Liyond Switchgear Contact Box Series for High-Performance Insulation and Connection

Liyond Electric Contact Box series provides essential insulation for medium-voltage switchgear like the KYN28. As a professional contact box supplier, we offer high-dielectric housing solutions that secure the connection between vacuum circuit breakers and busbar systems, ensuring safe power transition and preventing flashovers in systems from 12kV to 40.5kV.

Core Design and Safety Features

Liyond's series of contact box and spout insulator prioritize reliability through advanced materials and compact design:

• Advanced APG Casting: Utilizing Automatic Pressure Gelation (APG) with high-grade epoxy resin ensures a void-free structure with superior mechanical and thermal stability.

• Superior Insulation: High creepage distance and dielectric strength protect against phase-to-phase and ground flashovers, even in polluted or humid environments.

• Mechanical Durability: Engineered to withstand the stress of frequent circuit breaker operations while maintaining precise contact alignment.

• Versatile Solutions: Available in multiple configurations (flat, round, or bell-mouth) to ensure seamless compatibility with diverse switchgear architectures.

Ordering Information

To ensure the accurate selection of the Liyond Contact Box for your medium voltage switchgear, please provide the following technical details:

1. System Ratings: Specify the rated voltage (e.g., 12kV, 24kV, 40.5kV) and the rated current (e.g., 630A, 1250A, 3150A).

2. Mounting Dimensions: Provide the installation hole spacing and the diameter of the mounting flange to ensure a perfect fit with the cabinet partition.

3. Internal Diameter: Confirm the inner diameter required to accommodate your specific fixed contact and contact arm assembly.

4. Specific Model or Drawing: Due to the variety of switchgear designs, providing a model number (e.g., CH3 series) or a technical drawing is highly recommended for verification.

5. Environmental Requirements: Mention if the application requires enhanced creepage distance for high-pollution or high-altitude areas.
