2. w ap itilize segondè ak presizyon boul plimen baton pou ranplase orijinal aliminyòm plimen baton, ki fè chasi stab tankou fè, ap fè antre, ak pwèske pa autorisation pandan transmisyon. Boul baton plimen gen ti mouvman rezistans, jistès anwo nan syèl la ak wo kote yo pote kapasite. Li résout pwoblèm sa lè pouse VCB ki anwo nan syèl la kouran yo nan yon électrique, chasi la ka fè defigire an ba entansite plimen baton.

2. Using high-precision ball screw rod to replace original aluminum screw rod, which make chassis is stable as moving in and out, and nearly no clearance during transmission. The ball screw rod has small movement resistance, high accuracy and high bearing capacity. It solves the problem that when pushing VCB of high current into a switchgear, the chassis may be distort due to low intensity of screw rod.
