We delivers protection with precision, regional reach
and technical excellence.
Lightning Protection System
System 2000 is nVent ERICO’s trusted solution for conventional lightning protection, engineered to deliver safe and effective shielding of structures from direct lightning strikes. Designed strictly in accordance with IS/IEC 62305 and other global standards, System 2000 uses air terminals, conductors, clamps, and bonding components that work in harmony to form a fully compliant protection system.
We provide a complete turnkey solution – from detailed risk assessment and system layout to supply and supervision – ensuring reliable protection tailored to your structure.
Design Methodology
nVent ERICO’s System 2000 designs are governed by internationally accepted engineering methods, as outlined in IS/IEC 62305-3. Depending on the structure’s geometry, location, and protection level, one or more of the following methodologies are adopted. There are three positioning methods as prescribes by IS/IEC 622305. They are,
- Protection Angle Method
- Rolling Sphere Method and
- Mesh Method.
Protection Angle Method
The structure is considered to be protected if it is fully situated within the volume protected by the air-termination system. The volume protected by a vertical air termination rod will be in the shape of a right circular cone and hence it is also called as Cone of Protection method. The semi-apex angle will be α and it depends on the class of LPS and the height of air-termination system from the reference plane.
If a structure to be protected cannot be covered using a single air -terminal we have to go for multiple terminals placed as per the coverage distance and all the terminals should be inter connected to form a network. The placement of air terminal using PAM is shown below.
Rolling Sphere Method:
The positioning of air termination system using rolling sphere method is adequate if no point of the structure to be protected comes into contact with a sphere of radius r (depending on class of protection), rolling around and on top of the structure in all possible directions. In this way, the sphere only touches the air termination system.
The radius of the rolling sphere for different classes of LPS is as follows,
The sphere of radius r, is rolled around and over all the structure until it meets the ground plane or object in contact with the ground plane which is capable of acting as a conductor of lightning. A striking point could occur where the rolling sphere touches the structure and at such points protection by an air-termination conductor is required.
Mesh Method:
In mesh method, the building/structure shall be protected by installing conductors in the form of mesh and the mesh size depends on the level of protection.
The following conditions should be fulfilled for protecting a structure by using Mesh Method.
An Example of mesh protection system for flat roof structure is as follows
1) Air termination conductors are positioned on
– Roof edge lines,
– Roof overhangs,
– Roof ridge lines having slope < 1/10.
2) The mesh dimensions should not be greater than the values specified by IS/IEC 62305 part 3.
3) The lightning current should have at least two distinct metal routes to earth termination.
4) Any structures protruding from the surface outside the volume won’t be protected by this method.
5) The route should be the shortest and most direct route.
If the structure to be protected has different roof levels, we have to install mesh of suitable size on all the roof levels and the mesh of different roofs should be interconnected. Any structures protruding from the terrace shall not be protected by the mesh conductors provided.
Product Outline:
System 2000 includes a range of rigorously tested components for effective lightning interception and grounding.
- Copper-Bonded Air Terminals – Rugged, corrosion-resistant vertical rods that provide primary strike capture.
- Conventional Air Terminal Bases – Secure mounting hardware for rooftops, walls, and elevated points.
- Copper-Bonded Conductors – High tensile strength, UL-listed cables for safe current dissipation.
- Interconnecting Clamps – Precision-engineered mechanical connectors ensuring equipotential bonding.
- Test Joints and Grounding Terminals – Access points for routine inspection and system continuity verification.
All components are compatible with nVent ERICO’s CADWELD exothermic welding system for permanent, corrosion-proof bonding.
Certifications and Standards Compliance
System 2000 components and design methodologies meet the following global benchmarks:
- IS/IEC 62305 – Protection against lightning (Parts 1 to 4)
- UL 96 and UL 467 – Lightning protection components and grounding
