(Summary description)Mobile communication technology represented by 5G is being closely integrated with AI and big data, opening a new era of interconnection of all things, and will become the most important technological direction in the next decade. Then 5G communication equipment such as antenna units, tower top electronic equipment, base station power supplies, small base stations, tower top sensors, digital remote systems, cabinets, ODF unit boxes, RRU units, etc. are getting higher and higher protection. For the requirements of dust and high temperature resistance, the waterproof and breathable products developed by PUW Puwei Company for 5G communication equipment have been well recognized, and mainly have the following characteristics: 1. Balance pressure relief: PUW waterproof and breathable products relieve pressure through balance, allowing the flowing air to pass through the waterproof membrane to reduce the stress of the shell seal. 2. Water and dust resistance: PUW waterproof and breathable products can continuously block liquids, insects, salt, sand and other pollutants, protect sensitive electronic components and improve their stability. 3. Convenient installation: PUW waterproof and breathable products have a variety of designs and sizes, including threaded, snap-on and adhesive-backed. Can be easily installed in any housing design. 4. Reduce costs: PUW waterproof and breathable products extend the service life of the product by balancing pressure relief, blocking water and dust, without the use of stronger sealing rings, additional bolts or other fixing solutions. 5. Industry standards: PUW waterproof and breathable products have been tested for reliability to meet extremely harsh environmental applications. The products have passed ISO9001 certification. The PUW protection products used in 5G communication equipment are as follows: IPX7 waterproof membrane IPX8 microporous membrane PAM12*1.5-10 PUWM12*1.5-10 PAM5*0.8-4
