Which of the following is NOT an advantage of oil filled cables over solid cables?

Which of the following is NOT an advantage of oil filled cables over solid cables? Correct Answer Installation and maintenance is straight-forward.

Oil filled cables have the following advantages against solid cables:

  • The oil filled cables have greater operating dielectric stress.
  • Such type of cable has greater working temperature and greater current carrying capacity.
  • Oil filled cable has better impregnation as compared to solid cable.
  • In oil-filled cable, impregnation is possible, even after sheathing.
  • In such type of cable, there is no void formation.
  • The size of oil-filled cable is small as compared to solid filled cables because their dielectric thickness is less.
  • In oil-filled cable, the defect can easily be detected by oil leakage.

 

So, Installation and maintenance is straight-forward is not the advantage of Oil filled cables.

Modern civilization is completely dependent on energy, which has therefore to be abundant and also economical. About 85% of the world's energy is supplied by oil, coal and natural gas while nuclear, hydro, wind and solar power and biomass supply the rest. Coal, nuclear and hydro are used primarily to generate electricity while natural gas is widely used for heating. Biomass is used both for heating and cooking. The wind and solar power is the future's hope as they are sustainable energy sources. Oil powers almost all machines that move and that makes oil uniquely versatile. Oil powered airplanes carry 500 people across the widest oceans at nearly the speed of sound. Oil powered machines produce and transport food. Oil powered machines are ubiquitous. Clearly, we live in the age of oil but it is drawing to a close. According to data available if oil production remains constant until it's gone, there is enough to last 42 years. Oil wells will produce less as they become depleted, which will make it impossible to keep production constant. Similarly natural gas and coal will last another 61 years and 133 years respectively. Naturally, as they become scarce, they become expensive, leading to a worldwide energy crisis. If we are to survive on this planet, we have to make a transition to sustainable energy sources. The transition may be willy-nilly or planned - the choice is ours. The dawning era of limited and expensive energy will be very difficult for everyone on earth but will be even more difficult if it is not anticipated. It is of utmost importance that the public and policymakers understand the global energy crisis and act in tandem to ensure that the species 'homo sapiens' does not become extinct.
