Features of TRVVSP twisted shielded drag chain cable
Special PVC drag chain cables for drag chains are economical cables for drag chains.
The twisted shielded cable structure is designed to transmit signals over long distances with low attenuation, anti-interference and high crosstalk resistance.
Due to the special cable structure, this cable zui is characterised by good flexibility. Resistant to bending, folding, abrasion, oil, for continuous reciprocating motion under the mobile use.
The twisted pair structure can effectively prevent crosstalk between neighbouring pairs, and the copper mesh braid shielding can also effectively prevent interference from both internal and external sources, making data transmission safer and more reliable.
TRVVSP Twisted Shielded Drag Chain Cable Application Areas
Widely used in CNC machine tools, vertical lathes, glass machinery, woodworking machinery, robot manipulators, cutting machines, engraving machines, door and window machinery and other automated machinery and equipment.

TRVVSP twisted shielded drag chain cable belongs to the common type of drag chain cable for engraving machine.

Ask
The softer the cable, the better?

Answer
Highly flexible drag chain cables are not as soft as they are. Although flexibility has a certain effect on the smooth running of the cable in the drag chain system, which can reduce the bending stress, but ‘soft’ means the structure of the object is loose, easy to be deformed after the force (as opposed to ‘hard’). If it is too soft, it may cause some problems. For example, it may cause the cable's tensile strength and compression resistance to decrease, and it may be easily damaged in some complicated application environments.

Ask
Why do drag chain cables with millions of cycles break in a few days?

Answer
The so-called millions of times of drag chain bends of drag chain cables are derived under specific experimental conditions, not in all equipment will have millions of times of drag chain bends. When the equipment environment is better than the experimental environment, the number of drag chain bends of the cable is high; on the contrary, when the environment of the equipment is worse, it may lead to a very rapid decline in the number of drag chain bends of the cable.
