Which of the following is NOT a property of good insulating material
used for cables?
Non-inflammable
High dielectric strength
High insulation resistance
High permittivity
High permittivity
Good insulating material has following
properties
●The material should have high
mechanical strength so that it carries the tension and weight of the
conductors.
●They must have high dielectric
strength.
●Material has non-inflammable
properties. ^
●The material is highly resistive for
preventing the flow of leakage current from conductor to earth.
• Low permittivity
