Cross-linked polyethylene insulation power cable specification and load flow
XLPE insulated power cable
0.6/kV Specification and load flow of the power cable with cross-linked polyethylene insulation (including ordinary type, flame retardant, flame retardant, halogen free low smoke flame retardant type):
 
XLPE insulated power cable has high mechanical strength, good resistance to environmental stress, excellent electrical performance and chemical corrosion and other characteristics, light weight, simple structure, easy to use. This product is suitable for AC rated voltage Uo/U 0.6/1kV and below.
 
The main features of the fire retardant power cable are not easy to catch fire or ignition delay limited in a certain range, suitable for cable laying dense degree of power station, subway, tunnel, high-rise buildings, large industrial and mining enterprises, oil fields, coal mines and other places.
 
The main characteristics of the fire-resistant power cable is the cable in addition to the normal operating conditions the transmission of electricity, in a certain period of time to maintain the normal operation, suitable for nuclear power plants, subways, tunnels, high-rise buildings, etc.
 
Low smoke halogen-free flame-retardant cable features are by not only have the flame retardant performance, but also has low smoke and harmless (less toxic and corrosive), is suitable for cable flame retardant, smoke density, toxic index and other places, such as subway, tunnel, nuclear power station, etc.
 
Ordinary cable type:
YJV, YJLV crosslinked polyethylene insulated, PVC sheathed power cable
YJY, YJLY crosslinked polyethylene insulated and PE sheathed power cable
YJV22, YJLV22 XLPE insulated PVC sheathed power cable
YJV23, YJLV23 XLPE insulated steel tape armored PE sheathed power cable
YJV32, YJLV32 XLPE insulated fine steel wire armoured PVC sheathed power cable
YJV33, YJLV33 XLPE insulated fine steel wire armoured PE sheathed power cable
 
Flame retardant cable type:
ZA, ZC, and ZB are added to the common type power cable model.
 
Fire resistance cable type:
Before the ordinary type of power cable type add N
 
Non halogen low smoke cable type:
WDZ-YJY, WDZ-YJLY- crosslinked polyethylene insulation, flame retardant polyolefin sheathed halogen free cable
WDZ-YJY22, WDZ-YJLY22- XLPE insulation halogen-free flame retardant polyolefin sheathed cable
WDZ-YJY32, WDZ-YJLY32- XLPE insulated fine steel wire armored halogen-free flame retardant polyolefin sheathed cable
 
Cross-linked polyethylene insulation power cable load flow computational formula:
Pe:Rated power
Pj:calculate active power
Sj:Computing power now
Ij:calculating current
Kx:simultaneous factor
cosφ:power factor
Pj=Kx*Pe
Sj=Pj/cosφ
When the single-phase power supply,Ij=Sj/Ue
When the three phase power supply,Ij=Sj/√3Ue
 
If adopt ~220V single phase power supply,simultaneous factor Kx is 1.0,power factor cosφ is 0.8,then Pe=13KW
Pj=13*1=13KW
 
Ij=1300/(0.8*220)=7.39A
I=P/(U*1.732*0.8) S=I/5 I=current P=power?U=voltage?S=wire cross-sectional area
