Product Introduction
The POWGRID-S series three-cabinet products are low-voltage complete sets specially developed by Chint Electric for the three-cabinet market. Their standardized product design, unified brand image presentation, and comprehensive enhancement of customer experience all stem from our original commitment to creating value for our customers.
Product Features
▷ Door-positioning mechanism: When the cabinet door is opened, the door-limiting mechanism effectively prevents the door from swinging open and colliding with operations and maintenance personnel.
▷ Doorway lighting: Convenient for inspection and maintenance in environments with poor natural light, eliminating the need for additional lighting.
▷ Folder: A folder is installed on the inside of the box door, allowing you to store documents such as product drawings, samples, and technical data for easy access at any time.
▷ Transport base: The transport base facilitates transportation when no lifting equipment is available on site.
▷ Foam seal: Compared to traditional sealing strips, the one-piece foam seal boasts high elasticity, seamless construction, and superior sealing performance, enabling true IP54-rated protection.
▷ Pre-assembled installation: The mounting brackets and crossbeams for pre-assembled mounting holes facilitate the positioning, adjustment, and securement of components and cables.
▷ High-quality surface finish: Wall-mounted type: Body 1.2mm, door panel: 1.5mm
Floor-standing: Shell 1.5mm, door panel: 2.0mm.
▷ “Say No to Awe-Inspiring Coolness”: Product design adheres to the principle of “easy processing,” eliminating the need for specialized equipment or special processes.
