8.7KV 10KV Underground Copper Electric Cable
1.Application 
Medium voltage power cable for static application in ground, within and outside facilities, outdoor, in cable canals, in water, in conditions where cables are not exposed to heavier mechanical stress and tensile strain. Due to its very low factor of dielectric loss, which remains constant over its entire operating lifetime, and owing to excellent insulation property of XLPE-material, firmly longitudinally spliced with inner and external screen of semi-conductive material (extruded in one process), the cable has a high operating reliability. Used in transformer stations, switching blocks, in electric power plants and industrial plants. To avoid the effects of external impact, the adhering semi-conductive layer extruded between conductor and insulation, along with concentric copper conductor, secures restriction of electric field and resistance to partial discharges.

Standards:
IEC60502-2

Construction
Conductor:Cu round conductor, multi wire stranded compacted (RM), class 2 acc. to  IEC 60228 
Inner Screen:extruded semi-conductive skin on conductor
 Insulation:XLPE (cross-linked polyethylene, recent mark: PE-X)
 External Screen:extruded semi-conductive skin on insulation, longitudinally spliced with insulation (+ tape of conductive material)
Concentric Conductor:in inner layer corrugated spirally wrapped copper wires, in external layer copper tape wrapped in counter-helix
Sepeating Tape Sheath:PVC compound 
Sheath Colour: Black

Technical data
Temperature Range:
During Installation:-5 °C up to +70 °C
max. operating temp: +90 °C
at short circuit of max. 5 s:up to 250 °C
Minimal Inner Bending Radius: 15D

The EV industry has been developing by leaps and bounds in recent years. 60V LFP power supply, small in size and light in weight, works as an ideal power alternative to replace the traditional toxic lead acid battery. Li-phosphate offers good E-chemical performance with extra low inner-resistance. The key benefits are high current rating, long cycle life, good thermal stability, enhanced safety, environmental friendliness, and tolerance if abused.
