TerraStreamer®

TerraStreamer® ESE Terminalsare the preferred protectionmethod for mega-structuressuch as distribution warehouses,industrial plants, amusementparks, shopping malls, sportsarenas, golf courses, andother large area structures. ESETerminals are tested towithstand a minimum electricaldischarge current of 100 kA.

Early Streamer Emission (ESE) Terminals

Extensive research and development has allowed AlltecCorporation to create a lightweight and low wind loading ESEsystem to provide a safe and efficient manner of controllingdangerous lightning energy before it damages structures or itsimportant contents, including human occupants. By utilizingadvanced technology, TerraStreamer® ESEs provide lightningprotection to facilities that would otherwise be difficult or costprohibitive to protect by conventional means.

The TerraStreamer® ESE Terminals are externally mounted,proactive, structural lightning protection devices and aredesigned to activate in the moments directly preceding animminent direct strike. The installation of a TerraStreamer® ESETerminal combines the best advantages of two systems: thedirect path to ground of a conventional lightning protectionsystem, and state-of-the-art ESE technology employed in theTerraStreamer’s internal design. These combined advantagesensure that the TerraStreamer® ESE System provides a securezone of protection.

TerraStreamer® ESEs are made of non-corrosive materials,utilize advance and sustainable technologies, maintain a 5-yearreplacement warranty, and are independently tested certified

to NF C 17-102 and UNE 21 186 standards. TerraStreamer®products complete the Alltec Protection Pyramid bycapturing dangerous lightning discharges and safelychanneling it to earth.

The ESE Principle

The principle of operation for ESE terminals is to create anupward propagating streamer earlier than conventional airterminals or other objects on the earth. TerraStreamer® doesthis by collecting and storing ground charge during the initialphase of a thunderstorm development.

Once a thunderstorm begins creating downward step leaders,the ambient electric field intensity in the area of the ESEterminal increases. When this electric field intensifies, it triggersthe terminal to release the stored ground charge, forming anupward streamer microseconds earlier than other objects inthe immediate area.

This development of an upward streamer earlier in time andspace ensures that the TerraStreamer® ESE terminal will be thetarget of the developing lightning strike. The selection of theTerraStreamer® model, placement, and mounting height abovethe protected area all factor into formulas calculating thedimensions of the protection area.

FRP M A S TAlltec Corporation FRP masts are comprised of a combination ofa polymer (plastic) matrix and glass fiber reinforcement materials.Such composites provide a wide range of desirable mechanicalproperties and durability including: exceptional tensile, flexural,impact, and overall compressive strengths. This makes Alltec’s FRPsystem ideal for use in mast supports for Early Streamer Emission(ESE) lightning protection systems and other significant uses.

FRP is a nonmagnetic material which is nearly transparent toradiated electromagnetic energy such as radar. Additionally, studieshave shown that the environmental impacts, including energy costsand pollutants, are significantly reduced for FRP manufacturingover steel.

Alltec Corporation FRP masts are specially designed to supplymore strength per unit of weight than most metals; they areinherently resistant to corrosion and galvanic effects. FRP mastsdo not rust and are formulated to provide long-term resistance toall environmental chemicals and temperature extremes, includingsaltwater ocean spray. Wind causes fatigue loads, where FRP hasproven to far outperform that of standard steel masts. Increasedservice life and decreased maintenance costs are key features inchoosing FRP masts.

Lightweight construction and simple assembly means thatinstallation may be done faster and with less manpower.

FEATURES INCLUDE:

s Rapidly deployables Designed to outperform traditional steel mast systemss Mast kits come complete with a variety of optionss Decreased maintenance costss Corrosion resistants Aesthetically pleasings Intended to withstand environmental, chemical, and

temperature extremes

FRP Mast products are a key component of Alltec Corporation’sProtection Pyramid™, a three-tier program to success forcomprehensive facility protection to keep sites and systemsoperating safely and reliably.

Lightning Strike Counter

The ASC-6X Lightning Strike Counter is designedto monitor occurrences of lightning strikes tostructures and outdoor equipment. At any moment,there are almost two thousand thunderstorms inprogress all over the world. About 100 lightningbolts strike the Earth every second, and eachinstance poses the prospect of damage to sensitiveelectronic equipment, facilities, and people. Theability to automatically count and record thesestrikes provides valuable information to enhancelightning protection security as well as supplementinspection and maintenance procedures.
