Application
Widely used in fields such as rail transit, aerospace, new energy, military, power, petrochemicals, etc.

Rail transit

A transformer is a device that transforms alternating voltage, current, and impedance. When an alternating current flows through the primary winding, an alternating magnetic flux is generated in the core (or magnetic core), inducing a voltage (or current) in the secondary winding. A transformer consists of a core (or magnetic core) and windings; the windings comprise two or more coils, with the coil connected to the power supply referred to as the primary winding and the remaining coils as the secondary windings.

Wind power generation

Wind power generation refers to the conversion of wind’s kinetic energy into electrical energy. Wind energy is a clean, pollution-free, renewable resource that has been harnessed by humans for centuries, primarily through windmills used for pumping water and grinding grain. Today, however, the focus has shifted to generating electricity from wind. Wind power is highly environmentally friendly, and given the vast potential of wind resources, it is receiving increasing attention from countries around the world.

Nuclear and hydro power

Both the fusion of light atomic nuclei and the fission of heavy atomic nuclei release energy, known as fusion energy and fission energy, respectively. During these processes, substantial amounts of heat are generated, and the energy is subsequently converted through nuclear energy–mechanical energy–electrical energy pathways, resulting in electricity that is referred to as nuclear power. Hydropower is a clean energy source: it is renewable, pollution-free, has low operating costs, facilitates peak-shaving in power supply, and helps enhance resource utilization and overall economic and social benefits.

National Defense Industry

The defense industry, also known as the military industry, is an industrial sector that serves national defense construction and directly provides weapons and equipment to the armed forces. Its primary output includes weaponry and military hardware, logistical support vehicles and supplies for defense transportation, reconnaissance systems, and military communications and command-and-control systems; it may also encompass the provision of logistical supplies and equipment to the armed forces as well as related enterprise operations. The defense industry is a robust pillar of national security and peace.

New energy vehicles

New-energy vehicles encompass four main categories: hybrid electric vehicles (HEVs), battery electric vehicles (BEVs)—including solar-powered vehicles—fuel-cell electric vehicles (FCEVs), and other new-energy vehicles that utilize high-efficiency energy-storage devices such as supercapacitors and flywheels. Non-conventional automotive fuels refer to fuels other than gasoline and diesel.
