High Quality Lightning Arrester Product
The function of the arrester
The main function of the zinc oxide arrester is to prevent the intrusion of lightning waves or internal overvoltage. Usually, the arrester is connected in parallel with the protected device. When the line is struck by lightning and has overvoltage or internal operating overvoltage, the lightning arrester is discharged to the ground to avoid voltage shock waves and prevent the insulation of the protected equipment from being damaged.

KS11 Series 10KV Mine Oil-Immersed Transformer
This series of products are made of high-quality grain-oriented, high-quality and high-permeability silicon steel sheets stacked. The low-noise and low-loss fuel tank has a sturdy structure. High and low-voltage cable junction boxes are welded on both sides of the tank wall. They are used for cable wiring. The high-voltage coil must have a tap voltage of ±5% of the rated voltage. .The power supply must be cut off first, and then the wind and rain of the tap switch on the box wall must be removed to convert the voltage transformer. The low-voltage side of the voltage transformer allows the “Y” type to be connected to 693V or the “D” type to be connected to 400V for power supply, and the secondary is directly installed in the cable junction box. The end leads out six porcelain sleeves for the user to connect the transformer hoisting and use the hoisting climb welded on the box wall. The bottom of the transformer box is equipped with a skid, and there are installation holes on the skid, which can be used for mines and mine cart rollers when needed.
KS11 series mine transformers are used as power distribution equipment for mine consolidation. The product has the characteristics of small size, easy to merge, reasonable structure, low loss and good thermal performance.
