5G communication equipment (including antenna unit,various power amplifier module RRU unit, ODF unit box, cabinet
duplexer/cavity filter, wireless base station optical fiber box)Based on e-PTFE protection and ventlation, SDA Shangda waterproof ventilation valve can provide an effective waterproof and dust-proof barrier for 5G communication equipment.
the rapid development of 5G networks,the increasing adoption of small celltechnology means that telecommunications infrastructureand electronic components are becoming increasingly sophisticated and complex. However,for communication equipment exposed tothe outdoor environment, any of extreme changes in temperature (sunny to heavy rain),continuous heating and cooling cycles ofinternal heat sources will cause pressure differences to develop within the sealed housing. And often bear the influence of outdoortemperature fuctuations at any time,forbidden by wind and rain,frost and snow cover and sunlight exposure, equipment is easilydamaged, seriously afecting the transmission of information. The performance of the communication equipment is reduced, resutingin greater maintenance or repair costs.

the use of SDA Shangda waterproof ventlation valve can ensure that communication equipment is protected and working propenly,its
advantages include
1. Maintain a stable connection;, 2.Reduce maintenance;3. Reduce manufacturing costs; 4. Meet equipment life expectations; 5
Improve integration and automation.

5G communication equipment is based on the e-PTFE protection and ventilation scheme (using the characteristics of waterproof
ventilation valve):
1., Equalizing Pressure: Reduces the strain of the I P65 rated (or higher) enclosure seal by equalizing pressure to allow flowing airto continue through the breathable membrane.
2. Prevent contamination: Continuously shield contaminants such as liquids, insects, salt, sand and even dust to protect sensitive
electronic components and improve their stability.
3. Reduce condensation: Allow water vapor diffusion, as far as possible to reduce condensation,thereby increasing the poweroutput of the equipment and reducing the damage of internal components.
4. Easy integration: Avariely of designs and sizes, including threaded, snap-on and adhesive-backed constructions, can be easily
integrated into any housing design.
