With the accelerated pace of energy interconnection, the planning and construction of UHV is getting better and better. As an insulator that plays an important role in overhead transmission lines, the significance in the field of high-end power equipment manufacturing is self-evident. To this end, electrical manufacturing companies have promoted the development of the insulator industry from extensive manufacturing to intelligent manufacturing, and promoted the structural adjustment of the insulator manufacturing industry, from high energy consumption, labor-intensive, to low-energy, intelligent equipment.
Glass insulator into the main force of UHV lines
According to different production processes, insulator products currently used in the market include composite insulators, glass insulators, porcelain insulators, and the like. The glass insulator insulating member is composed of a glass fiber resin core rod (or a core tube) and a sheath of an organic material and an umbrella skirt. The utility model has the advantages of small size, light weight, high tensile strength, excellent anti-pollution and flashover performance.
There are relatively many glass insulators applied on China's DC and AC UHV lines. Domestic enterprises have achieved independent innovation through years of technical reserves and experience accumulation, and glass insulator products have significant advantages. First, the strength is higher, second, the anti-pollution ability is stronger, and third, the self-explosion rate is low. This feature eliminates the need for [zero value" detection of the glass insulator during operation, ensuring safe operation of the grid.
In recent years, China's power industry has developed rapidly, and the installed capacity of generators has increased year by year. As an indispensable part of power transmission and transformation equipment, insulators are inseparable from the development of the power industry.
Meeting new opportunities in the insulator market
According to the statistics of relevant departments, since 2004, the main business income of major enterprises in China's insulator industry has continued to grow rapidly. With the improvement of the technical level of China's insulation products manufacturing industry and the accelerated economic development of countries such as East Asia and South Asia, major domestic enterprises Seize the opportunity and actively explore the international market, the export delivery value of the industry has increased year by year.
The power industry is the most important application market for insulator arrester products. The launch of many power projects in China at present has not only provided a broad market space for the development of the insulator arrester industry, but also put forward new requirements for the industry product market and promoted The adjustment of the market structure of insulator arrester products and the research and development of new technologies.
Insulators are mainly used in the power grid field. The construction of [smart grid" will bring huge development opportunities for the insulator industry. First, a large amount of investment will provide a broad market space for the industry. Secondly, the upgrading of power grid construction will help the industry to optimize and integrate, form a new competitive landscape, and guide companies with new technologies, new materials and new products to obtain more. Large market space, so that there are more resources to support technological innovation, continue to drive industry upgrades and progress. The large-scale investment in power grid construction provides a fundamental guarantee for the development of the insulator industry. In addition, the construction of electrified railways and the continuous expansion of overseas markets have also provided new market opportunities for the insulator industry.
Based on the development level of the global power industry and investment planning, experts predict that the overall demand of the global insulator industry will maintain steady growth. Due to the continuous improvement of the reliability and economic requirements for the insulation of substations and overhead transmission lines, more insulator manufacturers will continue to invest in R&D around customer needs and continue to advance the industry.
