K26 LSZH 50/75Ω Coaxial Cables
Application
The 50Ω cables are HF transmission coaxial cables for GSM antennas, and the 75Ω cables are HF transmission
coaxial cables for cameras (type KX6), and video surveillance (type 11 RTC). The Halogen-free cables are
suitable for laid on hooks, and pulled through walls or through technical ducts.
Standards
RATP K26
Fire Performance: NF C 32070.2.2
Construction
Inner Conductors
50Ω cables:
Flexible Type (F)- solid copper coated aluminium (for 1/4″ , 3/8″ &1/2″ F conductor); red copper tube (for
7/8″ and 1'1/4 F conductor); corrugated red copper tube (for 1'5/8 F conductor).
Super Flexible Type (SF) - solid copper coated aluminium (for 3/8″ & 1/2″ SFconductor); helical corrugated
copper tube (for 7/8” SF conductor); copper wire (for 1/4″ SFconductor).
Extra Flexible (XF) – copper wire (for 1/4" XF conductor); solid copper coated aluminium (for 3/8" XF
conductor).
75Ω cables: solid red copper (for type 11 RTC) or red copper tube (for type KX6).
Dielectric
Cellular PE or natural PE (only for KX6 type).
Outer Conductor
50Ω cables: corrugated copper tube.
75Ω cables: copper braid.
Outer sheath
LSZH.
