FAQ
The cable standard is IEC 60840 (can also be customized as needed), the conductor standard is IEC 60228.
Yes, because the cables are designed and manufactured to meet the applications of primary underground distribution suitable for use in wet or dry location, direct burial, underground duct, and exposed to sunlight.
Conductor – Plain annealed class 2 circular compacted conductor or segment copper conductor or Aluminum Class 2 Conductor
Binder tape – Semi-conductive Tetoron tape
Conductor screen – Semi-conductive compound
Insulation – Cross linked polyethylene (XLPE)
Insulation screen – Semi-conductive compound
Watertight Bedding – Semi-conducting water swellable tape
Metal screen – Copper wire
Metal sheath(screen) – Weld corrugated aluminum sheath coated asphalt
Watertight Bedding – Semi-conducting water swellable tape
Radial direction watertight layer – Aluminum plastic composite tape
Outer sheath – High density polyethylene (HDPE) coated graphite
– Polyvinyl chloride compound (PVC) coated graphite
There are 36/66kV,64/110kV,76/132kV,87/150kV&127/220kV.We can do the voltage up to 500kV.
Why does this matter?
Even though system voltage and Um are the same, cables are not interchangeable. Earthing and fault duration dictate insulation requirements.
What are the consequences of incorrect selection?
Insulation failure, reduced cable life, partial discharge damage, catastrophic failure during faults.
