Product quality is not only related to the safe operation of the power grid, but also related to personal and property safety. As early as 1986, the relevant departments of the State Council included electric power fittings products into the management of production licenses. The production license unit of power fittings products is divided into malleable cast iron, forging, aluminum, copper and aluminum, and cast iron. According to the role played by the product, it is usually divided into 9 categories, including suspension clamps, strain clamps, connection fittings, connection fittings, protection fittings, pull wire fittings, equipment clamps, T-shaped clamps, and fixed fittings. Transmission and transformation projects of various voltage levels.
The future development trend of electric power fittings products is mainly in energy-saving fittings products for power transmission and transformation lines and distribution lines above 500KV. Such as: aluminum alloy suspension clamps, pre-twisted power fittings, damping spacers, equalizing rings, energy-saving shock-proof hammers and new non-magnetic materials instead of ferromagnetic materials to make ordinary fittings and energy-saving. All power fittings manufacturers have to continuously increase equipment investment, adopt advanced technology, improve product quality, and enhance market competitiveness.
Iron or aluminum metal accessories widely used for wires are collectively referred to as fittings. Most of the fittings need to withstand greater pulling force during operation, and some have to ensure good electrical contact at the same time.
There are many types of fittings and different uses, such as various wire clamps for installing wires, various hanging loops forming insulator strings, various crimping tubes and repairing tubes for connecting wires, and various types of spacers on split wires. In addition, there are various types of pull wire fittings used for poles and towers, as well as the size of the protective conductors, which must be matched with each other. It is related to the safety of wires or towers, even if one is damaged, it may cause line failure. Therefore, the quality, correct use and installation of fittings have a certain impact on the safe power transmission of power transmission lines.
1. According to the function and structure, it can be divided into suspension clamps, strain clamps, connection fittings, connection fittings, protection fittings, equipment clamps, T-type clamps, bus fittings, pull wire fittings, etc.; it can be used as line fittings according to purpose And substation fittings.
2. According to the product unit of power fittings, it is divided into malleable cast iron, forging, aluminum, copper and aluminum, and cast iron, with a total of four units.
3. It can also be divided into national standard and non-national standard
4. According to the main performance and purpose of fittings, fittings can be divided into different types.

Even if one is damaged, it may cause a line failure. Therefore, the quality, correct use and installation of fittings have a certain impact on the safe power transmission of the line.
With the rapid development of our country, the role of household hardware accessories in furniture has become more and more important. Consumers’ attention to the quality of household products has also gradually shifted from sheet materials and environmental protection to hardware accessories. Traditional domestic home furnishing products originally do not require sliding rails for hardware accessories, and basically all functions are realized on the basis of wooden structures.
Domestic home hardware accessories should pay attention to innovation and quality
In recent years, the price of raw materials has continued to rise. The increase in labor costs and logistics costs, and the financial crisis have become the main factors restricting the development of domestic and foreign sales of the domestic home hardware industry. The rapid development of the customized home furnishing industry also objectively requires the home hardware industry to comply. The trend of the times, combined with the market situation, attaches importance to product quality and innovation. In this case, if the home hardware industry wants to continue to move forward, transformation and upgrading are the key to solving the problem.
Home hardware accessories promote enterprise transformation and upgrading
As one of the important production bases of domestic hardware, it is constantly enhancing the power of scientific and technological innovation and accelerating the process of industrial adjustment and upgrading to explore new models of regional development in order to promote the transformation and upgrading of cities and industries.
According to Junji Hardware: In the past, when it comes to home hardware manufacturing, many domestic customers will think of resistance, but home hardware accessories make people shine. In fact, some excellent domestic hardware manufacturing enterprises have already possessed the technical level comparable to foreign ones, but in the division of labor in the international market, domestic household hardware enterprises and even the entire hardware industry still play the role of lower-level producers and processors. At present, there are 800 household hardware and spare parts manufacturing enterprises in the area, including 16 enterprises with an annual output value of more than 100 million yuan, 200 enterprises above designated size, 10 national high-tech enterprises, and 50 private technology enterprises in Guangdong Province. , 15 companies became United Nations registered suppliers. In addition, the home hardware industry in the building materials industry has 10 scientific research and development centers, 1 product testing center, 3 well-known trademarks in Guangdong Province, 6 provincial-level brand-name products, and 4 provincial-level key export brands to cultivate and develop.
Industry insiders said that the household products industry should take this as an opportunity to stand on the global industrial chain and continue to promote the transformation and upgrading of enterprises. Many companies in the household products industry are family-owned businesses. Only if they can endure loneliness and insist on making their own brands, future generations will not only work for foreign brands. In the near future, household hardware accessories will become the most critical factor in the overall quality of household products. With the development trend of modernization and individualization of domestic home hardware accessories, the home hardware industry developed in a group will become the driving engine for the upgrading and transformation of home hardware accessories in the future. The above is an introduction to domestic home hardware accessories that should pay attention to innovation and quality.
