A metal rod placed on top of a building to protect it from a lightning strike is known as a lightning conductor or lightning rod.

It provides a harmless and easy path for the lightning energy to pass into the ground without damaging the structure of the buildings. The “path” or the earthing system is installed from the top to the bottom of the building.

Most lightning protection systems are interception systems that don’t reduce the odds that lightning will strike a building.

Do you know that due to advancement in technology, there is a type of lightning rod protection that actually dissipates lightning from the area of protection? In other words, it prevents direct lightning strikes by reducing the electric field to below lightning-collection levels, within the protected area. As a result, DAS helps to prevent downtime and loss of assets, while increasing safety.

Engineered to integrate with any building, rig, tower, tank, stack or other structure, DAS technology has been in use since 1971. With over 3,000 systems installed worldwide, accruing over 50,000 system-years, DAS maintains a success rate over 99% and continues to protect thousands of sites without incident.

DAS is a cost-effective means of reducing expenditures for damage due to lightning. A properly designed, constructed and mounted lightning rod protection can help save money. It should be remembered that installation of a DAS system is not a stand-alone solution.

DAS is a key component of the advanced lightning rod protection system.  Additional components include grounding and surge suppression to achieve complete protection.

A typical system includes:

  1. The Dissipation Array System (DAS): available in a range of configurations for almost any structure.
  2. Chem-Rod: a low-impedance grounding system using chemically-charged electrodes
  3. Surge Protection Devices (SPD): to protect against transients traveling through data lines and other conductive paths.
  4. Spline Ball Ionizer (SBI): a modular strike prevention device, as needed to supplement the DAS area of protection.

DAS is based upon LEC’s patented charge transfer technology, and is based, is a distinct split from Franklin rods.”

LEC enjoys a worldwide reputation as a foremost specialist in lightning rod protection and we have also proven our commitment to research and development.

We are devoted to offering a truly effective system and design, providing the highest level of safety and effectiveness in lightning rod protection.
