Basic issues of reel cables

In addition to electrical properties, weather resistance, and other basic requirements that can be matched with the equipment, the reel cable has the following main characteristics: it can withstand long-time bending motion, extremely excellent tensile properties, pressure resistance, especially roll-over pressure resistance and resistance The superiority of the grinding characteristics is currently very low among manufacturers that can understand what is called "rolling pressure". Since the working principle of the reel is rotation, take-up, and pay-off, the reel itself is generally constant tension retractable and has higher requirements for the tensile strength of the cable, and the rewinding cable is laminated in a single layer or in multiple layers. The resistance of the cable itself to extrusion is better, and the deformation of the cable core caused by the extrusion is inevitable. The problem is that all the deformations have to be minimized to minimize the influence of the cable. The basic problem of the current reel cable is that the core is broken and Sheath cracking and tensile rope breakage insulation caused cable work to stop. Therefore, the flexibility of the conductor material of the reel cable, the tensile aging of the insulating material, the combination of the cores, the collocation of the auxiliary materials, the protection of the winding or the inner sheath, the requirements of the shielding, and the materials and requirements of the outer sheath, These are fundamentally different from general flexible cables.

At present, there are more than 6,000 enterprises in the country's wire and cable industry. China is already a wire and cable manufacturing country and a country where wire and cable consumption in the world has grown rapidly. However, the level of wire and cable per capita consumption is about one-fifth that of developed countries. The future market demand for wire and cable still has great room for growth. In the coming years, the smart grid, nuclear power, railways, airports, construction, home appliances and other industries will flourish, and the demand for wire and cable products will also grow rapidly.

The reel cable is also known as the 'reel cable'. The product is produced by Shanghai Mingnai Special Cable Co., Ltd. It is characterized by wear resistance, oil resistance, and tear resistance. Reel cables for mobile devices such as fast-moving container cranes, lifting gears for mobile devices such as fast-moving container cranes, lifting equipment, large underground vehicles for excavation and underground excavation equipment, large underground vehicles for excavation, and underground mining equipment for excavators. , can be used in large-scale and excavator ground underground mining and other occasions with high mechanical stress.
