Product Introduction
The flat cable series launched by Shanghai Suoqi Wire & Cable Co., Ltd. adopts a flat structure design, suitable for space-constrained power supply and signal transmission scenarios requiring reciprocating motion with equipment. Typical applications include elevator accompaniment, overhead carts, automated machine tools, stage equipment, and gantry cranes. Compared to circular cables, flat structures distribute force more evenly and arrange more neatly during repeated bending, significantly reducing bending radius and improving space utilization. The product supports customization by core count, width, length, and special structures.
Operating Condition Pain Point Analysis
The core problems faced by flat cables come from three aspects. First, tight space arrangement. In spaces such as elevator shafts, machine tool drag chains, and stage rigging, the space is compact. Round cables occupy a large cross-sectional area and have a large bending radius, which easily causes friction and interference with surrounding structures; the flat structure can be laid closely against the installation surface, saving space. Second, fatigue from repeated bending. Elevator trailing cables and crane trolley cables move hundreds of times daily with the equipment, requiring the cable to maintain stable conductor and insulation structures under high-frequency bending. Ordinary cable cores in the bending area are prone to displacement, wear, and even breakage. Third, environmental corrosion and wear. Some application scenarios involve oil, dust, sunlight, and temperature variations, so the jacket needs to be oil-resistant, wear-resistant, and weather-resistant. At the same time, as the cable moves, it rubs against rails and brackets, and the jacket’s wear resistance directly affects its service life.
Product Technology Analysis
From the perspective of raw material selection, the flat cable conductors are made of multiple strands of fine, soft copper wires twisted together to ensure flexibility; the insulation layer is made of heat-resistant and oil-resistant elastomer materials to maintain stable electrical performance during long-term operation. The sheath is made of PVC or polyurethane formulations, with a smooth surface, balancing wear resistance and oil resistance. For outdoor applications, a UV-resistant formulation can be chosen. The flat structure requires high standards for the sheath molding process, ensuring that each core wire is neatly arranged and the sheath thickness is uniform, in order to avoid premature wear caused by locally thin areas.
From the perspective of the cable manufacturing process, the core of flat cables lies in parallel arrangement during cabling and extrusion molding of the sheath. The conductors are arranged in parallel at the designed spacing, maintaining uniform gaps between the cores to avoid mutual compression during operation; the sheath is extruded using a special flat-shaped mold, and after molding, the width and thickness tolerances are controlled to ensure stable operation of the cable in the guide trough. For elevator trailing cables, reinforcement cores (such as steel wire ropes or aramid ropes) can be added inside the cable cores to bear the tensile load of its own weight, preventing long-term sagging deformation. After cabling, a bending fatigue test needs to be conducted to verify the structural stability under high-frequency bending.
