1.Application
 This series fuse is suitable for AC 50Hz, rated voltage to 1000V, rated current to 1250A. It is mainly used for protecting the electrical circuit against overload and short-circuits(gG/gL). Because of different melting tablets, it also may derive for protecting the semiconductor device and others complete set installment from short-circuit (aR/gR/gs/gtr) as well as the electric motor from short circuit (aM). The rated breaking capacity is to 120KA. They conform to national standard GB13539 and international electrical committee standard IEC60269.
2.Construction Feature
   This series of fuse consists of fuse link, fuse base and carrier fuse. The variable cross-section fuse body made by pure copper piece (or copper wire, silver wire, silver piece) is sealed in the square fusion tube which is made by the high strength porcelain or epoxy glass cloth pipe, there is full of the high-purity quartz sand processed after chemistry to take the extinguishing of arc medium in the tube. The two sides of the fuse use the spot welding to reliably connect with the end plate(or junction panel) and to form the square knife shape contact structure. The fuse may have fuse indicator or striker, when the fuse element fusing it can demonstrate fusing (indicator) or transforms each kind of signal as well as automatic transfer circuit (striker). The fuse base consists of high temperature resistance resin plate(or high intensity porcelain plate) and wedge-shaped static contact to form open-type structure and it can be used as the supporting device of the appropriate size of the fuse link. This series of fuse has many merits such as good in heat dissipation, high mechanical strength, reliable in contact, convenient in performance and so on.

The WiFi 6 Ceiling Wireless AP is a ceiling wireless access point based on the WiFi 6 (802.11ax) standard. It is a device designed to provide wireless Internet connectivity and can be mounted on the ceiling of a building to provide users with high-speed, stable wireless Internet coverage.
WiFi 6 Ceiling Wireless AP offers a number of advantages over previous WiFi standards such as WiFi 5, or 802.11ac. The benefits of WiFi 6 Ceiling Wireless aps and how they affect users are described in detail below.
1. Higher speed and capacity:
WiFi 6 Ceiling Wireless AP uses OFDMA technology (orthogonal frequency division multiple access), which can divide the wireless channel into multiple sub-channels, each sub-channel can transmit multiple data streams at the same time, improving the capacity and efficiency of the network. This means that the WiFi 6 Ceiling Wireless AP can deliver higher speeds and more stable connections to more devices at the same time with the same spectrum resources. For high-density environments, such as office buildings, conference rooms, or large event venues, WiFi 6 Ceiling Wireless AP can better meet users' needs for high-speed networks.
2. Low latency:
The WiFi 6 Ceiling Wireless AP uses Target Wake Time (TWT) technology to put devices to sleep at a predetermined time, reducing communication latency between devices. This is important for real-time applications such as video conferencing, online gaming, and iot devices. A low-latency network can provide a better user experience and support more real-time applications.
3. Better coverage:
The WiFi 6 Ceiling Wireless AP uses higher antenna gain and more advanced beamforming technology to provide wider coverage. This means that in the same environment, the WiFi 6 Ceiling Wireless AP can provide a more stable, longer distance wireless signal, reducing signal attenuation and interference, and improving network reliability and coverage.
4. Better power management:
The WiFi 6 Ceiling Wireless AP uses Target Wake Time (TWT) technology to put the device to sleep for a predetermined amount of time, reducing the power consumption of the device. This is important for battery-powered devices such as smartphones, tablets, and iot devices. Better power management can extend the battery life of the device and reduce frequent charging of the battery.
5. Better security:
WiFi 6 Ceiling Wireless AP uses stronger Encryption algorithms and authentication mechanisms, such as WPA3 encryption and Opportunistic Wireless Encryption (OWE) authentication, to provide better security protection. This is important to protect users' personal information and network data. The WiFi 6 Ceiling Wireless AP also supports more user isolation and guest management features to better protect the network.
In summary, the WiFi 6 Ceiling Wireless AP offers higher speed and capacity, lower latency, better coverage, better power management, and better security than previous WiFi standards. These advantages can provide a better user experience and meet the needs of users for high-speed, stable and secure wireless networks. Whether in the home, office or public space, WiFi 6 Ceiling Wireless AP is an ideal wireless access solution.
