Pooya Gharb | OPGW

The OPGW cable consists of one or more aluminum or steel tubes containing fiber optics & ACS wires in the 1st  layer & a combination or each of aluminum alloy, aluminum & steel wires in the other layers according to the type of electrical & mechanical features.

Number of fiber optics in the steel tube varies from 1 to 12,24,48 cores or more based on the customer needs .

The OPGW cable is installed at the highest spot of the transmission tower. Multi or single mode fiber optics is used to design & produce the OPGW cable. Single mode is used for distances longer than a kilometer with high broad band & multi mode for the shorter distances than a kilometer & lower broad band.

OPGW cable is alike to the shield wire or ACSR conductors & is used either to replace with the shield wire in the old power transmission lines or as bi functional product in the new ones.

Audio-visual data transmission by the fiber optics & protect the electric current phase lines against the short circuit currents & sudden currents of thunders & earthing these currents via the transmission towers are some other usage of the OPGW cable.

Feature & Advantages (comparing with ground cables):

-Low installation cost

-No damages loss

-Data transmission development

Since audio visual data transmission via ground cables in some areas like mountainous is costy,so; using OPGW cable is a cost reduction.
