Advanced Features:
Presented below are key features of RG Series which are widely
represented in different versions within this catalogue.
All of these products have some common features including:
--Closed cell Foamed PE Dielectric
--Attenuation Swept from 5MHz-2GHz
--High screening effectiveness, also know as Class A+/ Class A++
Screen Attenuation(AS) according to EN50117 SPECIFICATIONS
--Long-lasting stability of signal attenuation thanks to physical gas injected foam PE dielectric technology(skin-foam-skin)
--Coaxial cables with PVC Jacket, flexible thermo-plastic material commonly used on general purpose
coaxial products. Temprature rating:-40℃ to 80℃
--Coaxial cables with PE outer sheath, strong enough to protect the coaxial core from the environment,
must be used for outdoor / underground/ direct burial
installations. Temprature rating:-55℃ to 85℃
--Characteristics of LSZH: flame and fire retartant, low smoke and
fume emission, zero halogen and UV resistant

How to choose the right coaxial Cable－Material
1 Inner Conductor
SC(Silver Copper)
TC(Tined Copper)
BC(Bare Copper) or called CU have a good electrical performance and
flexibility
CCA(Copper clad Aluminum) very Light but could be easier
oxidized(rusted)
CCS(Copper clad steel) Cheap(price only 1/5 of BC) and not bad
electrical performance
the cost is Silver copper>tinned copper>bare copper>Copper
clad aluminum>Copper clad steel
2 Insulation
Solid PE/Foam PE/ Gas Injection PE
Currently there is two type of PE in the market for the Drop
Cables,
Local PE(Chinese Manufacture)
Imported PE( DOW chemical..)
The main difference of the two type, is that Local PE is not pass
the Oxidative induction time(OIT) Test, and the Crush resistant
Test, which may required by the CATV company, but general the
electrical performance is the same.
The price difference of the material is about 23%...
3 Foil Screen
Normally it is in three type
AL or copper foil not bonded to the insulation ---AP
AL or copper foil bonded to the insulation- Bonded Al/Pet(blue)-
BAP(the most widely used)
AL/PET/AL foil bonded to the insulation- Bonded Al/Pet/AL- BAPA
I have meet some customer that want a copper color Al foil(some
clients called golden foil), which is the same color of the copper
foil, but it is Al foil. WOW--a lot lot cheaper,, scratch on the
foil, you will see or burn it.
One more thing is the overlap of the foil, >2mm or >20%, you
need to know from your supplier
4 Braiding
For the braiding wire, there is:
BC Copper wire,
TC Tinned copper wire,
SC Silvered copper wire,
CCA Copper clad Aluminum wire, looks like BC but could be easier
oxidized(rusted)
AL Magnesium Aluminum Wire, (the most widely used)
the cost is Silver copper wire>tinned copper wire>copper
wire>Copper clad aluminum wire> Aluminum wire
With a knife or lighter you can tell the difference
Another difference of the cost, is the braiding coverage, form
30%-95%, normally in the market is 48%, 60%, 77%, for the digital
cable, is over 90%.
5 Jacket
The requirement for PVC included
1 Tensile strength before aging
2 Elongation before aging
3 Tensile strength after aging
4 Elongation after aging
5 Shrinkage
6 Heat shock
7 Cold bend
8 Cold Impact
9 UV Resistant
10 Fire resistant( include different grade, for north american
market, there is CMX,CM,CMR/Riser,CMP/ Plenum, for European, it is
IEC60332-1, IEC 60332-3, IEC60332-3C)
The more requirement you need, the more expensive the material.
For the Tropical area, you might just need the 1,2,9, and that would be enough,
For the cold area, you might need the 7, 8, but still you need to know your lowest
temperature, other wire, the jacket will be break, and you have to
reinstall, or get the customer complaint.
For commercial building , first resistant CMR, CMP is recommend.
For the fire resistant PVC , it is better to get the certification
online check like UL/ETL, if they pass, you can find the relevant
information of the company. and you might need to send it to test
like half a year or once year from the mass production to be more
sure.
If you have technical support from an engineer, please let us know
the type of cables you need, the inner conductor, the braiding
coverage, the jakcet material and color, the packing length and
design, and the application. We will help you choose the most
suitable cable.
If you are not sure about certain specifications of the electric
cables, please let us know your inquiry and we are very happy to
give you professional technical advice and support services. Our
company offer specific cables and wires consulting, design, OEM and
manufacturing based on the customer's requirements and application
scenarios to help customers create more business opportunities.
