The high-voltage bucket turbine reel cable is a special cable used for bucket wheels and other large mechanical equipment. The following will introduce it from the perspectives of its application range, performance features, structure, and materials:
Scope of application
Ports and docks: At ports and docks, bucket turbines are used to load and unload bulk cargo such as coal, ore, and grain. High-voltage bucket turbine reel cables provide high-voltage power transmission for various components of the turbine, such as the bucket wheel drive, belt conveyor, pitch and slewing mechanisms, ensuring efficient operation of the equipment.
Mining: In mining environments such as coal mines and metal mines, bucket wheels are used for ore stacking and conveying operations. High-voltage bucket wheels can stably supply power to bucket wheels under harsh mining conditions, such as humidity, dust, and corrosive gases, ensuring continuous mine production.
Power industry: In coal storage yards of power plants, bucket turbines are responsible for storing and extracting coal. High-voltage bucket turbine reel cables transmit high-voltage electrical energy from substations to bucket turbines, meeting the high-power electricity needs of bucket turbines and ensuring smooth coal supply during power generation.
Metallurgical industry: In metallurgical enterprises such as steel mills and coking plants, bucket turbines are used for raw material picking and conveying, such as iron ore and coke. High-voltage bucket turbines reel cables provide power to the turbines, supporting the smooth progress of the metallurgical production process.
Cement industry: In the raw material and finished product yards of cement plants, bucket turbines are used for material storage and retrieval. High-voltage bucket turbine reel cables provide stable power to the turbines, ensuring the normal operation of material supply and conveying during cement production.
Performance characteristics
Excellent electrical performance: It has high voltage resistance, capable of withstanding rated voltages of 6/10kV and above, ensuring safe and stable operation in high-voltage transmission environments. At the same time, it has high insulation resistance, which can effectively reduce leakage current and energy loss.
Good mechanical performance: It has high tensile strength, capable of withstanding the tensile forces generated by the bucket wheel machine during operation, preventing cable breakage. In addition, it also has excellent wear resistance and tear resistance, able to adapt to frequent winding, unwinding, and moving conditions.
Strong environmental adaptability: Can operate normally within the temperature range of -40℃ to 105℃, with some cables able to withstand short-term temperatures up to 150℃. At the same time, it has characteristics of waterproof, moisture-proof, oil-resistant, corrosion-resistant, and flame-retardant, making it suitable for various harsh working environments.
Excellent bending performance: Small bending radius, generally ≤ 4 times the cable outer diameter, high resistance to bending cycles, ≥ 8 million times, can meet the requirements of frequent bending and winding of the bucket wheel machine drum.
Structure and Materials
Conductor: Made of multiple strands of ultra-fine oxygen-free bare copper wires twisted together, complying with VDE 0295 CLASS 5/6 standards, ensuring high conductivity and flexibility, suitable for conditions of frequent bending.
Insulation layer: Made of silicone rubber or modified elastomer materials, with a temperature range of -40℃ to 150℃, it can maintain stable electrical performance even in high-temperature environments.
Sheath: The outer sheath is usually made of polyurethane (PUR), which features wear resistance, waterproofing, oil stain resistance, and UV resistance. Some cables also have inner sheaths to protect the insulation layer and enhance the overall performance of the cable.
Reinforcement components: Inner layer composite tensile elements, such as galvanized steel wire ropes or Kevlar fibers, are used to prevent core breakage or sheath delamination caused by longitudinal tension, enhancing the cable's tensile strength and torsion resistance.
