PVC Insulated And Sheath Electric Cable

Applications and Properties

The cable is used as power distribution and transmission line at rated voltage 0.6/1KV which can be fixed installed.0.6/1KV PVC insulated fire-resistance power cable is designed and manufactured according to GB/T12706-2008(Equivalent to IEC60502),its physical and electrical performance is the same as common plastic power cable.Its fireproof performance confirms to GB/T19216(Equivalent to IEC60331),therefore,this kind of product not only can transmit power for 120min in fire of 750-800℃this kind of cable is especially suitable for important locations such as tall building,underground railway,power station ans so on,where requires ability of fire-control.

Model

Name

NH-VV

PVC insulated and sheathed fire-proof electric power cable.

NH-VV22

PVC insulated and sheathed steel tape armored fire-proof electric power cable.

Features

The long-time working temperature of cable should not be higher than 70℃.
When core in in short-circuit(max 5s)the temperature should not exceed 160℃.
While installation the ambient temperature should not be lower than 0℃ and the bending radius should not be less than 10 times of outer diameter of cable.

Structure and Size of the Cable

VV, VLV, ZRVV, ZRVLV, 0.6/1KV PVC insulated PVC sheathed flame retardant and non-flame retardant power cable.

Installation

The installation temperature should not over 20℃,if the ambient temperature is lower than 0℃,the cable should be preheated.
The bending radius of cable should not less than 8 times.
After installation,the cable should withstand voltage test for 15min,3.5kv D.C

Installation in Air

1. As the single core cable laying in parallel,the distance between the cable:center is 2 times(for cables,which cross sectional area of conductor≦185mm²)and 90mm²(for cables,which cross sectional area of conductor≦240mm²).
2. Ambient temperature: 30℃.
3. Max temperature of conductor: 70℃.
4. Rating factors of current rating for ambient temperature.

Installation in Ground

1.When the single core cables are installed separately,the distance between the cable:center is 2 times of the cable diameter.
2.Ambient temperature: 25℃
3.Max temperature of conductor: 70℃
4.Soil thermour resistivity:1.0°m/w
5.Depth: 0.7m
6.Rating factors under different ambient temperature
6. Current Rating
0.6/1KV copper conductor PVC insulated PVC sheathed flame retardant and non-flame retardant power cable installed in air for long term continuously load.
