 70<span class="sup">o</span>C<br>
3.when there is any short circuit occurring (the lasting time not exceeds 5s),the maximum temperature of the cable should not exceed 160<span class="sup">o</span>C.
