1. In order to reliably prevent lightning strikes, an antenna lightning protection device can be serially connected to the output end of the antenna and the input end of the protected device. In areas where there is less thunder and lightning, the antenna can be used with only one amplifier.
2. The effectiveness of a coaxial surge protector depends largely on its installation, especially its connection to the grounding grid. The following points must be strictly observed:
Equipotential grounding network: All installed protectors must be connected to a single grounding point (or grounding grid) to optimize the connection between the surge protector and the grounding grid: to minimize residual voltage caused by surge discharge current, grounding grid The wiring must be as short as possible (less than 50CM), the cross section of the grounding conductor should be as large as possible (minimum 4mm2), the other end should be reliably connected with the grounding bus of the lightning protection system, and the “straight-through†installation can be selected (direct mounting on the flange is used Grounding plate) Position of the protector: Optimally installed at the inlet side of the line (limits the inrush current inflow) and near the sensitive equipment (improved protection effect)
3, in the use of outdoor antenna lightning protection must pay attention to water, must not let the rain immersed in its internal corrosion damage.
4, this product does not require special maintenance. When the system operation fails, the lightning protection device can be removed and then checked. If the system returns to normal after the lightning protection device is used, the lightning protection device is damaged and must be replaced immediately. Those who have conditions may periodically check whether the nominal voltage of the lightning protection device for antenna feeders meets the requirements of the indicator. If they are already out of tolerance, they must be replaced.
This Plastic Peripheral Machine Series
includes fully automatic edge recycling system, stainless steel mixer, strong
granulations, chiller and so on. These are some optional spare parts for the
stretch film machine, they are simple, easy to operate, it will be perfect
together with the stretch film machine, comes true one-stop production line.
On-Line Edge Recycling System:
To recycl the edge film when the stretch film machine is running , it is easy to operate, save power and material, achiece recycling use.
Stainless Steel Mixer
Helical circular mixture fast and equal
stiming, suitable for all kind of plastic raw material;
Installed with power control device to
ensure safety;
Drying & mixing type is available
(optional).
The strong Granulator
Tailored to meet a wide variety of requirement,
able to granulating & recycle all kind of plastics material with different
texture and shapes.
Chiller
Used for cooling the water inside the
cooling roller, it has wind cooling and water cooling two types. The chiller
can help the water in a constant temperature, keep the cooling surface same temperature,
to make the film more beautiful.
Air Compressor
Air compressor is a compressed gas equipment, which is the main source
device, the compression of air pressure generating, can make the mechanical
energy of original motivation (usually a motor) convert into gas pressure
energy.
