Feature:
The zinc oxide surge arrester is the most advanced over-voltage protector in the world. Due to make the resistor disc of core component mainly adopt zinc oxide arrester. Compared with the conventional siliconcarbide arrester, this prescription of the product improves greatly the volt-ampere characteristics of the resistor disc and increase through- current capability at over-voltage so as to bring a rad local-changes for the characteristics of the arresters. |
#4. Multiple-Gap Arrester:
Multiple-Gap Arrester
Arresters of this type are designed to be small metal cylinders in series. Which are separated from each other by means of air and are insulated from each other.
Whose first cylinder is connected to the line and the last and its next cylinder in series connected to the earthing. The intermediate cylinder has a shunt barrier at some intervals. The distance between the cylinders depends on the voltage of the line.
#5. Electrolytic Arrester:
Arresters of this type have a large discharge capacity only. It works in such a way that a thin strip of aluminum hydroxide is deposited on the electrolyte completely immersed on the aluminum plates. The plate acts as high resistance to low cost but fixed value. Less resistance to voltages than. Puncture at a voltage of more than 400 volts and causes the free flow of current to the earth.
When the voltage remains at its normal value of 440 volts, the arrester again provides high resistance in the path and stops the leakage.
Advantages of Lightning Arrester:
The benefits of Lightning Arrester are as follows:
Damage caused by lightning can be minimized.
Easy to use.
Provides protection of equipment outside the substation.
Damage to the overhead line can be avoided.
Outlet surgeries can be avoided.
Electromagnetic interference.
Disadvantages of Lightning Arrester:
The Disadvantages of Lightning Arrester are as follows:
Prevents excessive space in the line.
Installation costs are higher.
Q: Can we get a sample for reference?
A: Yes, as long as the goods are conventional type, and you will be
charged sample cost plus related shipping cost. Once you place an
order to us, we can return or deduct the sample cost to you.
Q: How to solve the quality problems after sales?
A: Take photos of the quality problems and send to us for our
checking and confirming, we will make a satisfied solution for you
within 3 days.
Q: What is the lead time?
A: The lead time depends on the quantities ordered, generally
within 25-35days upon the receipt of advance payment.
