0.6/1kV PVC
insulated Cable
a). Application:
0.6/1kV
PVC insulated Cable, It to be used for
indoors, in tunnel, in down wells,cable furrow or pipe,
underground.
Note: the single core
armored
cablesare used for
D.C. system only. As for
A.C.system,
armor layer should be used of non-magnetic material or magnetic
isolation measures.

Installation:
1. The installation temperature
should not over *0℃, If the ambient temperature is lower than 0℃,
the cable should be preheated.
2. The bending radius of cable should not less than 8 times.
3. After installantion, the cable should with stand voltage test
for *5min. 3.5kv D.C.
In air:
1. As the single core cable
laying in parallel, the distance between the cable’s center is 2
times (for cables which cross section area of conductor ≤**5mm2)
and
*0mm (for cables which cross sectional area of
conductor≥**0mm2)
2. Ambient temperature: *0℃
3. Max. temperature of conductor: *0℃

Direct in ground:
1. When the single core cables are installed separately, the
distance between the cable’s center is 2 times of the cable
diameter.
2. Ambient temperature: *5℃.
3. Max. temperature of conductor: *0℃.
4. Soil thermour resistivity: 1.0℃. m/w.
5. Depth: 0.7m
