NYY NYY-J Low Voltage Power Cable , VV VV22 0.6/1KV Xlpe Insulated Pvc Sheathed

Product Specification

Low voltage NYY NYY-J VV VV22 xlpe dsta pvc power cable 

NYY is a kind of power cable, its full name is PVC insulated PVC sheathed steel tape armored power cable.

▼NYY ampacity calculation conditions

Ambient temperature: 40℃ for laying in the air; 25℃ for buried laying.

The working temperature of the cable conductor is 90℃. When the cable is buried in the ground, the soil thermal resistance coefficient g=1.0℃•m/W. However, this formula does not take into account the soil thermal resistance coefficient caused by water migration during long-term operation of the cable. The rising situation.

When the cable is buried in the ground, the distance between the cable axis and the ground is 700mm.

For flat laying of multiple cables, the calculation formula of the cable axis distance is S=2D

▼Advantages of NYY

1. It occupies a small area. Generally, it is laid in a trench, indoors, in a tunnel or buried in the soil. The insulation distance between the lines is small. It is not suitable for poles and towers, and basically does not occupy the space on the ground.

2. High reliability. Affected by weather conditions and surrounding environment, the transmission performance is relatively stable and the reliability is high.

3. It has a very high pressure. More favorable conditions for large-capacity development, such as low temperature, superconducting power cables, etc.

4. The distributed capacitance is larger, the maintenance workload is less, and the possibility of electric shock is less

Compressed Conductor easy for installation, UV - resistant , total protection for the cable
