Wire with a single core copper wire is good, or multi-core good?
First, this should be based on specific circumstances, single-core and multi-core is the main difference between the different softness of the wire. In fact the two do not exist which good question, but the use of the environment is not the same. Second, the family decoration: . the lighting line, can be used 1.5 single strand copper wire. More than . 2P (including) more than air conditioning, that is, hot water heater, Yuba must use 4 square double strand copper wire; . the wall buried the best choice for single wire copper wire, according to the need to choose 4 square Mm, 2.5 square millimeters, 1.5 square millimeters and other specifications.
In the air defense regulations, the pipelines of the air defense zone need to be treated with the protective wing ring. The bridge frame is designed according to the cable laid in the bridge. The cable size and quantity determine the size and quantity of the casing. Increase the standby, air defense requirements casing with hot galvanized treatment, both sides of the exposed wall shall not be less than 100 mm, wing ring production can refer to rigid waterproof casing or flexible waterproof casing (explosion-proof). The general construction plans will have a clear sign, or should be presented to the Design Institute in the trial.
Second, the laying of the bracket, the power cable should be placed in the upper control cable, but 1000 volts below the power cable and control cable can be laid side by side
(4 × 185 + 1 × 95) is the cable specifications, indicating that the cable has 5 cores, of which 4 cores are 185 Square millimeters, one core is 95 square millimeters. General 185 line is the main core, power with, 95 for the ground core, ground use.
