Product overview
The shell of Chinese box transformer is mainly made of cold-rolled steel plate (thickness 2.0mm). After anticorrosion treatment, the surface coating has strong adhesion and uniform color. The shell design not only has the functions of preventing condensation and mildew, but also can maintain good corrosion resistance in high temperature and high humidity environment. The shell material includes 50mm thick color steel plate, cold-rolled steel plate, etc., and imported topcoat with strong anti-corrosion ability is adopted to ensure structural stability and durability in various harsh environments. In addition, the design of Chinese box transformer shell also pays attention to aesthetics and practicality. The shell is packed with fireproof, anticorrosive and shockproof materials, with simple and beautiful appearance and compact structure, which can meet the needs of various places without losing beauty. The design of the shell has a certain radian, which improves the aesthetics and also enhances the structural strength. In terms of installation and maintenance, the shell design of Chinese box transformer is convenient for installation and debugging, and the internal equipment is modular design, which is very convenient for maintenance and can greatly improve the service life of box transformer.
Material selection
Stainless steel, cold-rolled steel plate, aluminum alloy, composite plate, etc., meet the corrosion resistance and strength requirements of different environments (such as high salt fog, cold and high temperature along the coast). Surface treatment: plastic spraying, zinc plating, baking paint, etc., to enhance corrosion resistance and aesthetics.
Size and structural design
Customize the length, width, height and internal partition according to the internal equipment layout (transformer, high and low voltage cabinet, etc.).
Optional modular design, convenient for transportation and quick assembly on site.
The protection grades
Standard IP23 (waterproof and dustproof), which can be upgraded to IP54 (splash-proof) or higher to adapt to harsh environment.
Special function customization
Ventilation and heat dissipation: shutters, forced exhaust system, temperature control fan.
Safety protection: explosion-proof design, anti-theft locks and fireproof materials.
Intelligent: sensor interface, remote monitoring module and lighting system are reserved.
Appearance design
Color customization (such as State Grid Green and RAL standard color cards), corporate logo spraying or mounting.
Terrain adaptation: slope top, flat top, double roof, etc., to meet special installation scenes.
Customization process
Demand communication
Customer provides project parameters: environmental conditions, equipment list, protection level, size limit, etc.
The technical team shall dock and confirm the design details (such as the position of cable entrance and exit and the size of access door).
Scheme design
3D drawing output, marking material, structure, opening position, etc., and signing the contract after the customer confirms.
Production-manufacturing
Laser cutting/bending → welding → surface treatment → assembly, and the whole process is controlled by ISO quality management system.
Production cycle: regular 15-25 days, expedited service can be negotiated.
Quality inspection and delivery
Conduct air tightness test and grounding resistance test before leaving the factory.
Support logistics and distribution to be present or guide on-site installation.
