DJG-7 Series Hand-Cranked Mechanism Applied in Data Center LV Drawer Switchgear

Deyuan Electric’s independently developed DJG-7 Series Hand-Cranked Mechanism (for Unit Drawer) has been successfully applied in the Huawei Data Center Project, providing efficient and reliable operating solutions for drawer units in data center low-voltage power distribution systems.

Huawei Data Center is a world-class digital infrastructure project, demanding exceptionally high standards for power supply continuity, reliability, and maintainability. In data center low-voltage distribution systems, the drawer insertion mechanism is a critical component that ensures safe operation and stable performance of each drawer unit.

Deyuan Electric Solution

The DJG-7 Series Hand-Cranked Mechanism used in this project is a high-performance drawer operating mechanism developed by Deyuan Electric specifically for unit drawers, featuring the following technical characteristics:

Feature Specification

Double-Head Screw Structure Made of high-strength, wear-resistant engineering plastic, suitable for drawer units requiring high operating force—saves 50% operating effort compared to conventional mechanisms.

Three-Position Indication Text display for Connect, Test, and Drawout positions, with audible tone confirmation

Electric Operation Option Independent single-pole double-throw switch available at both TEST and WORK positions for remote control capability

Precise Travel Distance 24mm travel from TEST position to WORK position ensures accurate engagement

Limit Guide Rail Option Optional limit guide rail improves drawer positioning accuracy and reduces insertion/withdrawal difficulties caused by mechanism mounting plate deformation

Customer Value

In the Huawei Data Center Project, the DJG-7 Series Hand-Cranked Mechanism delivered the following core values:

Effortless Operation: The double-head screw structure reduces operating force by 50% compared to conventional mechanisms, significantly improving operator experience during routine maintenance

Clear Position Indication: Triple confirmation with text display, audible tone, and optional LED lighting ensures drawer position is unmistakable, preventing operational errors

High Reliability: High-strength wear-resistant engineering plastic construction withstands frequent operation cycles required in data center environments

Precise Engagement: 24mm precision travel, combined with optional limit guide rail, ensures accurate alignment between drawer and cabinet primary connectors

Flexible Expansion: Optional electric operation capability supports remote control, meeting the intelligent management requirements of modern data centers
