| 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. |
#6. Expulsion Type Lightning Arrester:
Arresters of this type have an improvement in the distance of the rod in which it shuts off the frequency of power. This air raster uses a tube made of fiber which is very effective, separating the spark gap and the interrupted spark gap inside the fiber tube.
Expulsion Type Lightning Arrester
The spark of impulse inside the fibrous tube during operation destabilizes some of the fibrous material of the arc tube in the form of gas, which is called a vent from the bottom of the tube. Thus, extinguishing the arc is just like circuit breakers.
#7. Auto valve Arrester:
This type of arrester consists of several flat discs of mesh material that are mounted on top of one and separated by thin mica rings. Disk content is not homogeneous and admin content has also been added. So the glow discharge occurs in the capillaries of the material and the voltage drops to about 350 volts per unit. The disk is configured in such a way that normal voltage does not cause discharge.
#8. Valve Type Lightning Arresters:
This type of arrester applies to electrical systems that are more powerful. These devices consist of two main parts, the sequence of spark gaps as well as the series of non-linear resistor disks. These devices can operate whenever a high voltage spark strikes the gusset and the non-linear resistors have a grounding voltage. Whenever the surplus power surge stops, the spark gaps can be pushed apart by the resistors.
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.
Q: What is your terms of payment ?
A: We accept West Union, T/T, irrevocable L/C at sight. Prefer T/T 30% deposit before production, the balance against copy of B/L.
Q: Can you print our brand on the product?
A: Yes, of course, we also do OEM to print client’s brand on the product.
