Max . rated temperature of the cable conductor is 90 電纜導(dǎo)體的最高額定溫度為90 。
Numbering of cable conductors 電纜線芯編號(hào)
A method that can ma ke htsc cable conductor layer - current balanced is pointed out 通過(guò)對(duì)這些結(jié)構(gòu)參數(shù)組合的調(diào)整,提出了使導(dǎo)體各層電流均勻的原則和方法。
Main application range : applicable to lead wires of every kind of electronic parts , such as capacitor and resistor . electrical wire , cable conductor ( single or stranded cable ) ; and every kind of cable shielding material 主要應(yīng)用范圍:適用于各種電子零件之引線,如電容器,電阻器等;電線、電纜導(dǎo)體(單支或絞線) ;以及各種電纜屏蔽編織用材。
Model sywly - 75 physics high to foam polyethylene insulating , aluminum pipe other conductor coaxial cable suitable for catv backbone project , its interior conductor adopt bastion of iron make aluminium , other conductor adopt aluminum pipe , the two have the same hot coefficient of expansion and modulus of elasticity , woods reduce in cable conductor draw the troubles that are led to the fact Sywly - 75型物理高發(fā)泡聚乙烯絕緣、鋁管外導(dǎo)體同軸電纜適用于catv主干線工程,其內(nèi)導(dǎo)體采用銅墻鐵壁包鋁,外導(dǎo)體采用鋁管,兩者具有相同的熱膨脹系數(shù)和彈性模數(shù),林減少了由電纜內(nèi)導(dǎo)體拉拔所造成的故障。
This article makes a numerical simulation and analysis of the skin effect of the downhole heating cable conductor by using the finite element method , thereby finds out the distribution characteristics of the current density of the cable , and indicates the effect of the frequency of alternating current on the skin depth 摘要運(yùn)用有限元法,對(duì)交頻井下伴熱電纜導(dǎo)體內(nèi)部的集膚效應(yīng)現(xiàn)象進(jìn)行了數(shù)值模擬和分析,比較直觀地得出交頻電纜中電流密度的分布特性,以及交流電的不同頻率對(duì)導(dǎo)體集膚深度的影響。
