Consider  a conductor with the cavity with no charges places in side the cavity . 
Whatever the size and shape of the cavity and what ever be the charge on the conduction  and the external fields in which it might be placed . 
The electric field inside the cavity is zero. 
(ie) the cavity inside inside the conductor remains shielded from outside electric influence. 
This is known as electric shielding . 
Applications : 
(i)In thunder strong accompany by lightening it is safest to sit inside a car , rather than near a tree or open ground.  
The metallic body of the car becomes an electrostatic shielding from lightening .  
(ii)Sensitive components of electronic devices protected or shielded from external electric disturbances by placing metal sheets around them . 
(iii) In a coaxial cable the outer conductor connected to ground provides an electrical shield to the signals carried by the central conductor .   

Answer 2

Electrostatics shielding is the phenomena that is observed when a Faraday's cage operates to block the effects on and external field on its internal content are the effects of an internal field on the outside environment.
(1) electrostatic shielding is the processor of covering material so as to make the effects feel zero inside it....
