Technical Specifications

The Technical Specifications of this Environmental Cabinet Accessories product define its electrical performance and dimensional parameters for medium-voltage switchgear applications. The rated voltage of 12kV and withstand voltage of 45kV establish the dielectric strength of this EX259 Bushing, while the partial discharge level of 15kV ≤ 3pC ensures superior insulation quality with minimal internal defects. The capacitance value of 18 ± 2pF contributes to uniform electric field distribution along the bushing surface. This EX259 Bushing features a red-colored housing that facilitates phase identification in multi-phase switchgear assemblies. The dimensional specifications of this Environmental Cabinet Accessories component—304.5, 259.5, 122.5, 91.5, and 3.8—define the critical mounting and clearance interfaces for proper cabinet integration. As a certified Switchgear Insulation Component, this EX259 Bushing is specifically designed for environmental cabinet installations, providing reliable electrical insulation between cable terminations and switchgear compartments. Each Switchgear Insulation Component undergoes routine partial discharge, capacitance, and high-voltage testing to verify compliance. Proper installation of this Environmental Cabinet Accessories bushing as a Switchgear Insulation Component ensures long-term reliability in 12kV indoor distribution networks.
