High tensile strength reinforced drum cable, designed for frequent retraction and high mechanical stress scenarios, using central steel wire/aramid fiber reinforcement, with a tensile strength of 10-15kN, meeting EN 50396 standard. The conductor is made of multiple stranded tinned copper wires, with a bending resistance of over 5 million times. The insulation layer is made of weather resistant EPDM or XLPE, and the sheath is made of wear-resistant PUR material, which is resistant to oil, acid and alkali, and ultraviolet rays. Suitable for port machinery, cranes, stacker reclaimers and other equipment, it can operate stably in environments ranging from -40 ℃ to+90 ℃, and supports customized shielding, flame retardancy and other special properties. It is a reliable power transmission choice for heavy equipment.
High tensile strength reinforced drum cable
1. Product performance
High tensile strength: specially designed to cope with the huge tensile force generated by frequent retraction, dragging, and suspension of drum equipment, with a tensile strength of 10-15kN or even higher, effectively preventing cable breakage.
Excellent bending resistance: Using special structural design and fatigue resistant materials, the cable can maintain good electrical and mechanical performance even after millions of bending cycles.
Good weather resistance: Suitable for harsh outdoor environments such as sun and rain, high and low temperatures (usually -40 ℃ to+90 ℃), ozone aging, etc.
Oil resistant, acid alkali resistant, and corrosion-resistant: The sheath material has excellent chemical stability and can work stably in corrosive environments such as oil stains and acid bases.
Stable electrical performance: Ensure stable and reliable power transmission under various working conditions, such as high electromagnetic interference environments.
2. Materials used
Conductor: Stranded multiple strands of fine copper wire (Class 5 or Class 6), tin plated, with good flexibility and strong oxidation resistance.
Insulation layer: commonly used materials with good weather resistance, such as EPDM (ethylene propylene diene monomer rubber), XLPE (cross-linked polyethylene), or PVC with special formulations.
Strengthening components:
Central reinforcement: usually high-strength galvanized steel wire, aramid fiber (Kevlar) or glass fiber reinforced plastic (FRP), providing the main tensile support.
Auxiliary reinforcement: It is possible to add aramid weaving layer or steel wire weaving layer under the sheath to further enhance the tensile and lateral pressure resistance.
Sheath: Made of highly wear-resistant, oil resistant, and weather resistant polyurethane (PUR) material, or using chloroprene rubber (CR) according to special requirements.

4. Model (Example)
Conventional power type: such as YJV-RE (cross-linked polyethylene insulation, polyvinyl chloride sheath, soft structure, for use in drums), YZ-RE (medium-sized rubber sheathed flexible cable, for use in drums).
High tensile reinforcement type: The model usually includes reinforcement components, such as YJV-RE-K (K represents armor or reinforcement), or more specifically PUR-TPU-ST (polyurethane sheath, thermoplastic polyurethane, with steel wire reinforcement).
Manufacturer customized model: Many manufacturers have their own naming system, such as TRVVSP (drag chain cable, twisted pair shield), which can sometimes be used for lightweight reels, but high tensile reel cable models may include words or specific codes such as "reel", "reinforced", "tensile", etc.
Example model:
Drum cable JHSR (waterproof rubber sheathed flexible cable, for drum use)
High tensile drum cable YZW-RE-J (J represents reinforcement)
Heavy duty drum cable UGFBP (mining high-voltage rubber sheathed flexible cable, copper wire braided shielding, for drum use)
5. Purpose:High tensile strength reinforced drum cable
Port machinery: shore crane (STS), yard crane (RTG/RMG), gantry crane, unloader, loader.
Lifting equipment: tower crane, gantry crane, bridge crane, crawler crane.
Material handling equipment: stacker reclaimer, bucket wheel machine, dump truck, grab bucket unloader.
Mining equipment: mining hoist, scraper conveyor (some moving parts).
Amusement facilities: large roller coasters, Ferris wheels, and other facilities that require cables to move with the equipment.
Other: Any mobile device that requires cables to be repeatedly retracted and coiled on a drum, subjected to significant tensile and bending stresses.
6. Packaging
Loop packaging: Usually wrapped around cable reels according to customer requirements or standard lengths (such as 100 meters/loop, 200 meters/loop, 500 meters/loop).
Cable reel: Use wooden or steel cable reels to ensure that the cables are not damaged during transportation and storage, and to maintain their roundness.
Packaging label: The product model, specifications, length, rated voltage, standard, manufacturer, production date, gross/net weight, and other information will be clearly marked on the cable reel or outside the packaging.
Protection: The edge of the cable reel may be protected to prevent the cable from being scratched during transportation.
7. Product advantages
Long service life: Due to its excellent tensile, bending, and wear resistance, it has a longer service life in drum applications compared to ordinary cables, reducing replacement frequency and maintenance costs.
High reliability: The stable electrical and mechanical performance ensures the continuous and reliable operation of the equipment under harsh working conditions, reducing the risk of shutdown.
High safety: Good flame retardancy, weather resistance, oil resistance, and reliable structural design enhance the safety of equipment operation.
Strong adaptability: Products with different specifications and performance (such as high and low temperature resistance, corrosion resistance, shielding, etc.) can be customized according to different application environments and equipment requirements.
Reduce total cost: Although the initial procurement cost may be higher, considering its long lifespan and low maintenance requirements, the total cost of ownership (TCO) is better.
