Technical Capabilities

RONA is a high-tech enterprise specializing in the research, design, production of flexible industrial cables. Leveraging advanced international technologies, proven manufacturing processes, and a professional R&D team composed of experienced domestic cable experts, we are committed to delivering durable, high-performance cable solutions for demanding environments.

Before leaving the factory, our cables undergo rigorous, specialized testing:

Strict Quality Inspection

Flat-Plate Vulcanizing Press

It press prepares uniform sheet specimens by controlling temperature, pressure, and time. This identifies raw material defects like gels (fish eyes), black spots, staining, and uniformity issues.

Copper Conductor Quality Control

Resistance Testing: Utilizing both Wheatstone bridge and digital micro-ohmmeters to measure conductor DC resistance.
Visual Inspection: Checking for surface defects.
Combustion Test: Verifying oxygen-free copper purity via flame application.

Insulation Integrity Testing

Employing high-voltage insulation testers to verify insulation withstands peak voltage without breakdown, ensures uniform thickness, and prevents conductor breakage under external stress.

Tensile Strength Testing

Tensile Test (Universal Testing Machine)
Confirms permanent deformation of materials remains＜0.5%
Tensile Dissection Analysis
Provides objective assessment of the structural integrity and design effectiveness of flexible reinforcement.

High-Cycle Flex Endurance Test

Subjects cables to 1.5 million continuous bending cycles at a reduced bend radius, high speed, and rapid frequency. This accelerated testing equivalently simulates approximately 6.5 million cycles under typical operational conditions.

Accelerated Aging Test (Aging Oven)

Simulates long-term environmental degradation of cable jackets under various operating conditions in a compressed timeframe, providing a scientific basis for material selection.

Precautions For Installing Drag Chain Cables

During reeling and unreeling, the drag chain cable must remain in a free, untwisted state to avoid internal torsion or cable rotation. (Figure 1 shows the correct handling method: rotate the cable reel instead of pulling the cable directly, allowing it to gradually release internal torsional stress.)

Cables with larger outer diameters should be placed on both sides of the drag chain,while smaller cables should be arranged in the center and separated to prevent tangling or mechanical interference.

The cable’s minimum bending radius must match the bending radius of the drag chain to ensure safe, long-term operation.

Both ends of the cable must be securely fixed at the entry and exit points of the drag chain to prevent unwanted movement.

The cable length inside the drag chain must be properly matched to the drag chain’s travel length to avoid excess tension or slack during motion.

RONA is a premier high-tech company specializing in the research, design, and production of special flexible cables. We provide reliable connectivity solutions through professional engineering technology and rigorous manufacturing standards.
