Make the wire hollow? Shengda Electric helps China's generator industry to flourish

Have you ever seen hollow wires?

Generally speaking, solid wires are used when transmitting electrical energy with wires, so in the general perception of the public, wires
are solid.
However, in high-frequency lines, there is often a phenomenon called "skin effect", that is, the current is concentrated in the "skin" part of the conductor, if the hollow-shaped conductor is used, the power loss can be greatly reduced, saving the conductor material, so the hollow conductor came into being
.
In generators, hollow wires also act as cooling, taking away the heat
caused by cutting magnetic field lines.

Shengda Electric, a subsidiary of Far East Smart Energy Co.
, Ltd.
(hereinafter referred to as: Smart Energy Stock Code: 600869), specializes in the production of high-precision ultra-thin lithium battery copper foil, copper alloy contact wire for electrified railway, hollow conductor for large generator sets and silver and copper row and other products, in the field of hollow conductor for many years, with profound R & D and production strength, helped to build the Yangtze River Three Gorges hydropower station, Yangjiang, Fuqing, Hongyanhe and other nuclear power plant projects, is a designated supporting enterprise of large-scale generator factories at home and abroad
。

China's generator market has a promising future, and the demand for hollow conductors is strong

In recent years, the rapid development of the national economy has provided continuous impetus
for the steady and rapid development of China's power industry.
As one of the indispensable equipment of mechanical equipment, generators are widely used in agricultural machinery, automobiles, fire protection, communications, engineering construction and other industries
.
At the same time, generators have also entered thousands of households as a backup power source for many ordinary families, and market demand has increased
sharply.

According to the "China Generator and Generator Set Industry Market Outlook and Investment Strategic Planning Analysis Report Prospect", at the end of 2011, the generator and generator set manufacturing industry achieved sales revenue of 290.
069 billion yuan, and the average annual growth rate of sales revenue in the past five years was 47.
63%.

Hollow conductor is a coil and wire rod that can introduce cooling medium in the generator, which can take away the heat caused by cutting the magnetic field line and play a cooling role, which is one of the main components of the generator set, so the growth of generator shipments will continue to increase the market demand
for hollow wire.

Shengda Electric keeps a close eye on the market and aims at demand, and continues to promote the production, development and sales of hollow conductors for large-scale generator sets, helping China's generator industry to flourish.

Good product quality, stable operation in special environments

The production process of hollow conductor is complex, different types, and the production process is also completely different
.
Shengda Electric has domestic advanced production and testing equipment, such as optical spectrum analyzer, oxygen analyzer, metallographic microscope, digital resistance meter, withstand voltage meter, scratch resistant instrument, etc.
, which can meet the different production processes of copper hollow conductor and stainless steel hollow conductor, and high-precision testing instruments can strictly control product quality
.

Stainless steel hollow conductor Copper hollow wire

The copper hollow conductor produced by Shengda Electric is a special product for large and medium-sized generators at home and abroad, and can produce large-length copper hollow conductor according to user requirements, and needs to go through a series of processes such as semi-continuous ingot casting, hydroseal extrusion, drawing, annealing, and package insulation in the manufacturing process, with low oxygen content, high conductivity and good mechanical properties
.

In addition to copper hollow conductors, stainless steel hollow conductors are also one of the main products of
Shengda Electric.
Compared with copper hollow conductors, stainless steel hollow conductors need to go through ingots, extrusion, solid solution, drawing, solid solution and other processes, with strong corrosion resistance, low magnetic permeability, good mechanical properties and other characteristics, can be used in nuclear power and million-level generators, is the core component
of supercritical turbine generators and nuclear generators.

The products are used in large generator sets, and the use environment is complex and changeable, so the performance requirements for the conductor are extremely high
.
Before each batch of products into storage, it needs to go through layers of inspection, the inner and outer surfaces of the products should be clean, smooth, uniform, free of pollutants and inclusions, cracks, and the external dimensions, mechanical properties and electrical properties should also meet national standards
.
In addition, according to the requirements of the demand side, hydraulic resistance inspection, eddy current testing, oxygen content testing, etc
.
will also be carried out.

Quality management system certification

Shengda Electric has passed the IOS9001 quality system certification in 2001, and the perfect quality management system and high-precision production and testing equipment ensure the excellent performance
of Shengda Electric hollow conductor.

Adhere to the development concept of science and technology and further improve the research and development system

The core competitiveness of enterprises lies in technology
.
As a high-tech enterprise in Jiangsu Province and a national standardization good behavior enterprise, Shengda Electric has always adhered to the development concept of "revitalizing enterprises with science and technology", established a provincial fine copper alloy engineering technology research center, has dozens of invention patents, and won a number of Jiangsu Province Science and Technology Progress Awards, integrating the research and development, production and service of electrolytic copper foil, copper and copper alloy products
.

The company maintains long-term strategic cooperative relations with many domestic universities and institutes such as Shanghai Electric Cable Research Institute, Shanghai Jiao Tong University, and Railway Research Institute, and has established production, education and research bases to cultivate high-level talents that are more in line with the needs of enterprises and help enterprises achieve pioneering and innovation
.
At the same time, in order to improve the overall professional and technical level of the R&D team, Shengda Electric invests a lot of money, hires top experts with high salaries, strengthens the construction of the scientific research team, and further improves the R&D system
.

In terms of hollow conductors, Shengda Electric excavates market demand, puts forward higher requirements for the research and development of hollow conductors, actively seeks new breakthrough points, continuously improves product technology level, occupies technical highlands, expands the market share of hollow conductors for large-scale generator sets of Shengda Electric, and maintains market competitive advantage
.

In line with the business philosophy of "honesty and trustworthiness, customer satisfaction", "stable and reliable" product quality, and "continuous improvement" service commitment, Shengda Electric wholeheartedly provides high-quality products and services for customers at home and abroad!
