Project Description:

Qualification and awarding this project through tendering procedure and investigation to prepare required optical fiber communication system for Damavand Power Plant as the biggest Power Plant in Middle East, is one of our brilliant successes in our done projects as well.
At the time of project this project was very important and in top urgent classification and we could complete our scope of work very earlier than others. As soon as completion of other companies scope of work in passive parts of projects our system start to work and from that time it is in service.
Very soon this point became one of the most important communication nodes based on its place of work that is one of critical communication bottle necks in TAVANIR. Nowadays all traditional communication traffic for PABX and PLC (Power Line Carrier) systems at that area is supported by prepared required interfaces with installed system such as Djalal Substation PAX connection up to Social Operation Center, same for Ahowan Substation including its DTS, required SOC data transfer through Analog Modems received from PLC system, Preparing required Data Tunnel to support Ethernet network to build WAN in cooperation with Tehran Regional Electrical Co. in Sadat Abad Building that support both their computer network and internet, Forwarding all SCADA data to SOC from Damavand P.P and 400KV substation, Ahowan 400 KV Substation and Damghan 400KV Substation.
On time activities and good project management make end user to award us official letter about our good performance action.

Project Description:

Installation of Optical Guard Wires over 150 km of 400kv line with metal lathetic and none metal towers between Ardebil(Sabalan) power plant and Azerbaijan border in fully outage condition was the scope of work.
Based on tight time schedule for installation and many difficulties to prepare required outages we prepare a letter to suggest our client to let us to work in Live Line condition and Install OPGW over all crossings with 20kv, 63kv, 230kv and 400kv lines.
With our client acceptance and preparing required permit we start to work in Live Line condition and succeed to complete our scope of work before due date. In this regards the client issues attached official letter of our good performance activities also.
