66kV Surge Arrester

When the communication cable or equipment is operating under normal operating voltage, the 66kV surge arrester will not have an effect, and it is regarded as an open circuit for the ground. Once a high voltage occurs, and the insulation of the protected equipment is endangered, the arrester immediately acts to direct the high-voltage inrush current to the ground, thereby limiting the voltage amplitude and protecting the communication cable and equipment insulation. When the overvoltage disappears, the 66 kv lightning arrester quickly returns to its original state and makes the communication line work normally.

What is the lightning arrester rating for 66kV?

The lightning arrester rating for 66kV systems is essential to ensure effective protection against lightning-induced surges. At YF POWER, we offer a range of 66kV surge arresters specifically designed for this voltage level. Our 66kV lightning arresters are built to withstand high voltage surges and divert excessive electrical energy to the ground, safeguarding your equipment and ensuring the smooth operation of your electrical system.
