Shielded Twisted – Pair Cable for Energy Chains/Drag Chain Shielded Twisted – Pair Cable/TRVVSP

Basic information of the product
Product name: High-flexibility drag chain twisted pair shielded cable
Model: TRVSP
Implementation standard: Complies with IEC 60332-1, VW-1 and other relevant standards.
Physical properties
Conductor:
Material: Multi-strand ultra-fine twisted oxygen-free copper wire, in line with VDE 0295 CLASS standard.
Wire diameter: Commonly 26AWG, 24AWG, 23AWG, etc. If 24AWG is used, the diameter of the single-core copper wire is about 0.51mm.
Number of strands: According to different wire diameters and current carrying requirements, it is generally 7 strands, 19 strands, 37 strands, etc.
Insulation layer:
Material: Usually PVC, PUR, etc., such as special modified PVC, which has oil resistance, moisture resistance and other characteristics.
Thickness: Generally around 0.5mm-1.0mm, such as 0.7mm.
Color: A variety of colors are available, such as red, black, blue, green, etc., and can also be customized according to customer requirements.
Wire core structure:
Number of cores: Commonly 2 cores, 4 cores, 6 cores, 8 cores, 10 cores, 16 cores, etc., up to about 40 cores.
Twisted pair mode: twisted in pairs, adjacent twist pitch settings are inconsistent to reduce signal interference.
Shielding layer:
Material: Generally tinned copper wire braided mesh or aluminum foil. If tinned copper wire braided mesh is used, the braiding density is usually above 80%.
Thickness: The thickness of tinned copper wire braided mesh is generally around 0.1mm-0.2mm, and the thickness of aluminum foil is generally around 0.05mm-0.1mm.
Sheath:
Material: Mostly high-elastic PVC mixture, PUR mixture, etc.
Thickness: Generally around 1.0mm-2.0mm, such as 1.5mm.
Color: Commonly black, orange, gray, green, etc., can be customized.
Outer diameter: Depending on the number of cores and wire diameter, it is generally around 3mm-10mm, such as the outer diameter of a 4-core 0.2 square drag chain twisted pair shielded cable is about 5mm.
Electrical characteristics
Rated voltage: Generally 300/300V, 300/500V, 450/750V, etc., with different voltages for different uses.
Test voltage: Usually between 1500V-5000V.
Characteristic impedance: Generally 100Ω±15%, within the specified frequency range.
Attenuation: When transmitting high-frequency signals, the attenuation value per 100 meters has certain restrictions, such as the attenuation does not exceed 3dB/100m at 10MHz.
Near-end crosstalk (NEXT): Within the specified frequency range, the NEXT value must meet the requirements of relevant standards to ensure the quality of signal transmission.
Mechanical properties
Tensile strength: Generally can withstand a tensile force of 100N-1000N without breaking, such as 100N.
Bending radius: When installed in mobile mode, when the stroke is less than 10 meters, the bending radius is generally 8 times the outer diameter of the cable; when the stroke is ≥10 meters, the bending radius is generally 10 times the outer diameter of the cable. When installed in a fixed position, the bending radius is generally 5 times the outer diameter of the cable.
Bending times: Generally can withstand 5 million, 10 million or 15 million bendings, and products from different manufacturers vary.
Other properties
Operating temperature range: When installed in a fixed position, it is generally -30℃ to 90℃; when installed in a mobile position, it is generally -5℃ to 90℃.
Flame retardancy: Meets relevant flame retardant standards, such as IEC 60332-1 and VW-1.
Service life: Under the specified usage conditions and bending times, it can generally be used for about 5 to 10 years. The specific service life is related to the actual usage environment and conditions.
