2 .Application
For laying indoors,in tunnels and in ducts,unable to bear external mechanical force.
3.Operation Characteristic
The Maximum operating temperature of the cable for long period use shall not exceed 70℃, the circuit temperature for 5 seconds not exceed 160℃. The cable is not limited by the difference of level when installed and the ambient temperature shall not be below 0℃.The minimum bending radius for single core cable is 40(D+d)mm, for multi core cable is 30(D+d)mm,(D and d are nominal outerdiameter of main conductor of cable respectively if the main Conductor is not round D = 1.13 . S is the moninal cross sectional area of the main conductor ductor in mm). The single core armoured cables are only suitable for D.C.lines.
4.Conditions of Use:
VV22 cables are suitable for direct burial underground, and can be laid indoors, in cable trenches, tunnels and pipelines. The cables can withstand certain mechanical external forces, but cannot withstand large tensile forces.
Number of cores: one core (single core), two cores (dual core), three cores, four cores (including "3+1" and fourth cores), five cores (including "4+1", "3+ 2” and fifth core).
