Lightning Protection

Complete Lightning Protection System 

External LPS

Internal LPS

  • Protects the structure from lightning strikes
  • Works outside the building
  • Protects people & equipment from surges
  • Works inside the building

Complete lightning protection = External LPS + Internal LPS

External LPS

Air Termination System

Catches the lightning before it reaches a structure.

Can consist of the following:

  • Air rods / masts
  • Spanned wires
  • Conductors fixed to the roof

Down Conductor System

The function of the DCS is to safely conduct the lightning current from the ATS to the ETS without damaging the building.

Important aspects of DCS:

  • Multiple paths to ground (reduces damage risk)
  • As straight and short as possible — no loops
  • Conductors at each corner and evenly spaced per LPL
  • Connected to building steel and other metal where suitable

Earth Termination System

Lightning is fundamentally different from standard electrical faults—it carries immense, unpredictable energy that can cause severe damage in an instant.

Our LPS system is engineered to recognize and account for these unique challenges. By employing advanced materials and precision engineering, our design delivers safe, controlled dissipation of high-energy lightning impulses deep into the soil.

Internal LPS

Internal lightning protection systems are engineered to prevent lightning currents from entering through power or communication lines, these systems safeguard not only your critical equipment but also the well-being of everyone inside.

Surge Protection Devices

Surge Protective Devices (SPDs) are installed at power and communication entry points to block lightning currents and voltage surges before they reach your equipment.

  • Type 1 devices are installed at the main distribution panel to block major external surges.
  • Type 2 devices are installed at distribution panels to handle residual and internal surges.

A Complete LPS = External + Internal Systems Working Together

We handle everything:

  • Lightning Risk Assessment (SANS 62305-2)
  • System Design (LPL I–IV compliance)
  • Installation & Certification
  • Ongoing maintenance for long-term safety

 

We’ll determine exactly what level of protection your facility needs and build a compliant solution tailored to your structure.
