Explanation
Underground cables are buried deep primarily to minimize the shocks and vibrations from traffic and other surface activities. While reducing temperature stress and preventing exposure from soil removal are important, the main reason is to protect cables from mechanical disturbances caused by vehicles and similar factors.
