The insulating material for a cable
should have
High dielectric strength
High mechanical strength
Low cost
All of the above
Low cost
he insulating materials used in cables
should have the following properties.
• High insulation resistance-To avoid
leakage current.
• High di-electric strength-To avoid
electrical breakdown of the cable.
• High mechanical strength-To withstand
the mechanical handling of the cable.
Low cost-So as make the under ground
available proportion.
