New derivative products of wires and cables
New derivative products of wires and cables are mainly produced by adopting new materials, special materials, changing product structure, improving process requirements, or combining different kinds of products due to different application occasions, application requirements, convenience of equipment and reducing equipment cost.
Different materials are used, such as flame retardant cable, low smoke halogen-free / low smoke low halogen cable, anti termite, anti mouse cable, oil / cold / temperature resistant cable, etc
Change the product structure, such as fire-resistant cable, and improve the process requirements, such as medical cable
Combined products such as OPGW;
Facilitate installation and reduce equipment cost, such as prefabricated branch cables.
Such as: high temperature resistant wire and cable
High temperature resistant wires and cables are required in aerospace locomotives and vehicles, energy, steel, non-ferrous metal smelting, oil mining, motors and other fields. High temperature resistant wires and cables with long-term continuous working temperature of 125 ℃, 135 ℃, 150 ℃, 180 ℃, 200 ℃, 250 ℃ and above, and commonly used wires and cables such as irradiated cross-linked polyolefin, silicone rubber, fluororesin, polyimide, mica and magnesium oxide. Now introduce; Two new high temperature resistant wires and cables.
1. Polyethersulfone (PES) insulated wire has excellent heat resistance, physical and mechanical properties, electrical insulation properties and extrusion formability. In particular, it can be used continuously at high temperature and maintain stable performance in the environment with rapid temperature changes. The thermal deformation temperature is 200-220 degrees, the continuous service temperature is 180-200 degrees, and the UL temperature index is 180 degrees; It can withstand 150-160 degrees of hot water or steam, and is not eroded by acid and alkali at high temperature: the elastic modulus is almost unchanged at 100-200 degrees, especially above 100 degrees, which is better than any thermoplastic resin; The coefficient of linear expansion is small, and its temperature dependence is also small; It is also approved by Japan's Ministry of health Announcement No. 434 and FDA, and is also non-toxic; It has self extinguishing property without adding any flame retardant. It has excellent flame retardancy and can reach UL94V-0 level (0.46mm).
2 polyether ether ketone (PEEK) insulated wire polyether ether ketone is a super heat-resistant thermoplastic resin. The long-term continuous use temperature is 250 degrees, and the UL temperature index is 250 degrees. Peek is a flexible resin with good creep resistance. And it has self extinguishing property. Without any flame retardant, it can meet the requirements of ul94v-1 (thickness: 0.3mm), 94V-0 (thickness: 1.5mm) and 94v-5 (thickness: 3.2mm).
Copper clad aluminum wire and cable
At present, the price of non-ferrous metals has soared, and the cost of copper conductor accounts for more than 90% of the total cost of cable materials. In order to not only meet the technical indicators of cable copper conductor, but also greatly reduce the cable cost, Shenghua Group Co., Ltd. independently developed the new copper-clad aluminum material technology according to the market demand and relying on the strong scientific and technological force of the group, and applied it in the wire and cable industry, formulated the enterprise standard, and the products passed the test of the national wire and cable quality supervision and inspection center. After being tried by many users, it has been highly praised by experts and users. We are actively expanding production scale to meet market demand.
