Background

As is well known, the types of ferrous metal smelting rolled products are very many, the black metal smelting rolled products are a relatively mature application field, for example, which types of steel pipes are used in various industries, meanwhile, power cable cables are also used in various industries, such as power systems, information transmission, instrument systems and the like, the traditional cables and the steel pipes have no intersection, armoring is used when the ordinary cables need to be protected, a mechanical protective layer of the armoring cables can be added to the cables with any structures, the mechanical strength of the cables is increased, the anti-corrosion capability is improved, and the black metal smelting rolled products are wire cables designed for areas which are easy to be mechanically damaged and are easy to be corroded. The device can be laid in any mode, and is more suitable for direct burial laying in rock areas. The armored cable is generally a fixed power cable, in popular terms, the armored cable is fixed in a place and basically does not move, and a power line transmits electric energy. Besides the purposes of adding the armor layer to the cable, the cable can also enhance the mechanical protection such as tensile strength and compressive strength and prolong the service life. The armor has certain anti external force performance, can also carry and prevent that the mouse from stinging, is unlikely to see through the armor and causes the power transmission problem, and the bend radius of armor will be big, and the armor can ground connection, protection cable. The existing armored cable has a very simple structure, and the compressive strength of the armored cable cannot meet the requirement when the armored cable is used in some high-requirement occasions, so that the armored cable needs to be improved and is improved by combining a seamless steel pipe structure.
