Wall Bushing

Detailed Description
Wall Bushing Series, Butt joint bushing 254 (cable branch box) with rated voltage 12kV, withstand voltage 45kV, capacitance 18 ± 2pF, red color, and 2-M4.

Technical Specifications

The Technical Specifications of this Wall Bushing define its core electrical and mechanical parameters for proper system integration. The rated voltage of 12kV establishes the maximum continuous operating voltage for this Butt joint bushing 254, while the withstand voltage of 45kV confirms its impulse insulation capability per standard test procedures. The capacitance value of 18 ± 2pF is a critical Technical Specification that influences the capacitive grading along the bushing surface, directly affecting the voltage distribution when this Switchgear Insulation Component is installed in a cable branch box. The red color specified in the Technical Specifications serves not only aesthetic purposes but also practical phase identification in multi-phase assemblies. The 2-M4 thread specification denotes the mounting interface dimension, ensuring compatibility with standard hardware. Each Technical Specification parameter—voltage, capacitance, color, and thread size—has been validated through routine production testing to guarantee that every Switchgear Insulation Component meets the stated values. Adherence to these Technical Specifications ensures that this Wall Bushing performs reliably as a Switchgear Insulation Component within its designated 12kV switchgear application.
