Design Guide for Electrical Energy Transmission in Underground Cable Network

Voltage level of transmission line network is the key considering design guide factor for bouth overhead transmission system and underground cable transmission system.

Schematic line diagramin below , the specific voltage level guide are used for conventional overhead transmission and new concept underground transmission network system for- Power Generation; Bulk Transmission; Sub-Transmission; & Distribution System.
What The Distribution Voltage Level Is?In electrical power transmission and distribution system, voltage levels are divided into different category considering the equipment operating capability, such as- Low Voltage (LV)              - up to 1000Volt; Medium Voltage (MV)       - 1000 Volt ~ 35 kilo Volt; High Voltage (HV)            - 35kilo Volt ~ 230 kilo Volt; Extra High Voltage (EHV)  - above 230 kilo Volt; & Ultra High Voltage (UHV)  - above 800 kilo Volt. Also, very safe low voltage like less …
