This Q&A answers some common questions you may ask, we hope this may help you in selecting our product.

Q: What Are Sanyuan's Lightning Protection Devices?

A: Sanyuan's lightning protection devices including lightning rod, surge protector device (SPD), surge arrester, and other accessories.

Q: What Are The Differences Among These Products?

A: Under normal circumstances, the lightning rod is used for the protection of the building frame. The SPD is used for the place that may be directly affected by lightning, to prevent lightning from going into the equipment. Surge arrester can be seen as a special kind of SPD, for its protection ability is low, and generally cannot suffer a lightning strike directly. Surge arrester is usually used as a supplement SPD in case the main SPD in the circuit does not eliminate the entire lightning wave. It can be used to prevent a small surge produced from high power equipment start and stop, equipment short circuit, or electromagnetic induction. Since the SPD would be directly hit by lightning, it must have sufficient insulation performance, and the size is relatively large. The surge protector does not requires a high surge protect performance, and can be customized according to different needs. The size of surge arrestor is usually smaller than SPD.

Q: What Kind of Sanyuan Product Should I Choose?

A: It depends on your specific needs. You can consult your local meteorological department to obtain historical lightning data, or investigate surrounding buildings for the history of lightning strike, to calculate the approximate intensity of possible future lightning. After take consideration of specifications of other sub-components, select lightning protection product with the best performance according to the data you gathered.

2. The main feeder cable should be grounded before entering the room. After through the feeder window into the room and connect with the indoor communication equipment, it should be installed with a surge arrester.
3. Indoor equipment should be grounded and have power arrester installed at the input.
