High Quality Surge Protectors for Coaxial Systems

Since the dawn of time, thunder and lightning were thought to have been a sign of the Gods anger. The Greeks feared Zeus' lightning, the Romans experienced the wrath of Jupiter and with the old Teutons the God of Thunder, Thor, ruled.

Today, thunder and lightning can be explained as purely physical phenomena. As storm clouds gather, voltage increases within the clouds and between the clouds and earth. Once the potential difference finally reaches a limit of roughly 30,000 volts per centimetre there is a sudden discharge in the form of lightning and currents of 20,000 to 400,000 amps flow. In a split second the air is heated up to roughly 30,000° C. As a comparison the sun's surface temperature is only approx. 5,500 °C.

That is an enormous amount of energy with considerable potential to cause destruction. Damages not only result from a direct hit but also due to the potential differences of electrical systems or electromagnetic induction.

At the same time, the miniaturisation of electronic components results in increasingly greater sensitivity to surges. Even the tiniest impulse energies are enough today to cause irreversible damage. The costs of this kind of damage are not only toted up by the replacement of affected components but are also apparent in lost turnover during downtime and users' dissatisfaction. This is why lightning protection should also and particularly be paid special attention in modern telecommunication systems. For this, SPINNER offers its customers a high quality range of surge protectors for coaxial systems:

Gas discharge protectors for broadband applicationLambda/4 short circuit lines for RF outputs and low intermodulation valuesLambda/4 short circuit lines and gas discharge protectors combined (hybrid technology) for feeder lines with DC feed and AISG signals

Our surge protectors stand out in particular due:

Low VSWR and low insertion loss over the whole frequency rangeHigh protection effect by reduction of the residual voltage and energy to a value close to zeroHigh DC voltage and current ratingVery low passive intermodulationHigh RF-DC isolationSimple replacement of the gas discharge protector

Thanks to a new range of SPINNER surge protectors with a housing made of seawater resistant aluminium we can offer our customers a significantly lighter weight version with just as good electrical and mechanical features. Lower transport costs, easier installation or lower mast load are just a few of the advantages of our aluminium design. The electrical conductivity of aluminium, twice as high as brass, results in an even better surge current discharge.

Surge protectors from SPINNER significantly contribute to preventing downtime in telecommunication systems and to reducing maintenance and repair costs to the lowest level possible.
