With the development of the electric power industry, the requirements for supporting industries are becoming higher and higher, wire and cable as an important part of the power supporting industry, the same is no exception, facing the need to upgrade to meet the needs of power development. The future of wire and cable enterprises should improve technology, saving raw materials, the development of new environmentally friendly materials and other aspects of the effort.
Carbon fiber has been developing faster and faster in recent years, and there is a possibility that carbon fiber cable may replace traditional steel-core aluminum stranded wire in the future. Carbon fiber cable is an alternative to traditional steel-core aluminum stranded wire (bare wire) and is mainly used in 110kv~220kv lines. Compared with conventional steel-core aluminum conductor (ACSR), the aluminum cross-sectional area of ACCC is increased by 29%, while the weight per unit length is 20% lighter, thus the use of ACCC can greatly enhance the line transmission capacity and reduce losses under the condition that the allowable overhang is certain. By replacing a large number of ordinary conductors with ACCC conductors, power companies can achieve grid expansion without new lines, with significant savings in land, tower and engineering costs, in line with the policy direction of energy saving and efficiency. Carbon fiber composite conductors will be a revolutionary alternative to existing conductors. Thus for those in the field of carbon fiber composite wire has a strong competitive advantage of the enterprise to provide a new development opportunity.
Aluminum alloy cable conductivity and copper-core cable is comparable, its flexibility is better than copper-core cable, changing the previous pure aluminum cable mechanical strength is poor, low fatigue resistance, joints prone to accidents and other shortcomings, to protect the cable in the case of long overload and overheating cable connection continued stability, but also to make up for the traditional copper cable has a memory effect and high rebound performance and other defects, reducing the line loss It also compensates for the memory effect and high bounce performance of traditional copper cables, reducing wire loss.
In addition, whether from the production of raw materials, processing, manufacturing to transportation, installation, operation, recycling, all kinds of aspects, aluminum alloy cable compared to traditional copper-core cable, have incomparable economic and environmental advantages, will undoubtedly be the best alternative to copper cable, which is actually a good thing for the material heavy light wire and cable enterprises.
With the emergence of environmental pollution such as haze, people today are paying more and more attention to environmental protection, the wire and cable industry is no exception, is bound to face the requirements for environmental protection. Wire and cable industry, environmental protection mainly refers to the material environmental protection. At present, the production of wire and cable use a large number of rubber, PVC, polyethylene and other polymer chemical materials. In the production process produces a large number of toxic and harmful gases. Therefore, to actively develop environmentally friendly materials, the production of environmentally friendly wire and cable. After developing environmentally friendly wire and cable, cable companies such as Fujikura in Japan have actively promoted the government to enact environmentally friendly wire and cable product standards in order to monopolize the market. In recent years, the share of sales of environmentally friendly wire and cable has expanded dramatically, and ordinary wire and cable and flame retardant wire and cable simply cannot compete with them. In addition, in the wire and cable production process generated by the edge of the residue, can be directly recycled.
From the installation of wire and cable, also facing a new development trend, that is, thin sheath, cross-section miniaturization. Given the ease of installation, use and transportation, while reducing the cost of raw materials as much as possible, wire and cable products increasingly have a tendency to develop, that is, cable development for a thinner sheath, smaller cross-section, while ensuring that the flow rate. This requires an integrated wire and cable industry technology compared to the previous ones.
