Medium Voltage Reeling Cable 8.7/15kV flexible – Reeling Cable

Cable Type RNEDAFLEX-XT (N)TSKCGEWOEU
Voltage rating: 8.7/15kV
Cross-section 3×35+2x(7×2.5)mm2+1x(12E9/125+25KON), (N)TSKCGEWOEU-8.7/15kV Crane Flexible Cable
Application for use with mobile crane, continuous mining machines or longwall loading machines, heavy duty
trailing where more flexibility is desired to its medium and high voltage cable.
Construction
1.  conductor tinned copper of class 6, flexible stranded
2. Insulation based on high-quality EPR with improved
mechanical and electrical Ethylene Propylene
Rubber (EPR)
3.  Inner semiconductor Ethylene Propylene Rubber (EPR) same as
insulation, black color
4.  Outer semiconductor extruded NBR of Easy Strip plan
5.  Ground conductor mixed braid of tinned copper wires and Kevlar
aramid yarn to conduct earth and impart superior
tensile and torsional resistance. each braid has
25/2 sqmm.
6.  Inner sheath compounds based on PCP
7.  Anti-torsional braid Kevlar braid of high-strength, embedded in the
sheath
8.  Central support Kevlar semiconductive rubber cradle seperator
with Kevlar polyester rope centered
9.  Outer sheath special compounds based on PCP with excellent
strength and anti-abrasion characteristics, red
color
10.  Control cores tinned copper strand with HEPR insulation,
Kevlar polyester rope centered and Kevlar
spinning around the 7×2.5 group
11. Fiber optical fiber optic unit with ETFE sheathed and Kevlar
threads reinforced with max. tensile load up to 1600N.
