CABLE STRUCTURE:
Conductor:Class 5 tinned copper
Insulation:Power core:Polytetrafluoroethylene rubber(XJ-30)
Insulation shielding:Semiconductive tape
Ground core:Semiconductive rubber(if used as a wrap,it is a semiconductive tape)Control core:Polytetrafluoroethylene rubber(XJ-30)
Filling(optional):Edge sealing rubber strips or glass fiber ropes
Sheath:Chlorinated polyethylene or a mixture of other comparable materials(XH-03)
Technical Data Rated voltage:(U₀/U)0.66/1.14 kV
The maximum system voltage:(Um)1.1 times U
Temperature classification:Maximum operating temperature of the conductor:+75℃
Operating environment temperature:-20℃ to +45℃
Cable laying temperature:Not lower than 0℃(When the ambient temperature is below 0℃,the cable should be preheated.)
Min.Bending Radius:6×cable O.D
Finished product voltage test:Power wire core:3.7kV/5minutesControl wire core:1.5kV/5 minutes Installation method:The laying of underground cables in coal mines is divided into methods such as in level tunnels or those below 45℃,in chambers,and in vertical shafts or in tunnels above 45℃ or in boreholes.
