Note: 1.The reference current carrying capacity is determined according to the parallel placement of three cores (the adjacent spacing is equal to the outer diameter of the cable),and the current carrying capacity correction coefficient is shown in the following table.The outer diameter,weight,insulation resistance and current carrying capacity of the above cables are for reference only,and only conventional non flame retardant and non fire resistant parameters are provided.If there are parameter requirements for flame retardant and fire resistant cables,please contact our company to provide them. 2.Conductor sizes of 6 mm²and below are class 1 conductors.For cable parameters of class 2 conductors,please contact our company.

Note:If you need other types of cable structure parameters, please contact our company.
