VV Copper Core PVC Insulated PVC Sheathed Power Cable
 

Model meaning

V**- PVC insulation

V**- PVC sheathed

Cable full name

VV Copper core PVC insulated PVC sheathed power cable

Rated voltage

0.6/1KV

Product structure

From the inside out of the components were conductors, insulation layer, filling layer, (steel layer), sheathed layer. Now the most commonly used conductor material on the market is of course copper conductor; The insulating layer and the outer sheathed material are all PVC; Fill layer is generally some of the more softer nylon material, in order to prevent the cable between the inner conductor of the direct contact with each other extrusion; Steel tape armored VV cable for VV*2 cable, steel tape armor is the role of compression resistant,, can be used in the ground.

Standard

GB/T ****6.*****8

Application

This product is suitable for power frequency rated voltage 0.6 / 1KV and below the power cord.
 

Characteristics

1.The rated power frequency UO / U is 0.6 / 1KV.

2.Operating temperature:

Long-term working temperature does not exceed *0 ℃,the laying temperature is not lower than 0 ℃; When a short-circuit (the longest duration of no more than 5s) cable conductor allows the maximum temperature is **0 ℃ Cable laying ambient temperature should not be lower than 0 ℃.

3.Allowed bending radius: not less than *0 times the cable diameter;

Laying installation

Cable laying should use special tools, such as pay-off frame, guide roller etc., to prevent mechanical damage during the process of laying, away from heat source. When cable wearing tube and laying, the pipe diameter is not less than 1.5 times the cable diameter, multiple cable wearing tube to prohibit cable extrusion, the total area of the cable does not exceed *0% of the total area of the tube.

Use

Generally used as power transmission hub, often buried in the soil or laying in the room, channels, tunnels, the insulation distance between lines is small, no tower, an area of small, basic does not account for space on the ground.
