Liyond Insulating Bushing for Switchgear MV/HV

Insulating bushings are fundamental components in all medium and high-voltage power equipment, including switchgear, transformers, circuit breakers, and busbar systems. Liyond's epoxy resin cast bushing is engineered to perform two critical functions simultaneously: providing reliable electrical isolation between a conductor and its enclosure, and offering robust mechanical support for primary conductors.

Advanced Design, Versatility, and Applications

As one of the leading electrical switchgear manufacturers, Liyond's bushings are manufactured using advanced APG (Automatic Pressure Gelation) cast epoxy resin technology. This material delivers exceptional dielectric strength and mechanical durability, making the bushings extremely tough and resistant to impact, vibration, and environmental contamination. The result is a compact component that provides reliable high-voltage isolation and robust structural support.

Our versatile product range is essential for critical applications across the power system, including guiding conductors through Switchgear enclosures, providing mounting and isolation for circuit breaker components, and ensuring the secure sealing and insulation in instrument transformer product line and cable terminations. Liyond bushings guarantee reliable isolation and a long service life in these demanding applications.

Selection and Ordering Information

To select the correct insulating bushing for your application, please confirm the following critical parameters when placing an order:

1. Rated Voltage (kV): Specify the system voltage the bushing must isolate (e.g., 12 kV, 24 kV, 40.5 kV).

2. Rated Current (A): The maximum continuous current the conductor passing through the bushing will carry.

3. Application Type: Indicate the equipment the bushing is connecting (e.g., busbar support, vacuum interrupter mounting, wall through-bushing).

4. Dimensions and Drawing: Provide the required mechanical dimensions, including overall length, flange size, and mounting hole configuration, often best supplied via a technical drawing.
