OUTDOOR CABLE WIRE

DROP WIRE

In a telecommunications network, a drop wire is the portion of a device directly connected to the internal station facilities, such as toward a telephone switchboard, toward a switching center, or toward a telephone exchange. A drop also can be a wire or cable from pole or cable terminus to a building, in which case it may be referred to as a downlead. These cables may be reinforced to withstand the tension (due to gravity and weather) of an aerial drop,as in "messenger" type RG-6 coaxial cable, which is reinforced with steel messenger wire along its length.

SUMMARY OF DROP WIRE...

Drop wire are widely used for extending the telephone circuit from aerial distribution cable terminating to building entrance protection or designed for extension to subscriber.
This drop wire are constructed by using:
     conductor    >  Hard drawn copper wire at the diameter of  0.8, 0.9, and 1.0 mm
     insulator      >  Two hard drawn copper wire parallel to each other  is coated with polyethylene 

underground cable

 single mode 12 core

TECHNICAL DIMENSION

Electric power can be transmitted or distributed either by overhead system or by underground cables. The underground cables have several advantages such as less liable to damage through storms or lightning, low maintenance cost, less chances of faults, smaller voltage drop and better general appearance. However, their major drawback is that they have greater installation cost and introduce insulation problems at high voltages compared with the equivalent  overhead system. For this reason, underground cables are employed where it is impracticable to use overhead lines. Such locations may be thickly populated areas where municipal authorities prohibit overhead lines for reasons of safety, or around plants and substations or where maintenance conditions do not permit the use of overhead construction.

SUMMARY OF UNDERGROUND CABLE...

The cable consist of a central loose tube, filled with a synthetic oil based jelly, non-nutritive to fungus, electrically non-conductive, homogeneous and free from dirt and foreign matter, containing up to 12 optical fibre. Two Fiber Reinforced Plastics (FRP) elements are longitudinally applied parallel with the tube, and outer black PE sheath, UV resistant.
