Different installation places for cables affects the transmission of signals through the cables. In order to make sure that the cables are less affected by environmental glitches it is important to design the cable according to its installation place. Overhead transmission cables generate losses due to skin effect, capacitance and inductance but are able to withstand harsh climate conditions. It has the strength to bear the dust, moisture, and heat.
Precautions about Buried Cables
In the same way, the Direct-Buried Cables or the underground cables must have the necessary insulations, extra covering and sheathing to protect the conductor from contacting the ground. For satisfactory transmission of the signal, it must remain protected from moisture, soil acidity, dampness, heat and other hazardous effects that the buried cables are prone to get damaged from. The cable is buried 24 inches in depth with the help of proper digging, to make sure that there is no electrical or water contact possible with the wire.
Some of the most important features that these Direct-Buried Cables Offers are: –
1) Long Distance Communication Channels
Buried Cables are actually used for long distance communication purposes. It is buried beneath the earth on a permanent basis and has a long life of about 25-30 years. Mostly, these buried cables contain optical fiber or coaxial in their construction beneath the outermost layer above it. To keep the transmission safe and secure, the Buried Cables are buried under the side roads and service lanes. So, that if a problem occurs, the whole structure of the road must not get damage.
2) Power transmission
Some projects which involve power transmission also uses direct-buried cables. But these electrical cables must meet strict electrical standards in order to be functional. Also, the installation of electrical cables underground is done only where the overhead cables are dangerous and impractical.
