Last week, the editor published an article about an outdoor LED street light factory in Shenzhen on the public account. Because the number of orders exported to Brazil in South America was relatively large and the unit price was low, we were "forced" to use our LED driver-free solution. , greatly reduced the cost, and successfully harvested the story of a large order from Brazilian customers. Afterwards, someone contacted the editor and said: After two years, two lightning arresters are still damaged? How do you explain this please? In this regard, the editor asked him to read...

How to identify the material of the waterproof junction box? If you burn it, it will damage the box. Then we choose simple identification. PC has the best gloss, ABS is the second, and PP is slightly worse. Looking at the weight and texture, PC of the same specification is the heaviest, ABS is the second, and PP is the lightest....

The landmark buildings and scenic spots of the modern city image have a profound impact on the colorful lights at night. Lighting is also one of the important infrastructures of the city. How to ensure a more reliable and safe operation in the outdoor environment in a complex and changeable natural environment is the most critical requirement of landscape lighting. Shenzhen Greenway Electronics‘ M series waterproof connectors are becoming an important choice for urban landscape lighting project connection solutions due to their high waterproof and corrosion resistance in harsh environm...

Waterproof junction box is an auxiliary material for electrical accessories, and its main function is to protect cables and connect wires. Waterproof junction box is generally composed of shell, top cover, waterproof silicone gasket, waterproof joint and connection terminal. The function is to prevent water stains or water-related ground burial or contamination from invading the inside of the junction box and ensure good electrical contact performance....

Low voltage lightning arrester is an internal lightning protection scheme. The internal lightning protection system is based on shielding, equipotential, limiting, metal conductor shunt and choke type routing arrangement grounding and other measures. Lightning produces instantaneous high voltage current limiting and shunt from all aspects. The main function of low-voltage power supply lightning arrester is to import the grounding body instantaneously under the impact of lightning wave, so as to minimize the residual voltage on the line behind the lightning arrester to protect the safety...

Difference between the two Overvoltage protector has no effect on lightning, and arrester is not sensitive to overvoltage. Overvoltage refers to the supply voltage is higher than the equipment can withstand the voltage limit, such as operating overvoltage, light load overvoltage during trough period, or accident overvoltage. Overvoltage will damage electrical appliances, ‘ overvoltage protector ‘ is to prevent this kind of overvoltage damage. Lightning arrester is the equipment to prevent lightning disasters. Lightning and overvoltage are different. Lightning voltage is very high,...

Outdoor lamps have wall washing lamps, shooting lamps, buried lamps, fountain lamps, lighting lamps, courtyard lamps, plant lamps, street lamps and so on. Usually, the core issue of these outdoor lamps is safe electricity consumption. Lamps need protective measures when wiring.
