House wiring usually comprises copper conductors which are
insulated with PVC (see Figure 4.5).
Polychloroprene (PCP) is used to insulate copper conductors in
farming installations where resistance to ammonia and other such
corrosives is required.
The insulating material in mineral-insulated cables is magnesium
carbonate which spaces solid copper conductors within a copper
It has a number of advantages amongst which is the ability to
operate at red heat - a property which no other
