What is difference between PVC cable & XLPE cable?
Answer Posted / malay kumar dutta
PVC cable does not mean anything.Conductor insulation can
be made of PVC or XLPE depending on selection by designer.
Outer sheath and innersheath is made of PVC or Polyethylene
in both the cases.
PVC is Polyvinyl Chloride and XLPE is cross linked Poly
ethylene which is more chemically stable
XLPE cable can be used for Low, medium and high voltage
applications. Conductor is insulated with XLPE which can
withstand higher conductor temperature during normal and
short circuit condition. It has better insulation value,
lighter in weight and better current capacity with lesser
bending radius.
Depending on application, it is selected and in areas which
is having moisture XLPE cables are preferred. It has lesser
chance of mechanical damage and can be used for underground
application with armouring and MDPE outersheathing.
