Analysis of Lighting Cable Selection for Road Engineering
The lighting of community roads has the characteristics of long distribution lines and widely distributed lamps.When selecting ca-bles,it is necessary to carefully consider conductor material,insulation level,and number of cores.At the same time,the selection of the ca-ble cross-section is also crucial.This not only needs to be based on multiple factors such as protective coordination installation method,and environmental correction,but also requires precise calculation of the voltage drop and short circuit current of the distribution line.In addition,in order to ensure stable operation of the system,it is necessary to strictly verify the sensitivity of the short circuit protection and overload pro-tection of the distribution line.For this purpose,we specially drawn up a coordination table for the maximum protection length of B-type and C-type miniature circuit breakers with different cross-sectional copper conductors,aiming to provide with comprehensive and accurate refer-ence basis.
