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.
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.
we can answer this question by using the following table. previous level +ve previous level -ve Next bits Next Level Next level 00 +1 -1 01 +3 -3 10 -1 +1 11 -3 +3
12 is ideal. Should no be smaller than 11 nor larger than 14
ht cable that means voltage level is high , it is obvious that power is going to remain same ,so if voltage rises ,current has to be lowered .since current level is less in ht cable therefore size (dia) is less compared to l.t cable , (p=v.i),lt cable current rating is more and voltage rating is less
for 11 kv non effectively neutral earthed system what is basic Insulation level required?
65 meg ohm if it is 11 kv
For earthed and un earthed XLPE cables, the IS 7098 part2 1985 does not give any difference in specification. The insulation level for cable for unearthed system has to be more. In simple statement the manufacturers states that 11 KV earthed cable is suitable for use in 6.6 KV unearthed system.The process of manufacture of cable is same. The size of cable will depend on current rating and voltage level.
Charter basic cable package come with just the basic channels. Depending on the location it is usually less than fifty channels.
A pH=11 is a pH of a basic solution; for example a solution of sodium hydroxide in water.
The pH level of Ammonia is 11.1 which means it's basic (or just 11 if you prefer). The pH of water is 7 (neutral).
To test an a.c. underground cable's insulation, that insulation needs to be tested at a voltage higher than its rated voltage, continuously (a.c. varies, so is unsuitable), for a specified period of time, and with the resulting current being monitored throughout the test. The test voltage/duration applied will be laid down according to the standards of the authority responsible for the electricity distribution system (derived from the cable manufacturers). Typically, an 11-kV underground cable is tested a 17 kV (d.c.) between lines, and at 10 kV (d.c.) line to earth. The duration of the test is typically 5 min. Initially, the current will include the cable's charging current (the cable behaves as a capacitor), but then settles down to the leakage current -typically about 0.2 mA (if attached equipment is not taken into account).

It's the coax cable used for Thick Ethernet.

Yes. RG-11 is 75 ohm cable much the same as any other cable like RG-59, RG-6 or RG-56.
