      CFW excel in seal busbar specialize in and exchange three-phase four line, three-phase line system, 50-60Hz of frequency, specified voltage to 660V, specified job electric current 200-4000A support distribution system to transmit the
use of electric energy.
CFW铜质母线结构特点 Structure Characteristic
● 母线槽外壳采用辊压型材组装,导电排采用经济电流密度,使其能承受较强的电动应力和热应力,根据表(1)的数据通过动热稳定试验,且试验后母线呈无可觉察的永久变形。
● Busbar trunking out cover adopt roller person who pigeon hole material assemble electric conduction arrange adopt
economic electric current density Enable it and bear strong electric stress and hot stress, alluding to data of from (1) through move hot to test steadily and busbar present and have a aware one of shape for every very after testing.


母线槽导电排包覆多层绝缘材料,能承受3750V的工频耐压,历时1min击穿和闪络现象。
● 在周围空气温度为20±5℃,相对湿度为50-70%的常态下其每节绝缘电阻不低于20MW。
● 母线槽在长期通过额定电流时,其导电部位的温升不超过表(2)所列数值。
● Busbar trunking electric conduction arrange parcel multilevel insulating can bear 3750V engineering of bear pressing frequently, last 1 min have and puncture and flash phenomenon of hold in place with a net.
● Temperature 20±5℃in ambient air, relative humidity each insulating resistance are hot lower than 20MW under 50-70% of the normality.
● Busbar trunking at the time of passing the specified electric current for long time, its electric conduction zh zh of position exceed form (2) listed number valve.


● 母线槽采用高强全封闭结构,防护等级可达IP40。
● 母线槽插接箱与母线槽的插拔次数不少于200次。
● 母线槽在长期通过额定电流时,其导电部位的温升不超过表(2)所列数值。
● Busbar trunking adopt and excel in to tally closed structure defend a grade can reach IP40.
● Busbar trunking insert connect case and busbar trunking insert and set aside number of times no less than 200.
