YY2001 Ultra High Flexible Ultra High Speed Drag Chain TRVV Towline Cable Bending Resistance

Explanation of cable load capacity:

In long-travel drag chain applications, due to the weight of the cable itself and the stress generated during high-speed movement of the drag chain, as well as the limited freedom of cable installation in long-travel drag chains, the cable itself needs to withstand significant tensile forces. The longer the travel distance of the drag chain, the greater the forces applied, thus requiring higher load capacity for the cable

High Load: Suitable for applications with drag chain travel distances up to 100 meters, with high load capacity. Examples include the 20 million cycle YY2001, YY2002, YY2006 series with PVC sheathing.

Very High Load: Suitable for applications with drag chain travel distances up to 200 meters, with extremely high load capacity. Examples include the 20 million cycle YP2001, YP2002, YP2006 series with PUR sheathing.

Application

● The conductor is made up of ultra-fine copper wires (less than 0.08mm) twisted together, while conductors above 0.5mm are grouped together.

● The cable adopts a compacted structure, resulting in a relatively firm feel compared to a wrapped structure.

● It has good rigidity and strong load capacity. It is wear-resistant and moderately oil-resistant.

● Under normal installation and usage conditions, the service life can exceed 20 million cycles, making it suitable for use in high-speed motion drag chains.

It is particularly well-suited for use in large equipment such as CNC machines where high-speed bending in drag chains is required.

● Tinned copper (below 0.5mm²) or bare copper (0.5mm² and above) conductors, ultra-fine copper wire, compliant with DIN VDE 0295 Class 6 and IEC 60228 Class 6.

●Special PVC insulation.

●Color-coded cores (below 0.5mm²).

●Black cores with continuous white numeric marking (0.5mm² and above), with yellow-green grounding wire on the outer layer (3 cores and above).

●Optimal pitch twisted cores (12 cores and above), layered twisted below 12 cores.

● Low viscosity, oil-resistant PVC-based composite material

● Grey or color can be customized according to customer requirements.

G= represents the yellow-green grounding wire. For more specifications or special custom products, please contact our product consultant.

It is recommended to split the high-speed drag chain cable with 20 cores or more into two separate cables.

For the cables ordered by the coil above, the minimum order quantity for cables with PUR sheath type is 400 meters.

High-flexible drag chain cable testing standards

(10 million times reliability tests for drag chain)

1.Drag Chain Bending Test

Test method: Take a 2-meter finished cable assembly, bend it with a radius 6 times the outer diameter of the cable, move it back and forth for a travel distance of 900mm at a speed of 90 cycles per minute.

Judgment criteria: 1. Over 20,000,000 cycles of reciprocating movement without open circuit or short circuit. 2. No breakage in the sheath.
