Our Contribution to the LV Switchgear Industry

Solving Critical Challenges

Primary moving and fixed connectors (also known as main circuit connectors or primary disconnects) are the key components that connect the main power circuit between the drawout unit and the fixed part of a low‑voltage drawout switchgear.

Innovative Plug-in primary Connectors for Higher Safety and Reliability

Low‑voltage drawout switchgear faces two persistent challenges: excessive temperature rise and unstable contact resistance in primary connectors. Overheating can lead to insulation failure, arc faults, and even unplanned outages – a major risk for power distribution systems.

Our patented composite laminated plug‑in type primary connectors (CN201038641Y) and advanced plug‑in connector (CN201898227U) directly address these  issues:

Our Contribution to the LV Switchgear Industry – Solving Critical Challenges

Key Solutions

Enhanced heat dissipation – Convex points between laminated contacts create ventilation gaps, increasing surface area and airflow. The housing is designed with cooling slots to keep temperature rise under control.

Non‑magnetic stainless steel springs – Eliminate self‑induced thermal magnetic fields, reducing heat generation and improving long‑term reliability.

Precise contact alignment – Fixed clamping and locating structures ensure consistent insertion force and low contact resistance, preventing poor connections.

Modular, tool‑free assembly – Simplified fixing mechanism inside the connector housing maximizes internal space for cooling while allowing easy installation and maintenance.

Our Contribution to the LV Switchgear Industry – Solving Critical Challenges

Industry Contribution

These innovations have become industry benchmarks. Our connectors are widely adopted in  drawout switchgear systems, significantly improving operational safety and reducing downtime. By solving the “overheating” bottleneck, we help panel builders and end‑users achieve:

Lower failure rates in high‑density drawer compartments

Extended component life under continuous full‑load operation

Compliance with stringent IEC 61439 temperature‑rise tests

Our Contribution to the LV Switchgear Industry – Solving Critical Challenges
