Lightning protection and surge protection
Malaysia has some of the highest lightning activity in the world. We install penangkal petir systems — air terminals, down conductors, earthing and surge protection — and work with a specialist partner for the formal lightning risk assessment.
Scope of work
Protecting the structure and the equipment inside it
External protection
Perlindungan luar
- Air terminals, roof conductors and down conductors installed on roofs, parapets and structures.
- Bonding of metal roofing, gutters, railings and services entering the building.
- Earth termination network with earth pits and ring earth where required.
- Test joints and inspection points so the system can be verified later.
Internal protection
Perlindungan dalam
- Surge protective devices (SPD) at the main switchboard and sub-boards.
- SPD for data, telephone, CCTV and signal lines where equipment is exposed.
- Equipotential bonding to limit dangerous voltage differences inside the building.
- Protection for inverters, EV chargers, lifts and sensitive electronics.
Inspection and upgrade
Pemeriksaan & naik taraf
- Condition inspection of existing lightning protection after strikes, extension or renovation.
- Earth resistance testing and continuity checks across the system.
- Repair or replacement of corroded conductors, broken clamps and damaged earth pits.
- Documentation and drawings of the as-installed system.
Who it’s for
Where this work fits
Factories and warehouses
Large roofs, tall structures and sensitive process equipment all need a considered strategy.
Telecoms, solar and EV sites
Exposed sites where surge damage to expensive equipment is the main risk.
Schools, mosques and public buildings
Protection for occupants and structures that gather many people.
Homes in high-risk locations
Hilltop, open-field or tall-structure homes that have suffered strike damage.
How we work
From survey to handover
Site review
We study roof, structure, services and any earlier strike or surge damage.
Risk assessment
Where required, the risk assessment is carried out by our specialist partner, who defines the protection level.
Installation
Air terminals, conductors, earthing and SPD installed to the agreed design.
Test and certificate pack
Earth and continuity tests recorded, drawings issued and the system documented.
Risk assessment
Risk assessment by a specialist partner
The formal lightning risk assessment, which decides whether protection is needed and at what level, is carried out by a specialist partner. Elektrika handles the electrical and installation side — conductors, bonding, earthing, SPD and testing — so the design is built correctly. See our lightning risk assessment guide for how the process works.
