How do you design an 11kv underground cable?
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.
Draw the analog signal for 2B1Q scheme for binary representation of 0011001100110011?
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
What is the size of font for resume?
12 is ideal. Should no be smaller than 11 nor larger than 14
What is the difference between HT and LT line?
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
What is Dielectrical Insulation withstand level?
The dielectric insulation withstand level refers to the maximum voltage that an insulating material can handle without breaking down. It is a measure of the material's ability to resist electrical breakdown and maintain its insulating properties under high voltage conditions.
What should be minimum insulation resistance value for 11 kV HT cable?
65 meg ohm if it is 11 kv
Difference between earthed and unearthed cable?
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.
How many channels on basic cable?
Charter basic cable package come with just the basic channels. Depending on the location it is usually less than fifty channels.
What is the Ph level for a strong basic solution?
How many strong?. Always, upon 7, a solution is pH basic, 14, is realy strong basic.
Is pH11 an acid?
No, pH 11 is not an acid. In fact, it is a basic pH level, indicating a solution is alkaline or basic. Substances with a pH higher than 7 are considered basic, while those with a pH lower than 7 are acidic.
What has a pH level of 11?
A pH level of 11 indicates a substance is alkaline or basic. Common examples of substances with a pH of 11 include household ammonia, bleach, and some soaps. It is important to handle and use these substances carefully due to their potential corrosive nature.
What is the pH level of ammonia NH3?
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).
What is the ammonium hydroxide pH level?
The pH level of ammonium hydroxide is typically around 11-12, making it basic or alkaline.
Why dc supply is used for testing the 11 kv cable?
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).
What is pinesol on the pH scale?
Pine-Sol has a pH level ranging from 10 to 11, making it alkaline. This indicates that it is a basic solution.
What is rg-11 cable?
It's the coax cable used for Thick Ethernet.
