It is not necessary to design an 11 kv underground cable. There are several 11 kv underground cables already on the market. You can choose exactly which cable will fit best for your project and purchase it.

Why earth cable used along with the 11kV power cable?
If you are referring to an 11-kV underground cable, these are normally armoured and, in the case of older cables, have a lead sheath to prevent moisture ingress into the cable. The lead sheath and metal armour are earthed to ensure that, in the event of mechanical damage to the cable, there is a low-resistance path back to the source to sufficient earth-fault current flows in order to operate the circuit's protective system. Overhead lines do not normally have a separate earth conductor.
What is the maximum capacity of 11kv transformer?
It depends on the design of the transformer but 1 MVA is a common size for an 11 kV / 415 v three-phase transformer.
What is the minimum value of Ir test in 11kv cables?
4444
Why the generating stations produce 11kv voltage and it step up to 33kv during transmission.. why we should not use 230volts to generated and can step up to 11kv.. why?
if we take 11kv /33kv yhe current produced will be less when compared to 230v/11kv.. the curent produced will be gerater than 1000amp or above so the winding of the transformers will damage because thier is no winding at present to with stand the huge amount of current by K.B.N.GANGADHAR sasi institute of technology and engineering
What is the base mva of 33Kv?
750MVA to 1000MVA for 33kV and 350MVA for 11kV
What is underground feeder cable?
It is a cable that feeds.

What type of armour cable to you need to run underground to your garage?
Armoured cable is not rated for underground installations. You have to use a cable with a designation for direct burial or wet and damp locations.
What should be the distance between underground power cable and telephone cable?
300mm
What is the maximum capacity of 11kv transformer?
It depends on the design of the transformer but 1 MVA is a common size for an 11 kV / 415 v three-phase transformer.
How much must be the distance between two conductors of 11kv line?
600mm is the distance between two conductors in 11kv line
How do you design oil 11kv circuit breaker?
You don't need to. They've been around for decades and are probably as well-designed as they're ever going to be. Now, if you're asking 'What are the design features of an 11-kV OCB?' then that's another story...
How do cable companies get their TV signal?
Cable companies utilize satellite technology to initially get the signal, then it is distributed via underground or above ground cable.
How do you locate underground cable fault?
Time Domain Reflectometers can be used to locate where an underground cable fault lies. Time Domain Reflectometry (See wikipedia) is a measurement technique to identify the location using reflected signals sent down the cable line.
What is the cable size that are used in 11kv system?
It depends on the power rating of the circuit but a common size would be 95 sq. mm up to about twice that. 11 kV systems are usually 3-phase 3-wire. Underground cables use copper while overhead ones tend to use uninsulated aluminium or aluminium conductor steel reinforced (ACSR) cables.
Why was the Cable Television Needed?
one of the most important facts about underground cables is that repairs due to weather conditions such as hurracanes or tornadoes was not required since underground, this cable is protected against those dissasters.
