steel tape armoured power cables

steel tape amoured power cableis for laying indoor, in tunnels or direct burying in earth able to bear external mechanical forces. Power-cable lay notice: 1.When cable installation parallel with heating pipes, the distance between the should keep 2m; When cross,should keep 0.5m 2.When cable installation in parallel or cross iwht other pipes, the distance between them should keep 0.5m 3. When cable lay directly in the ground, the depteh of 1 35kv cable should not less than 0.7m 4. When cable is installed(10kv or less) in parallel, the distance between them should be not less than 0.1m, 10 35kv should not be less than 0.25m; when cross should not be cess than 0.5m 5. the temperature of cable installation should bot less than 0, the bend radius; Multi>=core=15(D+d), single-core cable >=20(D+d)[D:Dis outer diameter of the cable, d:dis the outer diameter of the conductor]
