Wall Bushing

Detailed Description
Feed-through bushing 281 (integrated with umbrella skirt) with rated voltage 12kV, withstand voltage 45kV, capacitance 18 ± 2pF, and red color.

Technical Specifications

The Technical Specifications of this Wall Bushing define its electrical parameters and mechanical configuration for medium-voltage feed-through applications. The rated voltage of 12kV and withstand voltage of 45kV establish the dielectric strength of this Feed-through bushing 281, while the capacitance value of 18 ± 2pF ensures uniform electric field distribution along the bushing surface. This Wall Bushing is designed with an integrated umbrella skirt that provides extended creepage distance, enhancing the surface insulation performance in polluted or humid environments. The red-colored housing of this Feed-through bushing 281 facilitates phase identification in multi-phase switchgear assemblies. As a certified Switchgear Insulation Component, this Wall Bushing serves as a reliable interface between cable terminations and switchgear compartments in 12kV indoor distribution networks. The integrated umbrella skirt of this Feed-through bushing 281 also improves self-cleaning properties under outdoor exposure. Each Switchgear Insulation Component produced undergoes routine high-voltage and capacitance testing to verify compliance with stated specifications. Proper installation of this Wall Bushing as a Switchgear Insulation Component ensures optimal dielectric performance and long-term service reliability in power distribution systems.
