Wholesale Surge Arrester, Surge Arrester Manufacturer

In electrical power systems, the surge arrester is vital. It safeguards electrical equipment from overvoltage surges due to lightning, switching operations, etc. When abnormal high voltages hit the grid, it channels excessive energy to the ground, protecting devices like transformers and lines.

During a voltage spike, the arrester kicks in. Its non-linear resistor elements change resistance based on voltage. Under normal voltage, they're high-resistance; during a surge, resistance drops, letting current flow to ground to limit voltage on protected equipment.

Surge Arrester Components:

● Housing:

Made of sturdy, insulating composite materials, it protects internal parts and isolates the arrester electrically.

● Non-linear Resistor Elements:

Core components that adapt resistance to handle voltage changes.

● Arresting Gaps (in some types):

They work with resistor elements during high surges, enhancing protection by creating a conductive path when needed.
