PROTOLON Reeling Cable
Flexible medium voltage reeling cables are designed for use in environments subject to high to extreme mechanical stresses. These stresses may include high travel speeds, dynamic tensile loads, multiple changes of direction across different planes, churning effects while running over rollers, and torsional stresses. These cables are primarily intended for mobile equipment, such as fast-moving container cranes and large machinery.
Design Features
Conductor: Conductor and earth conductor made of electrolytic copper tinned, very finely stranded, class FS (refer also to DIN VDE 0295)
Insulation
- PROTOLON
- HS High-grade special compound based on high-quality EPR (at least 3GI3); improved mechanical and electrical characteristics (refer also to DIN VDE 0207, Part 20)
Electrical Field Control: Inner semiconductive layer of EPR, outer semiconductive layer of modified NBR, capable of being stripped when cold and thus extremely easy to prepare (Easy Strip design)
Core Identification: Natural colored insulation with a black semiconductive layer
Core Arrangement: Three-core design, with earth conductor split into 3 parts positioned in the interstices
Sheath System
- PROTOFIRM Sandwich - double layer inner sheath: Special compound based on EPR, quality at least 5GM3, also serves as a water barrier, color: red
- Anti-torsion braid: Reinforced braid made of polyester threads, in a vulcanized bond between the sheaths, resulting in high strength of the sheath system
- PROTOFIRM Sandwich - double-layer outer sheath: A sheath system with a unique combination of flexibility and robustness has been achieved through the use of a new sandwich structure. Abrasion and tear-proof high-grade rubber compounds based on PCP, quality at least 5GM5, color: bright red/red
