What are the general items of a construction project
The intrinsically safe signal control cable is suitable for various intrinsically safe circuits such as the remote control circuit and the protection circuit of the automatic control system with explosive environment. It has the advantages of small distributed parameters, external disturbance and inter-line crosstalk. The main models are: intrinsically safe PE insulation, PVC sheathed 2-core stranded shielded control cable; intrinsically safe PE insulation, PVC sheathed 2-core twisted shield with cable; intrinsically safe PE insulation, poly PVC sheathed 3 core stranded shielded control cable; intrinsically safe PE insulation, PVC sheathed 3 core twisted shield with cable. 1. Rated voltage of 450 / 750V.2. Separate laying or effective isolation from non-intrinsically safe cables. 3. The operating temperature of the cable is -20 to 65 degrees. 4. Fixed laying indoors. Cable trench or pipe.
In the laying of the time when there is no specific requirements if not and some cable to go the same bridge more
