在电力系统中,导体电阻的数据大小决定了其传输性能的品质与安全裕度,而电阻的大小与导体的材料(不同材料有不同的电阻率ρ)、截面积、长度及温度(一般温度越低电阻越小除特殊材料外)有关。如何判断电阻的合格性并不是依据电线外径的大小而是通过专业检测机构的检测来判定的。1事故简述2016年5月28日,青岛某项目,客户因在验收电线BV2.5、BV4等相关规格,依据GB 50411—2007《建筑节
In the power system, the size of the conductor resistance determines the quality and safety margin of the transmission performance, and the size of the resistance depends on the material of the conductor (different materials have different resistivity ρ), cross-sectional area, length and temperature The lower the resistance of the smaller except for special materials). How to determine the resistance of the resistance is not based on the size of the wire diameter but through the detection of professional testing agencies to determine. An accident briefing May 28, 2016, a project in Qingdao, customers in the acceptance of BV2.5 BV4 wire and other related specifications, according to GB 50411-2007 "Building Festival
