TVR with soft steel wire driving handle cable

TVR with soft steel wire driving handle cableIt is a high-performance control cable designed specifically for industrial lifting equipment such as bridge cranes, gantry cranes, etc. It is widely used in situations where frequent movement, bending, and mechanical stress are required. The "TVR" in its name usually represents the specific model or implementation standard of the cable, while "with soft steel wire" refers to the addition of a flexible steel wire reinforcement layer in its internal structure to significantly improve the tensile strength and mechanical durability of the cable, especially suitable for connection scenarios such as driving handles that require frequent operation and are easily pulled by external forces.

1、 Product Structure and Material Characteristics

TVR with soft steel wire driving handle cableThe structure usually consists of the following key parts:

1. Conductor: Made of high-purity oxygen free copper (OFC), it is mostly a multi strand thin copper wire twisted structure (such as Class 5 or Class 6 soft copper conductors) to ensure the flexibility and conductivity of the cable. This structure allows the cable to withstand repeated bending without easily breaking, adapting to the frequent operation needs of the handle.

2. Insulation: High performance insulation materials such as polyvinyl chloride (PVC) or cross-linked polyethylene (XLPE) are usually used. These materials not only have excellent electrical insulation properties, but also have good heat resistance, aging resistance, and flame retardancy, and can work stably in a temperature range of -20 ℃ to+70 ℃ or even wider.

3. Filling and isolation layer: In multi-core cables, non hygroscopic filling materials (such as PP rope or cotton yarn) are added between the insulated cores to maintain the roundness of the cable and prevent the cores from sticking to each other. Sometimes isolation layers (such as polyester tape) are also installed to enhance structural stability and anti-interference ability.

4. Steel Wire Reinforcement: This is the core feature of the cable. Multiple thin and soft steel wires are embedded in the center or outer layer of the cable to form a tensile skeleton. These steel wires have been specially treated to have good flexibility and fatigue resistance, and can maintain a certain degree of bending ability while withstanding tension. The presence of soft steel wire effectively prevents internal wire breakage caused by excessive force or accidental cable hooking by operators when using the handle.

5. Sheath: The outer sheath is usually made of highly wear-resistant, oil resistant, and UV resistant PVC or polyurethane (TPU) material. The protective sheath not only provides mechanical protection, but also has good resistance to chemical corrosion, which can resist harmful substances such as oil stains, acid and alkali in industrial environments.

2、 Main performance advantages

1. High tensile strength: The addition of soft steel wire greatly enhances the tensile strength of the cable, which can withstand tensile forces of up to hundreds of kilograms, far exceeding ordinary control cables and effectively extending their service life.

2. Excellent flexibility and bending life: Despite the addition of steel wire, the cable maintains good flexibility through optimized design such as spiral winding or center reinforcement, and can be repeatedly bent hundreds of thousands of times without damage in small radii.

3. High safety: Even under tension, the soft steel wire takes priority in withstanding tension, protecting the internal wires from damage, avoiding control failure caused by wire breakage, and ensuring operational safety.

4. Strong environmental adaptability: It has characteristics such as oil resistance, wear resistance, UV protection, flame retardancy (in accordance with IEC 60332 and other standards), and is suitable for complex industrial environments such as high temperature, humidity, dust, and oil pollution.

5. Stable signal transmission: For multi-core cables with control signal or encoder functions, good shielding design (such as aluminum foil+braided shielding) can effectively suppress electromagnetic interference and ensure accurate transmission of control signals.

3、 Application scenarios

TVR with soft steel wire driving handle cableMainly used for:

• Handle control for lifting equipment such as bridge cranes, gantry cranes, and cantilever cranes.

• Control unit connections that require long-distance dragging or frequent movement.

• Mobile control station in factory automation production line.

• Mobile equipment in heavy industrial environments such as ports, docks, and warehouses.

4、 Selection and installation precautions

1. Core selection: Choose the appropriate number of cores (such as 4-core, 6-core, 10 core, 18 core, etc.) based on the complexity of the controller control function, ensuring that all control signals and power lines can be reliably connected.

2. Length matching: Reasonably plan the length of the cable to avoid entanglement caused by being too long or excessive stretching caused by being too short.

3. Installation method: It is recommended to use a cable pulley system or cable chain for guidance to reduce stress concentration caused by direct suspension. If directly suspended for use, ensure that the cable has sufficient slack.

4. Avoid twisting: During installation, prevent the cable from twisting to prevent damage to the internal structure.

5. Regular inspection: Regularly check the wear of the cable sheath, whether the joints are loose, especially whether the soft steel wire is exposed or broken, and replace aging or damaged cables in a timely manner.

summary

TVR with soft steel wire driving handle cableIt is a safety component in industrial lifting equipment. Its soft steel wire reinforced structure greatly enhances mechanical strength and service life while ensuring electrical performance, effectively addressing the complex and ever-changing operational challenges in industrial sites.
