Why semicon layer needed in high voltage power cable manufacturing process?
to avoid electrical field strength which may give rise to partial discharge and ageing of power cables
What is the difference between sheathed and non-sheathed cable?
Cable sheath current is a current induced in the sheath by radio, magnetic or other interference, or a fault condition. The cable sheath should be grounded at one end so that this current flows to ground safely.
What is the current amp of 150sqmm aluminum cable?
445 amps. For example Mulberry AAAC cable.
Why armour HT XLPE power cable required to Earth?
because when ever fault current occurs then the cable wont get damaged due to cable armored earthing to the gland for fault current to pass through groung
How do you selecte cable for load?
if your load draws a max of 15 amps then you would use 14-16 gauge wire. the lower the gauge the more current that is allowed to pass. there are charts that show max current for diameter of wire
What dangers of partial discharge of cable?
it is very important question
Why semicon layer needed in high voltage power cable manufacturing process?
to avoid electrical field strength which may give rise to partial discharge and ageing of power cables
Why Cable gets heated when current flows more than its rated current why?
Because if the rated current is lower than the actual current, it causes resistance to the electrical flow which in turn is dispelled as heat.
What is current capacity of 95 sqmm cable?
what is current capacity of 95 sqmm cable?
What are the causes of derating of cables?
1. We consider cable de-rating factor, because the method of laying of cable either in air, duct or trench, affect the current carrying capacity as dissipation of heat in air is more than in duct or trench. Now the factors that causes derating are 1. ambient temperature (this is the average temperature of the plant). If surrounding temperature is higher than cable temperature at which it is designed then that increase the resistance of cable conductor which decreases the current 2. Number of cables in cable tray either they are touching each other or at a distance. If cables are touching each other, they created dielectric field around them which in case of touching causes interference with one another that causes resistance to increase. 3. No. of cable trays in a tier.
What was the cause and effect of cable television?
There are many causes and effects of cable television. These causes and effects of cable television include entertainment and laziness.
What do you do to reduce the strain placed on the strands of a cable during swagging?
Bend the cable to a 45 degree angle after partial insertion into the terminal
What is the difference between sheathed and non-sheathed cable?
Cable sheath current is a current induced in the sheath by radio, magnetic or other interference, or a fault condition. The cable sheath should be grounded at one end so that this current flows to ground safely.
How do you determine what is drawing the battery down after you already changed the battery and alternator?
Disconnect the negative cable and connect (insert) an ammeter between the battery and the battery cable. Remove the fuses one by one and see which causes the current draw to drop.
What is the cable size for 1 to 100 Amp current list?
25mm cable
What is the cable size of 1600kVA transformer?
Cable size is determined by current. You did not provide the current, nor did you include the voltage so that we could calculate the current. Please restate the question, and include either the current or the voltage.
Why would the battery keep draining?
Check earth connection. Sometimes if wires aren't connected right, running the car will discharge the battery instead of charging it... ----------------------------------------- Check for a current draw by disconnecting the negative cable at the battery and hook a test light between the cable and the battery. Remove fuses until the light goes out. While doing so remember to depress the door jam switch as it will show a current draw.
