The life of a coaxial cable depends on many factors. Some of
those factors are ultra-violet exposure, migration, high humidity,
age, corrosion, power/heat, and voltage. Here are some important
guidelines to remember when you start considering the replacement
of your coaxial cable run(s).
- Ultra-Violet exposure breaks down the plasticizers of
the jacket over time. As a guideline: Type IIa (2a) non-contaminating
PVC jackets can last twice as long as type Ia (1a) PVC jacket.
- Migration & Corrosion affects the attenuation stability
over time by contamination of the dielectric due to jacket plasticizers,
and moisture penetration through the jacket.
- Power electrical losses result from the generation of
heat in the center conductor; braid shield, and the dielectric.
The power handling capability of a cable is related to its ability
to effectively dissipate this heat. Please be aware that a solid
or semi-solid polyethylene dielectric dissipates heat better than
a foam polyethylene dielectric, since most of the heat
is generated in the center conductor. On balance, the power handling
capability of a coaxial cable is inversely proportional to its
attenuation, and to its size. This is why RG213/U (CABLE X-PERTS
# 18267) handles higher power more efficiently than for example
RG58/U (CABLE X-PERTS # 18240). Another factor is the thermal
conductive (or heat transfer) properties of the cable, especially
within the dielectric. In other words, high ambient temperature,
and high altitude could reduce the power rating by impeding the
heat transfer out of the cable. High VSWR also reduces the power
ratings due to localized HOT SPOTS at poor connector terminations
and/or other improper usage.
- Operating Voltage is represented by two separate voltage
ratings.
- Corona is a related ionization phenomenon that causes
noise generation, which leads to long term dielectric damage,
and eventual breakdown of the cable. Note: High wattage amplifiers
can cause premature dielectric deterioration and larger Corona
affects.
- Dielectric Withstanding Voltage a voltage level that
abruptly breaks down the dielectric. To ensure the dielectric
integrity of CABLE X-PERTS cables and assemblies, they are
HI-POT™ tested during manufacturing and in our ready-made
cable assembly department.
|
�In summation, coaxial cable can perform to it's maximum designed
efficiency an average of seven years to ten years, provided the
connectors are appropriately terminated and the cable is installed
correctly.� So if your signal is fading or you're getting
erratic VSWR readings, or are unable to get the maximum performance
from your transceiver, then its time to consider changing your coaxial
cable or cable assemblies. To help choose the correct cable for
your application, use our handy
Cable Calculatorand visit our Ready-Made assembly
product page. Otherwise, simply contact our sales department for additional help in making your
cabling choices. |
