Applications
Flexible low voltage reeling cable for application under extreme mechanical stresses, specially designed for vertical reeling operation (spreader reeling application). These cables are used for frequently changing dynamic loads, such as reeling cables for scoops (LHDs) in underground mines, suitable for mono-spiral reels and cylindrical reels.
Standards
Brand CORDAFLEX(SMK)-V
Type designation (N)SHTOEU-J/-O
Standard Based on DIN VDE 0250-814
Construction
Design features
Conductor Electrolytic bare copper, very finely stranded class FS
Insulation Special thermoplastic compound providing very high stability, best insulation resistance and excellent gliding characteristic
Core identification Best identification as a result of black colored insulation with light printed numbers, earth conductor green-yellow
Individual screen Braid screen made of tinned copper wires. Transfer impedance optimized at 30 MHz.
Surface covered: at least 60% for shielded cores; at least 80% for twisted pairs
Core arrangement Laid-up in a maximum of 3 layers Support element Central aramide support element to increase the loading capability.
The kN value designates the breaking load of the support element
Sheath system - PROTOFIRM Special - Inner sheath: High grade special compound based on PCP, color: yellow;
- Anti-torsion braid: Reinforced braid made of polyester threads, in a vulcanized bond between the sheaths, resulting in a high strength of the sheath system;
- PROTOFIRM Special - Outer sheath: A sheath system with a unique combination of flexibility and robustness has been achieved through the use of this structure.
Abrasion and tear resistant special rubber compound based on PCP, color: yellow.
