Our Lightning protection systems have successfully been incorporated into a number of applications across all industries.


Facility structures

Having the best lightning conductors for capturing lightning on all facility structures is an essential first step in protecting your site. We use the best products, including Indelec industry leading Prevectron Early Streamer Emission air terminal . Using these lightning conductors and earthing equipment for grounding, gives the safest direct lightning path for facilities. One part of our complete solution is completing the LPS. We also incorporate power conditioners, surge protectors and uninterrupted power supplies for protecting internal devices vulnerable from indirect lightning.


Medical Equipment

The importance of having a constant uninterrupted power supply and power surge protectors for medical equipment is paramount for constant operation. We have the highest quality power conditioners, surge protectors and UPS equipment for giving Heath Services peace of mind during lightning strikes.


Data Protection

Protecting from the loss of data and damage to data storage facilities is becoming more important in our digital society. We offer a complete LPS for:

  • Data line protection
  • LAN/WAN protection
  • Signal Line protection
  • Telecommunication protection


We can supply some of the best UPS systems and power conditioner for data protection. There are a number of sectors depending on efficient protection against lightning strikes on large servers and facility structures such as banking/financial industry, government agencies, health authorities and emergency services.


Each of these authorities recognises data loss through power surges can have catastrophic consequences on their industry. We have the necessary surge protection devices, earthing equipment and power conditioners for protecting data in these industries.


Wind Turbines

There is an increase in using renewable energy for producing electricity; one method is using wind turbines. Wind turbines structural design and materials make excellent conductors. We use our specialist lightning conductors, surge protectors and earthing equipment for protecting against costly replacement of the turbine.


LDU Warranty Policy

We are confident our devices are reliable and robust for the harshest climates in Australia and surrounding international regions. In the unlikely case of any technology failure of your lightning protection devices, surge systems or UPS systems, we will replace the device in a professional and efficient manner; keeping your LPS working effectively.
