International Connectivity

POWERGRID is now offering Domestic leg for India –

Bhutan & Bangladesh International Connectivity on

two different routes for high reliability.

1. Bongaigaon(India)–Galephu (Bhutan) Link (50Km)

2. Siliguri (India) – Malbase(Bhutan) Link (98Km)

3. Bharampur(India)–Bheramara(Bangladesh)Link(

102 Km)

POWERGRID is also in the process of establishing

International Connectivity to other neighboring

countries Viz. Srilanka (thru undersea cable & OPGW),

Bangladesh & Nepal through its power transmission

network.

Optical Ground Wire (OPGW) : Ground wire of

existing transmission line is replaced by OPGW cable

having fibres inside and ground wire outside.

Wrap Around : FO cable wrapped around ground

wire.

All Dielectric Self Supporting (ADSS) : FO cable

strung separately on the transmission towers as a conductor.

Installation

― OPGW is most suitable where Ground wire is available.

― Existing ground wire (9.75/11 mm) is replaced by OPGW (12-13.5

mm)

― The loading of OPGW is taken care in case of new transmission

line design

― ADSS is additional wire along the transmission line (13-15 mm)

― Installation of these cables on existing transmission lines may

require tower analysis and tower strengthening

― Installation is carried out live line

― OPGW is best suitable proven technology for EHV lines

ADSS is suitable in lower voltage lines

Overhead OFC and its Installation

24


Telecom networks on Transmission Infrastructure

―Sturdy & secure

―rodent menace free

―vandalism proof

Right of Way (ROW) readily available for installation of OPGW on its transmission lines

―No forest Clearance are required

―Faster Roll-out, Mostly Live line installation

Availability of Telecom Network over Transmission system- higher than 99.97%

Only utility in the country providing overhead fiber optic cable for NLD telecom networks

Only reliable network in remote areas viz. J&K and NER
