Buflex SEM OFE Reeling Cable with integrated Optical Fibre Application

• Container Cranes: Used in shore-based container cranes (STS), rubber-tired/rail-mounted gantry cranes (RTG/RMG), and similar equipment, these systems simultaneously supply power and transmit data such as lifting gear status and equipment health monitoring during frequent lifting and travel operations.
• Grab Unloaders: At bulk cargo terminals, cables are rapidly wound and unwound on drums to provide power and control signals to equipment such as grabs.
• Shore Power Systems: Used to supply power to berthing vessels while facilitating data exchange.
• Surface and Underground Mining Equipment: Such as excavators and rock-drilling rigs. As these machines operate in harsh mining environments, the cables require extremely high mechanical strength and abrasion resistance.

Buflex SEM OFE Reeling Cable with integrated Optical Fibre Feature

• EPR Insulation and Shielding: Ethylene-propylene rubber (EPR) insulation is used in conjunction with conductor shielding and an insulating shielding layer. A three-layer co-extrusion process ensures there are no air gaps, effectively preventing partial discharge (corona) and ensuring the long-term operational safety of the cable. Each phase conductor is equipped with an independent shielding layer, providing excellent electromagnetic shielding performance.
• High Mechanical Strength: The cable features a 3+2+1 symmetrical six-core structure (3 power conductors + 2 protective ground conductors + 1 optical fiber unit), which maintains a round profile during reel extrusion and bending while evenly distributing mechanical stress to protect the fragile optical fibers.
• Wide Temperature Range and Compact Design: The dynamic operating temperature range is -30°C to +80°C, and PUR maintains its flexibility even at low temperatures. Compared to traditional neoprene cables, the outer diameter is reduced by 12–20% and the weight is reduced by 18–28%, effectively lowering reel load and equipment energy consumption.
