Product Solutions
Lightning Protection
When planning and executing a lightning protection system, it is necessary to observe all relevant national annexes and take account of any special circumstances or applications and the safety stipulations in the relevant country-specific supplements.
SineTamer Surge Protector
Transient and Surge Protection
Power transients, voltage spikes, and electrical surges are the leading causes of equipment damage and downtime. Our SineTamer surge and transient protection technology safeguards your systems against these destructive power quality events.
Surge Protection Devices (SPDs) AC
Surge Protection Devices (SPDs) DC
Our DC Surge Protection Devices (SPDs) protect photovoltaic systems, battery storage, and DC-powered equipment from damaging transients, spikes, and lightning-induced surges. Designed for reliability and compliance, they ensure long-term system safety and uninterrupted operation.
Data Line Surge Protection
Earthing Material
A well designed earthing system is vital for any electrical installation to avoid the danger associated with fault currents to avoid step and touch
Market Segments
Lightning Protection for Solar PV Systems
Lightning is one of the most common causes of failure in photovoltaic (PV) systems. A damaging surge can occur even when lightning strikes kilometres away—or from discharges between clouds. These transient events can severely impact inverters, panels, and monitoring equipment. Fortunately, most lightning-related damage is preventable. BlitzTek offers some of the most cost-effective and proven surge protection devices, trusted by power system installers across South Africa and beyond. Our solutions are backed by decades of industry experience, ensuring reliable performance, compliance, and long-term protection for your solar investment.
Lightning Protection for Telecommunications Systems
Telecommunication networks are especially vulnerable to lightning strikes and transient overvoltages due to their extensive cabling, antenna structures, and outdoor installations. Even a distant lightning strike can induce damaging surges that disrupt communication signals, damage sensitive equipment, and cause costly downtime. BlitzTek provides advanced lightning and surge protection solutions specifically engineered for telecom infrastructure — including towers, base stations, data centers, and network facilities. Our systems ensure reliable signal integrity, equipment longevity, and continuous network uptime, helping you maintain seamless communication even during severe weather conditions.
Lightning Protection in the Mining Sector
In the dynamic and challenging environment of the mining sector, lightning poses a significant threat, capable of inflicting costly equipment damage and operational delays. At BlitzTek, we understand the critical nature of protecting your mining operations from the unpredictable forces of nature. Our advanced lightning protection solutions are specifically designed to withstand the rigors of mining activities, ensuring that your valuable machinery, control systems, and data remain safe from transient surges and lightning strikes. With our expertise and innovative products, you can focus on productivity and safety, knowing that your mining infrastructure is shielded by comprehensive lightning protection measures tailored to your unique needs.

Risk Assessments
A lightning risk assessment is a detailed study that measures the likelihood of a lightning strike and the potential for damage to your facility. At BlitzTek, we assess lightning risks according to the IEC 62305 international standard, ensuring every design meets global compliance. A thorough risk assessment is the first and most important step in planning and installing effective external and internal lightning protection systems.
Site Surveys
Our professional on-site surveys are essential for maintaining your Lightning Protection System (LPS) and identifying any weak points in your current setup. We evaluate the structure, grounding systems, and overall site conditions to provide targeted solutions that prevent further damage and ensure long-term operational safety.
Engineered Lightning Protection System Designs
Our expert engineering team designs custom lightning protection systems that meet international and local standards. A correctly designed LPS safely captures and directs lightning energy to ground without attracting strikes unnecessarily—protecting both people and property with precision-engineered reliability.
Lightning Protection System Verification & Certification
We perform verification, inspection, and certification of both internal and external lightning protection systems. Regular testing and certification ensure your installation remains compliant, effective, and fully operational, providing peace of mind and ongoing protection for your facility.
