Product Description

electric wire and cable 20mm/20mm electric cable/20mm electric wire

1.Brief introduction of electric wire and cable 20mm

 This  electric wire and cable 20mm   is suitable for fixed laying in power plant with AC rated voltage up to and including 450/750v

2.The  electric wire and cable 20mm standard .

GB/T5023-2008<Rated voltage 450/750v and below PVC insulation wire and cable>

JB8734-1998<Rated voltage 450/750v and below PVC insulation wires and flexible wires>

3.Service of the  electric wire and cable 20mm  

A:When the price electric cable 25mm2 used in AC system ,the cables rated voltage should be at  least equal to nominal voltage that used in cable
system ;

B:When the household wire and cable  used in DCsystem,the system’s nominal voltage should not           more than 1.5 times of the cable’s rated
voltage .

C:Long-term permissible working temperature of cable shal not exceed 70°c,the layout temperature        of cable shall not be lower than 0°c .

D:Permissible bending radius of cable :the cable whose O.D is shorter than 25mm,its radius shall not     be less than 4 D.the cable whose O.D is
25mm or more than ,its radius shall not be less than 6 D .

E:Cable packed in circle or roll ,its length should be 100m,length tolerance ±0.5m(the same below)

F:Finished insulated core and finished power line ,can bear the AC voltage test stipulated after being     put in the water under room temperature of
20±5°c at least 1 hour .

G:The  electric wire and cable 20mm   has good electrical insulation property,mechanical property and no flame propagetion property ,it has reliable
quality and is durable and convenient for use .

4.Other special characteristics: Design and manufacture according to customers’ request

A:Drawing(to make the raw copper rod into copper wires) 5.The process of electric wire and cable 20mm 

B:Stranding(to make the copper wires into bunch stranded copper conductor)

C:Insulating (to insulate the copper conductor with PVC ,PE,XLPE or EPR and so on )

D:Laying-up (to make the insulated conductors and inner fillers into one cable by cabling machine)

E:Braiding(to cover the cable with tinned copper or galvanized steel wire braid to screen or strength                         the cable)

F:Sheating(to cover the cable with PO(SHF1) cross-linked PO(SHF2) or PVC as inner or outer    

     sheath)
