Large floor area, spacious space. Full personnel and equipment must be provided. To save construction time and rationally divide the construction area, the installation of the main and auxiliary structures of the workshop and the installation of the enclosure structures are carried out in an interlocking manner, making construction cooperation particularly important.
The multi-layer cranes installed in the factory's workshop demand high precision in the steel structure installation, and strict quality control must be enhanced during the construction of the high-voltage shielding halls. When hoisting large-section H-shaped steel trusses, how to maintain plane stability without deformation?
The construction of concrete-filled steel tubular columns requires dense grouting, and appropriate construction methods should be adopted to ensure construction quality.
The high-voltage test room is equipped with six-sided shielding, reducing the shielding efficiency of the partial discharge high-voltage shielding hall by 65 dB, with a frequency range from 0.5 to 1.6 MHz. Due to the high shielding requirements and large area, quality control is crucial during construction.
Currently, the new energy vehicle industry is in an exploratory phase and is in the trial production stage. There is no industrial scale at home and abroad, so the related components are also in the trial production stage. However, compared with the overall technical level of automotive wiring harnesses, China's harness assembly mainly lags behind in the assembly of automotive harnesses. Foreign automotive harness technologies have a solid foundation, and solutions have been found for high-voltage harnesses.
To prevent interference from external signals, electrostatic shielding is extensively used in the shielding high-voltage surge arrestor hall during scientific and technological work. Many electronic instruments are covered with metal lids. Communication cables are sheathed in lead; high-voltage operators wear metal mesh; for instance, telephone lines pass under high-voltage lines. To prevent the influence of high-voltage lines on telephone lines, a metal mesh is installed between them. These are all shielding measures to prevent external electric field interference.

Prevent Electrostatic Shielding
Electrostatic shielding can also have adverse effects, such as in high-voltage shielded halls, where communication devices in steel structures receive weaker signals; when spacecraft re-enter the Earth's atmosphere, they experience high-speed friction, forming a plasma layer around the spacecraft and creating a static shielding effect on the spacecraft, which temporarily interrupts communication between the spacecraft and the ground control center.
