Grounding for tower lightning protection systems more than just low ground resistance. For the buildings ground system the main electrical wire entry already has a copper stake driven into the earth.

Lightning Protection Products For Communication Towers Lec

The bonding should be wide flashing using either high temperature silver solder or cad welding to the ground rods.

Grounding towers for lightning protection. Grounding does not prevent lightning strikes. The towers as well as the facilities themselves are protected from lightning strikes by robust all-copper grounding systems. A second copper stake driven into the earth for the signal carrying wires is a separate earth ground system.

Static Dissipators and Grounding Towers For Lightning Protection. A Spline Ball Ionizers SBI - The patented SBI is a hybrid lightning protection concept engineered to provide multiple layers of protection for critical applications. Multiple PLP-32 masts may be used to protect extended areas.

It reduces the chance of the cable shields and control wires from being the sole path from a lightning strike. A self-support tower should be grounded at every leg of the tower. With typical current levels rising to anywhere between about 3 000 and 140 000 amps it is hardly surprising that anywhere that receives a direct strike is damaged.

The term listed refers to products that have been. Antenna discharge units are known by many names including lightning protectors lightning protection devices surge arresters and surge protection devices. Visualize a tower site and imagine a 150-foot radius sphere representing a step leader typical jump rolling over all outlined objects everywhere the.

Lightning is an awesome naturally occurring event that causes thousands of injuries and deaths as well as billions of dollars in property loss annually. Using two different earth ground systems for lightning protection is as bad as having no lightning protection at all. One of our friendly staff members will explain communication tower lightning protection oil tank lightning protection and petroleum lightning protection.

Other requirements lightning protection may be the most complex aspect. A description of lightning is presented to familiarize the reader with the phenomenon and define the problem of lightning protection grounding. Taken over the lifetime of typical tower and antenna systems there is meaningful risk worldwide and it makes sense to at least minimally protect facilities outside of lightning belts.

The surge arrester is grounded by running a 10 AWG copper or aluminum wire from a metal lug inside of the arrester to one of the grounding connections mentioned above.

Though unpredictable lightning is a very common event around the world.

So if it is a triangular tower that means three straps running from the tower leg to your grounding system. Certainly the lightning phenome-non is a complex subject in its own right and one under continual scientific study. While the incidence of lightning strikes varies virtually all populated regions have some lightning exposure hazard.

Been advocating in their Lightning Protection Code NFPA 780 that a 45-degree cone angle from the top of the tower towards the earth does not describe an effective protection area. There are many dramatic photographs of lightning striking tall buildings or even just striking the ground. In its primary mode the SBI lowers the risk of direct strikes by utilizing a phenomenon known as charge transfer where a well-grounded point exchanges ions between the air and earth.

ERICOhas complete telecommunications applications solu- tions to help protect the facility against electrical noise lightning induced surges and transients caused by switching components in the power systems. The lightning strike can have a very destructive effect. In areas of intense lightning risk extreme protection measures are mandatory.

Groundingearthing lightning protection and surge protection are critical parts of a telecommunications facility installation. There are many models of surge arrester available but unfortunately arent likely available in local hardware stores. When grounding a tower with Cu conductor.

With towers sitting on rock obtaining low ground resistances was a huge challenge as well as an environmental issue in this urban location. Bonding and grounding are extremely important to dissipate lightning strikes. You can also schedule an initial.

800 749-6800 and set up an appointment today. Grounding connections from antennas cables and shielded wave guides on the tower are made to a ¼-inch thick copper grounding bar affixed to the tower steel about 10-feet above grade Figure 7. Guyed towers make grounding a little bit easier since the guy wires tend to divide up the electrical energy of a lightning strike.

PLP-32 Lightning Masts provide a cone of protection within which lightning charges are diverted to the mast and grounded instead of to the protected object. Protected areas may be determined by use of the widely accepted rolling sphere concept. Acceptable lightning protection with shield wires is dependent on obtaining a low value for tower grounding resistance.

Tower grounding The green area is where most lightning current passes. Mast- or tower-mounted amplifiers and other outdoor electronics associated with the antenna system.
