Shanghai Suoqi Cable Co., Ltd. is deeply engaged in the field of special flexible cables. The following provides a professional interpretation of flat cables from three dimensions: material structure, performance advantages, and application scenarios.
1. Materials and Structural Parameters
The flat cables with steel wire from Shanghai Suoqi and flat power cables have excellent performance and a wide range of applications. The following is an introduction to the related products: Product models and structure: Common models include YVFB, YVFBG, YFFB, YFFBG, etc. Among them, YVFB is a mobile flexible flat cable with PVC insulated nitrile sheathing; YVFBG is a flat cable with double steel wire added on this basis; YFFB is a mobile flexible flat cable with nitrile insulation and nitrile sheathing, and YFFBG is its double steel wire version. The cable conductors are usually made of multi-strand fine oxygen-free copper twisted wires, the insulation material is high-quality PVC insulation or elastomeric nitrile insulation, the cores can be arranged in a straight line or in a star pattern, and the outer sheath is made of elastomeric nitrile sheathing material.
Product Features Good Flexibility and Bend Resistance: The conductor is made of multiple strands of finely twisted oxygen-free copper wires, ensuring the softness and flexibility of the wire core. At the same time, the cabling pitch is optimized, using a special structural design and high-quality raw materials, making it durable and not easy to break under frequent bending.
Strong tensile performance: Equipped with a steel wire load-bearing core, such as high-strength galvanized double steel wires, it can withstand considerable mechanical impact stress and can be used in long-distance suspension scenarios to ensure that the cable will not be pulled apart under the effect of gravity.
Space-saving: The cable is flat, with a smaller bending radius compared to round cables, which can save installation space, and multiple cables can be overlapped and bundled together.
Excellent environmental adaptability: It features cold resistance, wear resistance, oil resistance, waterproofing, acid and alkali resistance, radiation resistance, and corrosion resistance. The imported TPU sheath material used can adapt to seawater and other harsh environments, with a typical temperature resistance range of -15°C~70°C or -40°C~70°C.
Technical parameters: The rated voltage is usually U0/U 300/500V. When the core wires are arranged in a single-row straight line, it is recommended to add load-bearing steel wire or polyester yarn if the suspension length exceeds 40m and the moving speed exceeds 2m/s; when the core wires are arranged in a plum blossom-type stranding, it is recommended to add load-bearing steel wire if the suspension length exceeds 80m and the moving speed exceeds 4-10m/s.
Scope of application: Widely used in mobile equipment such as vehicles, trolleys, and transmission machinery, as well as in fields such as metallurgy, electric power, ships, logistics conveyor systems, and port machinery. It can also be used in occasions such as elevator control systems and video system connections.
2. Performance Technical Indicators
Rated voltage 450/750V to 0.6/1kV; small bending radius, minimum up to 5D (D is the cable outer diameter); applicable temperature range -20℃ to 80℃; has good flexibility and torsion resistance, stable and reliable for long-term mobile use.
3. Application Scenarios
Flat cables are widely used in fields such as industrial automation, hoisting and transportation, and ports and docks.
