silicon has 4 valence electrons leaving a half empty shell sharing electrons covalently with its neighbors leaving no free electrons, copper has 1 valence electron which is so loosely bound it forms an electron gas which conducts easily. silicon can be doped with tiny amounts of impurities having 5 or 3 valence electrons, providing free electron or missing electrons called holes to carry current.

Why using semiconductor protection for HT cable?
In a HT cable there are 2 layers of semiconductor one on the conductor and second on the XLPE insulation. As we know semiconductor behaves as conductor when temperature rises. So when the HT cable is on load its conductor temperature rises due to this the semicon layer which is on conductor behaves like conductor and as a result overall cross section area is increased. now the second semicon layer which is over XLPE on temp rise behaves as conductor and used for dessipating heat out of conductor as the cable heat due to load.
What are the three categories of materials used in electronics?

It is a semiconductor
Can a semiconductor be made to become a conductor or an insulator?
Yes, a semiconductor can be made to behave as a conductor or an insulator by controlling the amount of impurities added to it. Adding impurities through a process called doping can change the conductivity of the semiconductor material, making it act like a conductor or an insulator.
