Cable design KSR240 (TZC 500 25)
KSR240 Low Attenuation Coaxial Cable (TZC 500 25) is similar in size to RG-58 cable but has lower attenuation and better shielding. These improvements are achieved by using a foamed dielectric and double shielding.
constructively cable KSR240 consists of:
– central conductor: solid copper core with a diameter of 1,42 mm
– Internal dielectric made of foamed polyethylene with a diameter of 3,81 mm.
– the first shielding layer made of aluminum foil
– the second shielding layer – braiding of tinned copper with a diameter of 4,52 mm
– Outer protective shell made of polyethylene (PE) with a thickness of 0,8 mm and a diameter of 6,10 mm

Mechanical characteristics of KSR240 cable
Installation temperature range: -25...+70ºС
Storage temperature range: -55...+85ºС
Operating temperature range: -40...+85ºС
Minimum bending radius: 19,1 mm
Re-bending radius: 63,5 mm
Packaging and labeling
The cable is securely packed on a wooden drum. The standard of packaging is 500 m.
KSR240 cable can be cut to shorter lengths upon request.
KSR240 is similar in size to the following widely used types of HF coaxial cables: LMR 240, MRC 240, WBC-240, WCX 240, SPEEDFOAM 240, TZC 500 25, HUBER+SUHNER S 04272 B.
The KSR 240 cable is slightly thinner than the 5D-FB or RK-50-4-11 cables, but at the same time, the choice of connectors for it is much wider.
