The H2O is form by Covalent bond then why we use electricity to breakdown?

You have to add H2SO4 also for breakdown.
Because water is an insulator. 100% pure water doesn't conduct electricity very well at all. When acid such as sulfuric acid (H2SO4) is added, the compounds separate into separate ions and having that small number of ions increases conductivity astronomically. This doesn't require an acid, you can use a base or almost any compound. Even normal tap water has enough ions to be a good conductor, which is necessary to efficiently perform electrolysis.
Hope this will help you.

This is not my question
I have answered elaborately
I know this
But why we electrolytic other than thermal
so, you tell me which covalent compound break by thermal?
Thanks for help me
In thermolysis, water molecules split into their atomic components hydrogen and oxygen. For example, at 2200 °C about three percent of all H2O are dissociated into various combinations of hydrogen and oxygen atoms, mostly H, H2, O, O2, and OH. Other reaction products like H2O2 or HO2remain minor. At the very high temperature of 3000 °C more than half of the water molecules are decomposed, but at ambient temperatures only one molecule in 100 trillion dissociates by the effect of heat.
The high temperatures and material constraints have limited the applications of this approach.
