Turnkey Housing Society Electrification — pad-mounted substations & underground grid.
Modern master-planned residential communities demand clean, reliable, and aesthetically integrated underground electrical networks. TransfoLine delivers complete Turnkey Town Electrification: 400–630 kVA pad-mounted transformers, 11kV Ring Main Units (RMU), underground cabling, and official WAPDA, LESCO, IESCO, and CDA approvals.
Engineered for absolute industrial reliability.
TransfoLine brings 18+ years of field engineering and 500+ completed substations across Pakistan.
Comprehensive technical execution scope.
Pad-Mounted Transformers (400–630 kVA)
Compact, dead-front oil-immersed distribution transformers engineered for outdoor pad mounting with integrated cable compartments.
SF6 Ring Main Units (RMU)
Compact 3-way and 4-way 11kV switchgear units with vacuum circuit breakers for safe underground feeder loop switching.
Underground 11kV Cabling & Trenching
Laying 3-Core armored 11kV XLPE copper power cables in reinforced concrete conduits with warning tiles and route markers.
Low-Tension Feeder Pillars
IP55 weatherproof outdoor distribution pillars feeding street circuits and individual residential plot meters.
From concept to energized power.

Frequently asked questions.
Common questions about this service. Call our engineering team for anything else.
SUBSTATION SIZING What size transformer is recommended for residential housing blocks in Pakistan?
For modern housing societies with air conditioning loads, developers typically install 400 kVA or 630 kVA pad-mounted distribution transformers, with each unit feeding 40 to 70 residential houses via underground feeder pillars.
RMU FUNCTION What is a Ring Main Unit (RMU) in housing society electrification?
An RMU is a compact, sealed switchgear unit that allows an 11kV underground cable loop to feed local transformers while maintaining the ability to isolate faulty sections without cutting off power to the rest of the housing society.
CIVIL WORKS Does TransfoLine handle underground cable laying and civil pad construction?
Yes. Our turnkey town electrification service includes civil excavation, cable trenching, chemical earth pit boring, pad concrete pouring, switchgear mounting, and utility commissioning.
