分岔母线
　　分支电流≥250A以上采用分岔母线与插接开关箱连接，可保证面接触的效果，更为安全。
Gratined Buses
When the current of branch is more than 250A,we can connect the grained buses with the jack switch box.ao we can ensure the surface contact more secure.

插接箱
　　插接开关箱内装自动空气开关（型号可根据用户选择）确保分路过载，短路保护。规格分100A、250A、630A，整定值根据用户选择，并生产组合配电、动力插接箱。
插接箱的插脚是重要的部件。本厂独有的工艺在插脚另加二块65猛弹簧钢片，确保插接200次以上仍具有良好的弹性接触。
JACK BOX
There is an automatic air-swith(its model can be choosed by users themselves)in a jack switch box.it can avoid the overload of branch and short curcuit Standards include 100A,250A and 630A ＆#118alue of rectification is choosed by users themselves.We also produce combined jack box of power distribution and power.
The base pin of a jack box is an improtant part.My factorys unique technique is adding two 65 manganese metal piece of spring to the base pin so it can ensure to keep the springing contact still fine after being contacted for more than 200 times.
