Qing Cables offer a range of cables designed for use on CCTV, Broadband Systems, Cable TV, MATV, and quality satellite reception. They are manufactured in accordance with EN50117 standards.
The cables are designed to work at frequencies in excess of 2000Mhz, whilst offering excellent attenuation and RLR figures.
The construction is Gas Injected Foam with a longitudinally overlapped copper tape and plain copper braid, facilitating good bending radius characteristics and very efficient screening in areas with high electrical noise presence.
Whilst the popular DFD100 is available in Black, White or Brown PVC sheath, larger sizes are Black PE (polyethylene), which gives improved durability and a higher level of protection, not only to water and humidity, but also to oils and some solvents. The black carbon substance in PE increases the cables’ resistance to ultraviolet rays.
The range is manufactured to meet the stringent CAI Construction / Performance criteria, so digital compatibility is assured.
Other sheath options available are: LSZH (Low Smoke Zero Halogen), DB (Direct Burial)
Lower grade 5 Cell versions are also available in a limited range suitable for CCTV where high frequency transmissions are not used. The range also includes Direct Burial Grade options.
DFD100X2 – Twin DFD100 in a Fig.8 / Shotgun formation
DIG5/E – 5x DFD100 + 4.0mm² Earth
LOW SMOKE EMISSIONS
Many local authorities and government bodies specify that cables installed must be of “Low Smoke and Fume” (LSF), or “Low Smoke Zero Halogen” (LSZH) construction. LSZH types are available from stock.
DIRECT BURIAL (DB)
Where a situation calls for cables to be buried, the DB range offers a cost effective, rugged solution. These cables have a double sheath construction, the inner of polyethylene, and the outer polypropylene giving a very robust finish. This sheath also has very low abrasion properties making it easy to pull into ducts.
THE DBF RANGE CARRIES A 15 YEAR GUARANTEE
Where extremely long external / ducted runs are required QC125S is an ideal replacement for RG59. This cable has a UV Stabilised Polyethylene (PE) sheath.
DIRECT BURIAL (DBX)
Where a situation calls for cables to be buried, the DBX range offers a cost effective, rugged solution. These cables have a double sheath construction, the inner of polyethylene, and the outer polypropylene giving a very robust finish.
