Explanation: The depth of cable trench for laying cables depends on various factors, including the voltage rating of the cables. For 1.1 kV cables, the recommended minimum depth of the cable trench is typically around 0.75 meters. This depth helps to provide proper insulation and protection for the cables, preventing damage from external factors and ensuring the safety and reliability of the electrical system.
It’s important to follow local electrical codes and regulations, as they may specify specific requirements for cable trench depths based on voltage ratings and other considerations. Always consult the relevant standards and guidelines to ensure that the cable installation meets safety and performance standards.
