Functions

■ Eliminate short-circuit faults caused by small animals such as mice and snakes

■ Prevent acid, alkali, salt and other chemicals from corroding the busbar

■ Prevent maintenance personnel from accidentally entering the charging gap and causing accidental injury

■ Adapt to the development trend of miniaturization of switchgear

■ Solve the problem of phase insulation between busbars
