Shanghai Suoqi's highly flexible oil-resistant drag chain shielded cable is a special wire and cable suitable for bending resistance in dragchain equipment. Below is a detailed introduction:
Product models: Common domestic models include TRVVP and TRVVSP. Among them, TRVVP is a movable bend-resistant wire and cable with PVC insulated and sheathed and shielded layer, i.e., shielded drag chain cable; TRVVSP is a mobile bend-resistant wire and cable with PVC insulated and sheathed, shielded layer, and double-twisted core wires, also known as twisted pair shielded drag chain cable.
Product Features:
High flexibility: Uses multi-strand finely twisted oxygen-free fine copper wire stranded wire conductors, ensuring the flexibility and flexibility of the wire core, suitable for frequently moving situations.
Bending resistance: Optimized cable pitch, special structural design, and selection of high-quality raw materials ensure long-term operation in high-frequency bending scenarios without core breakage. The designed bending cycle life is 5 million cycles, with actual usage exceeding 6 million cycles.
Anti-interference: The overall woven shielding density exceeds 85%. Combined with a special structural design, it effectively resists external and internal cable interference, ensuring signal transmission stability.
Tensile strength: The cable is filled with high-degree Kevlar fiber, PVC core rope, or polyester yarn, and wrapped with high-quality non-woven fabric to form a rounded form, allowing it to evenly withstand tensile forces and ensure long-term effective operation.
Oil and wear resistance: Made with high-quality blended sheath materials, featuring wear resistance, oil resistance, and slow aging. Additionally, it features waterproof, acid and alkali resistance, radiation protection, and corrosion resistance. Imported TPU specially used sheath material is suitable for deep-sea and other harsh environments.
Customization: Colored or coded wire cores can be customized according to customer requirements. Core insulation color, sheath color, and cable length can all be customized according to customer requirements.
Cable structure:
Conductor: Usually pure copper multi-strand stranded conductors, but tin-plated copper wire conductors may also be used when special requirements are required.
Insulation: Generally, special elastomer PVC blends are used, which have better tear resistance compared to ordinary PVC materials and can effectively prevent insulation cracking, conductor entanglement, and short circuits.
Filling: PVC wire core, Kevlar tensile fiber rope, high-quality jute rope, etc., can be used to make the cable rounder and more neat. If tensile performance is required, Kevlar tensile fiber rope is generally preferred.
Core wire wrapping: Made from high-quality nonwoven fabric with moisture-proof properties, helping to improve cable roundness.
Shielding layer: Made of tin-plated copper wire braided, with a weave density above 80%, and can be increased according to customer requirements.
Outer sheath: Made with high-quality PVC blends and special reinforcements, and polyurethane materials can also be used according to customer requirements.
