The technical parameters of leaky cables mainly include key indicators such as electrical parameters, mechanical and environmental characteristics.
Key electrical parameters include characteristic impedance, voltage standing wave ratio (VSWR), longitudinal attenuation, coupling loss, operating frequency band, and polarization. The characteristic impedance is 50 ± 2 Ω. The VSWR has specific maximum values in different frequency bands. Longitudinal attenuation and coupling loss vary with frequency. The operating frequency band can cover 400MHz-6GHz.
Mechanical and environmental characteristics involve parameters such as reference weight, maximum tensile force, bending radius, operating temperature range, and minimum installation temperature. The reference weight ranges from 610kg/km to 830kg/km, the maximum tensile force is 2000N or 2500N, and the operating temperature range is typically -55℃ to +85℃.
For example, a 1 5/8" radial leaky cable (model RFXT 1 5/8" -50M/H) has a characteristic impedance of 50 ± 2 Ω, a reference weight of 830kg/km, and a maximum tensile force of 2500N.
The 1 1/4" radial leaky cable (model HLRHTCYZ-50-32-H) has a characteristic impedance of 50 ± 2 Ω, a reference weight of 610 kg/km, and a maximum tensile strength of 2000 N.
Relevant testing standards include IEC 61196-4, and management system certifications include ISO 9001, ISO 14001, and ISO 45001.
