🔹 Lightning Arrester Base (Gun Metal / Brass)
The base of a conventional lightning arrester is the foundation fitting used to hold the lightning rod securely in position and connect it to the down conductor.
✅ Material Options:
Gun Metal (Bronze Alloy)
Composition: Copper + Tin + Zinc
High strength & durability
Excellent corrosion resistance
Withstands outdoor/harsh environments
Heavy-duty, long life
Brass (Copper + Zinc Alloy)
Good conductivity
Corrosion resistant (but less than gun metal in marine/industrial environments)
Cost-effective compared to gun metal
Suitable for standard installations
🔹 Functions:
Provides a mechanical base for the lightning rod/air terminal.
Ensures firm fixation on rooftops, towers, or structures.
Offers electrical continuity with the copper/aluminium down conductor.
Designed to handle high fault current safely during lightning discharge.
🔹 Typical Specifications:
Material: Gun Metal (preferred for heavy-duty) or Brass (for general use)
Rod Holder Size: 12 mm / 16 mm / 25 mm (customizable as per air terminal size)
Finish: Natural polish or corrosion-resistant coating
Fixing Method: With screws, clamps, or base plate
