Military-grade cable
This invention pertains to the field of wire and cable technology and discloses a long-lasting wire cable featuring a nanocoating. The cable includes a nano-oxidation-resistant layer. By incorporating a nano-oxidation-resistant layer, a fire-retardant layer, an anti-corrosion layer, and a shielding layer, this innovative cable is equipped with robust external protection capabilities. Additionally, an anti-corrosion layer is strategically placed inside the fire-retardant layer, enhancing the cable's overall corrosion resistance and significantly boosting its ability to withstand corrosive environments. On the outer side of the fire-retardant layer, a tightly adhered nano-oxidation-resistant layer—crafted from nano-sized aluminum hydroxide—is applied, effectively enveloping the surface of the fire-retardant layer. This unique design not only improves the cable's overall antioxidant properties but also substantially extends its service life. Furthermore, heat dissipation is optimized through the integration of Heat Dissipation Holes 1 and 2, which facilitate rapid removal of heat generated on the core wires' surfaces. To ensure mechanical integrity, the cable is reinforced with a tensile-resistant cord, tear-resistant threads, and an inner cushioning layer. Finally, a U-shaped spring clip is positioned externally to this inner cushioning layer, providing additional protection that prevents the core wires from being compressed or torn under stress.

Solar photovoltaic cable
This utility model relates to the field of cables and introduces a solar photovoltaic cable comprising, from inside to outside: a conductor, an insulation layer, and a jacket. The insulation layer is equipped with numerous tiny holes, while the jacket incorporates an embedded metal skeleton. Specifically, the jacket consists of three layers arranged sequentially— an inner first jacket layer, an intermediate second jacket layer, and an outer third jacket layer— with the metal skeleton seamlessly integrated into all three layers. By designing the jacket as a multi-layer structure, this utility model effectively addresses diverse requirements such as high-temperature resistance and cold-resistance. Additionally, the internal metal skeleton significantly enhances the cable's ability to withstand external impacts. To counteract the weight of the metal skeleton, the insulation layer features countless perforations that not only reduce the overall weight of the cable, ensuring its reliable performance, but also enhance the insulation layer's impact resistance, thereby providing superior protection for the internal conductor.
Manufacturing cables
This utility model relates to the field of packaging and introduces a cable-drawing device designed for cable production. The device comprises a base plate, supporting columns, a top plate, a wire-supporting rod, and a counterweight structure. The base plate is positioned opposite the top plate, with the supporting columns securely fixed to both the base and the top plates. The wire-supporting rod passes through the top plate and is housed within the supporting columns. The counterweight structure consists of a connecting rod and a counterweight block. The connecting rod is vertically mounted on the wire-supporting rod, with the counterweight block firmly attached to the outer end of the connecting rod. One end of the connecting rod features a first wire-passing hole, while the top of the wire-supporting rod includes a second wire-passing hole. This utility model allows the copper wire roller to be easily installed onto the cable-drawing device, which itself has a substantial weight, effectively preventing it from tipping over during operation. Additionally, the device incorporates a counterweight mechanism that helps counteract centrifugal forces, ensuring stability even under high-speed conditions and providing reliable support for continuous copper wire delivery. Notably, the supporting columns in this design are constructed with an outer cylinder and an inner cylinder capable of relative rotation; as the copper wire is fed through, the inner cylinder rotates along with the wire, significantly reducing the risk of tangling.
