Underground Cable Laying Machines in India: Models, Tenders, Companies and News

Underground cable and optical fibre (OFC) laying runs on small digging machines: mini excavators and backhoe loaders cut the trench, skid steer loaders backfill it, pick and carry cranes handle the heavy cable drums and tandem rollers close a road cut, while horizontal directional drilling rigs take the cable under roads without opening them. This page keeps those machine classes, the models buyers ask about, open tenders, the states laying the most fibre, the main companies and the latest news in one place.

Which machine is used for underground cable laying?

No single machine lays underground cable. The method picks the machine, and India’s code for power cables, IS 1255:1983, names four ways to open the ground: by hand, by mechanical excavation, by thrust boring and by trench ploughing. It adds that only the first two are possible in cities and towns, where other services are already buried.

So most cable and optical fibre (OFC) work in India is open trench work: dig, bed the cable in sand, cover it with tiles or bricks, backfill, restore the surface.

Method Where it is used Machines that do it
Open trench Footpaths, road shoulders, colony lanes, factory and campus sites Mini and small excavators or backhoe loaders dig; skid steer loaders and backhoe loaders backfill; a tandem roller restores a road surface
Thrust bore or horizontal directional drilling (HDD) Under a road, rail line, canal or busy junction that cannot be opened HDD rigs push a bore under the obstacle and pull a duct back through it. Excavators dig the entry and exit pits.
Trench ploughing Open country with no other buried services nearby Cable ploughs and chain trenchers cut a narrow slot and lay the cable in one pass

Depth is rarely the limit. IS 1255 puts the top of a power cable 0.75 to 1.05 metres down, well inside what the smallest machines reach, so width matters more (see digging depth by machine size). Backfill at the bottom of a narrow trench is firmed with an excavator compaction wheel.

HDD rigs, cable ploughs, chain trenchers and cable winches are not listed here.

Where is the most fibre being laid in India?

In a written reply to the Lok Sabha, the communications ministry gave the optical fibre laid in each state from April 2022 to March 2025, and each state’s total by December 2025 (Press Information Bureau, 11 February 2026). These eight laid the most:

State Fibre laid, April 2022 to March 2025 Total fibre, December 2025
Tamil Nadu 1,02,865 route km 3,08,907 route km
Kerala 88,591 route km 2,59,252 route km
Andhra Pradesh 81,307 route km 2,51,753 route km
Maharashtra 70,178 route km 4,06,637 route km
Telangana 65,691 route km 2,37,946 route km
Punjab 60,654 route km 1,97,105 route km
Uttar Pradesh 55,672 route km 4,06,697 route km
Rajasthan 45,058 route km 2,39,458 route km

India laid 8,50,284 route km in those three years. The figures cover every telecom operator, BharatNet included, and do not split buried fibre from fibre on poles.

Who are the main cable and fibre laying companies in India?

The work comes from telecom operators, public sector network builders and cable makers with project arms. The list is alphabetical, not a ranking.

Company What it builds or runs
Bharat Sanchar Nigam Limited (BSNL) The state-owned telecom operator, and one of the three public sector companies that built Phase-I of BharatNet, the rural fibre network
HFCL Makes optical fibre cables, including microduct and FTTH cables, and offers rural broadband solutions for BharatNet and railway communication systems
KEC International An EPC company whose businesses include power transmission and distribution, railways, civil works, oil and gas pipelines and cables
KEI Industries Makes extra high, medium and low voltage power cables and runs an EPC business
Polycab India Makes wires, cables and cable accessories and runs an EPC business
Power Grid Corporation of India A central public sector company, and the third of the three given BharatNet Phase-I, with BSNL and RailTel
RailTel Corporation of India A public sector company under the Ministry of Railways that lays optical fibre along railway tracks, using the railways’ right of way, and runs a fibre network across India
STL (Sterlite Technologies) Makes optical fibre and fibre cables and offers fibre roll-out services

The three BharatNet Phase-I companies are named in the parliamentary standing committee’s report on BharatNet, as summarised by PRS Legislative Research; the other lines are from each company’s own website.

Which guides explain this work?

Start with digging depth by machine size and the compaction wheel, then the mini excavator and backhoe loader guides.

What else does a cable laying contractor need?

Money, cover, parts and tools for the same job.

Frequently asked questions

Which machine is used for underground cable laying?

It depends on the method. In towns most cable and fibre goes in an open trench, dug with a mini excavator or backhoe loader and backfilled with a backhoe or skid steer loader. Roads are crossed with a directional drilling rig, and open country can be cable ploughed. Those rigs and ploughs are not listed here.

How deep is an underground power cable laid in India?

IS 1255:1983, the code for power cables up to 33 kV, gives the minimum depth to the top of the cable as 0.75 m for low voltage and control cables, 0.9 m for 3.3 to 11 kV cables and 1.05 m for 22 and 33 kV cables. Road crossings and railway level crossings both call for 1.0 m.

Can a mini excavator dig a cable trench?

Yes, and it is usually the right machine. Even the smallest mini excavators dig deep enough for a cable. A narrow bucket and a machine compact enough to work along a footpath without blocking it matter more.

How is a cable laid across a road without digging it up?

Through a duct. A thrust bore or directional drilling rig makes a hole under the road, a duct is pulled through and the cable is drawn into it. IS 1255 asks for ducts at road and railway crossings, plus spare ducts for later cables.

How is a cable trench filled and the road put back?

The cable is bedded in sand and covered with tiles or bricks. A backhoe or skid steer loader pushes the fill back in layers, a compaction wheel on an excavator firms it, and a tandem roller rolls the new road surface.

Where can I see cable and fibre laying tenders?

Open underground cable and optical fibre packages from our tender desk show in the tender list on this page, closing soonest first. The tenders page carries every open tender.
