Drag chain cables come in a wide variety of models, each differing in structure, performance, and application scenarios. The following provides a detailed introduction to common drag chain cable models:
TRVV Type
Structure: The copper core is insulated with nitrile polyvinyl chloride, with an outer nitrile PVC sheath. The conductor is generally composed of multiple strands of ultra-fine finely twisted oxygen-free copper wire, which gives the cable excellent flexibility.
Features: Has certain oil resistance and wear resistance, suitable for dry or humid indoor environments. It has good bending resistance and can meet the usage requirements of frequent bending of equipment to a certain extent.
Application scenarios: Commonly used in equipment such as CNC machine tools and logistics conveyor systems as power transmission cables, providing stable electricity for equipment operation.
TRVVP type
Structure: Based on TRVV, a soft-sheath tinned copper wire braided shielding layer is added. The conductor and insulation layer structure are similar to TRVV.
Feature: Due to the presence of the shielding layer, it can effectively block external electromagnetic interference, ensuring the stability of internal transmission signals, while maintaining the oil resistance and wear resistance characteristics of the TRVV.
Application Scenario: Suitable for occasions with requirements for electromagnetic compatibility (EMC), such as servo systems, automated production lines, etc. It is commonly used to connect devices that are sensitive to signal interference, ensuring that signal transmission is not affected by external electromagnetic noise.
TRVVSP Type
Structure: Uses copper core with nitrile PVC insulation and sheath, with twisted pair design for the conductors and an overall shielding layer. The conductor is also made of multi-strand ultra-fine braided oxygen-free copper wire.
Features: It has excellent electromagnetic compatibility characteristics. When paired with a twisted structure and shielding layer, it greatly enhances anti-interference capability. Compared with ordinary shielded cables, it can better suppress common-mode and differential-mode interference.
Application scenarios: Commonly used for signal transmission in environments with high electromagnetic interference, such as connections for devices like encoders and sensors, ensuring precise signals are transmitted accurately and ensuring the stable operation of device control and feedback systems.
RVVYP type
Structure: The copper core uses a special nitrile mixed insulation material, covered with a special nitrile mixed sheath, and comes with an overall shielding layer.
Features: It has outstanding oil resistance, effectively preventing oil corrosion of the cable in environments with heavy oil contamination, which could affect its performance, while the shielding layer can resist electromagnetic interference.
Application scenarios: Mainly used in places with severe oil pollution, such as machining workshops and inside ships, serving as power and signal transmission cables for equipment.
