Product Description:
OMRDON Spherical Optimized Lightning Rods (also known as flash arresters) is an efficient lightning protection device based on electric field optimization and ionization lightning technology. Through the special spherical structure at the top, it actively enhances the local electric field during the formation of thunderclouds, guides the lightning current to be safely discharged into the ground through the low impedance channel, and provides reliable protection for all kinds of buildings, facilities and personnel. This product is suitable for lightning protection projects of new construction and renovation projects, especially suitable for high-rise buildings, historically protected buildings, communication base stations, chemical parks and other places with high requirements for lightning protection.
Functional Features::
- Highly efficient lightning attraction with a wide range of protectionSpherical design significantly improves flashover efficiency and extends the radius of lightning protection.
- Active Ionization Trigger: Utilizes the electric field principle to actively induce a discharge with fast response time and high reliability.
- Maintenance-free and long-lasting operation: No mechanical parts, all stainless steel structure, suitable for places where frequent maintenance is difficult.
- Strong environmental adaptability: 304/304L stainless steel, corrosion-resistant, suitable for coastal, chemical and industrial polluted areas.
- Fully compliant with national standards: Strictly follow the Code for Lightning Protection Design of Buildings (GB50057-2010) and other domestic lightning protection standards.
- Flexible customization: Supports personalized customization of height, structure, painting, etc. to meet diversified project needs.

Explanation of lightning protection range calculation::
calculation method
Adoption of internationally recognizedRolling Sphere Method (RSM) Carry out calculations, in line with the GB50057-2010 specification requirements. The specific calculation formula is as follows:
When the height of the lightning rod h≤hRhour::
r0=√h(2hR-h)
rx=√h(2hR-h)-√hx(2hR-hx)
Parameter definition table:
- r0: Protective radius of lightning rod at ground level (meters)
- rx: in height hxRadius of protection at the site (meters)
- h: Lightning rod installation height (meters)
- hx: Height of protected object (meters)
- hR: Rolling radius (25m for category 1 buildings, 45m for category 2, 60m for category 3)
Design Recommendations
It is recommended that the protection range simulation and design be carried out by a professional lightning protection engineer.

Installation and Maintenance Guide
Pre-installation
- Confirmation of lightning protection category and completion of engineering design.
- Pre-cast concrete base with pre-built ground bolts or chemical anchors.
- The grounding system shall be constructed and completed first, with a satisfactory grounding resistance test.
Installation steps
- Align the lightning rod flange with the base and tighten the bolts.
- Weld flange to base (if required by design).
- Connecting lead wires to the building's lightning protection network or to a separate lead wire system.
- Anti-corrosion treatment (anti-rust paint or hot-dip galvanizing) for all welded joints.
- Fully check mechanical strength and electrical connectivity after installation.
Grounding requirements
- General building grounding resistance ≤ 10Ω
- Important facilities (such as communications, chemical industry) grounding resistance ≤ 4Ω
- The grounding body is recommended to be made of copper-clad steel or hot-dip galvanized flat steel, buried depth ≥ 0.8m.
Contents of annual inspections
- Check the connection points for firmness and corrosion.
- Measurement of grounding resistance for compliance
- Check lead wires for integrity and insulation protection breaks
- Record and file inspection results
