Comprehensive Medium Voltage Support: Liyond provides a robust selection of contact boxes engineered for primary medium-voltage systems, covering 12kV, 24kV, and 40.5kV ratings.

Scalable Current Solutions: Our product line is designed to handle diverse electrical loads, with rated currents covering the full spectrum from 630A up to 4000A.

Diverse Shapes for Precision Fitting: We offer contact boxes in various external shapes and structural configurations, with detailed engineering drawings available to verify mounting hole sizes and overall dimensions for a perfect match with your switchgear layout.

Optimized Thermal Performance: Each unit, whether for a 12kV/630A distribution board or a 40.5kV/3150A industrial switchgear, is precision-molded to ensure stable heat dissipation and exceptional dielectric strength.

Application-Specific Excellence: From compact 12kV solutions to heavy-duty 40.5kV components for KYN61 cabinets, our products are optimized to balance high-performance insulation with your specific spatial constraints.

High-Precision Switchgear Contact Boxes by Advanced APG Technology

Liyond utilizes the Automatic Pressure Gelation (APG) technique to ensure our contact boxes possess superior structural integrity and dimensional accuracy. While sharing manufacturing processes with other insulation components, our epoxy resin contact boxes are specifically optimized for their unique functional role:

High Dimensional Precision: The casting process is fine-tuned to ensure a perfect interface with vacuum circuit breaker contacts, minimizing mechanical misalignment.

Homogeneous Insulation: Advanced vacuum processing ensures a dense, void-free structure, providing stable dielectric strength for 12kV, 24kV, and 40.5kV medium voltage switchgear.

Enhanced Creepage Path: The skirt design is engineered to maximize the creepage distance, effectively preventing surface flashover in the narrow confines of a switchgear cabinet.

By tailoring our APG process to the specific geometry of spout insulators, we deliver products that maintain high insulation reliability under continuous electrical and thermal stress.
