TRVV cable is a highly flexible drag chain cable used in industries such as mobile equipment, robotics, and CNC equipment. Below, we'll explain what TRVV cable is and the differences between TRVV and TRVVP cables.
1. What is TRVV cable?
TRVV cable is a highly flexible drag chain cable used for connection and control. It is widely used in drag chain systems that require free reciprocating movement and no forced tension, whether in dry or humid indoor environments. These systems include machine tools, logistics conveying systems, port machinery, and complete equipment installation projects.
What material is TRVV cable made of?
Cable construction: Multi-strand copper wire or tinned copper wire stranded conductor; sheathing materials include polyvinyl chloride, low-smoke halogen-free, cross-linked polyethylene, butyl cyanoacrylate polyvinyl chloride, polyurethane, and specialty composites.
Technical Parameters: Temperature Range: -40°C - +80°C
Bending Radius: 7.5 x Cable Outer Diameter
Operating Voltage: 300V/500V
II. TRVV Cable Models
What does TRVV cable mean and what does the TRVV cable code mean?
T - Cable type, indicating drag chain cable
R - Flexible cable
V - Polyvinyl chloride (PVC) insulation
V - Polyvinyl chloride (PVC) sheath
S - S indicates twisted pair
P - Copper wire braid shield
TRVVP cable consists of multiple soft copper wires twisted together, covered with PVC insulation to form the "wire core." Multiple wire cores are then twisted together to form the "cable core," which is then braided with copper wire and then covered with a PVC outer sheath.
3. TRVV Drag Chain Cable Standards
Unshielded TRVV drag chain cables comply with the standard GB/T5023.5-2008, "Polyvinyl chloride insulated cables for rated voltages up to and including 450-750V - Part 5: Flexible cables (cords)." Other types of drag chain cables comply with the national standard for that cable type. For example, shielded cables comply with the relevant national standard for shielded cable models.
4. Differences between TRVV and TRVVP Cables
1. TRVV stands for flexible drag chain cables with copper core conductors, PVC insulation, and PVC sheathing. TRVVP stands for flexible drag chain cables with copper core conductors, PVC insulation, PVC sheathing, and a braided copper shield. These cables are typically braided with tinned copper wire or covered with aluminum foil to reduce external signal interference.
2. Both TRVVP and TRVV are flexible drag chain cables, with TRVV being unshielded and TRVVP being shielded. The shielding layer isolates electromagnetic noise sources from sensitive equipment, cutting off the noise's propagation path.
