high-voltageswitchgear process for 110kv

high-voltageswitchgear process for 110kv

It uses a gas mix similar to the air we breathe, made up of nitrogen (80%) and oxygen (20%), as a carbon free alternative to SF6 which has traditionally been the method of insulation in high voltage switchgear since the 1960s. The chemical properties of SF6 gas make it ideal for electrical insulation and arc quenching in high-voltage switchgear.

  • Bushing (electrical) - Wikipedia

    Explanation. All materials carrying an electric charge generate an electric field.When an energized conductor is near a material at earth potential, it can form very high field strengths, especially where the field lines are forced to curve sharply around the earthed material. The bushing controls the shape and strength of the field and reduces the electrical stresses in the insulating material.
