GIS Switch Yard in Pakistan | ACCO’s Compact Power Solutions
Your textile mill sits on a tight plot in a busy part of Karachi. Land costs a fortune. You need a high-tension connection from K-Electric, but a regular switch yard would need acres of open space. You simply do not have that room. What can you do?
Think about a commercial plaza in DHA Lahore. The owner wants strong power backup. But every square foot of land is already used for parking or shops. There is no empty field left for electrical gear. A traditional outdoor yard is just not possible.
Gas-Insulated Switchgear (GIS) solves this problem. This technology shrinks a full switch yard into a much smaller space. It uses up to 90% less land than a conventional yard. It is safer, works better in dusty cities, and needs less upkeep over time. Ahmed Construction Company (ACCO) has over 25 years of experience designing these compact yards. From our main office in Gulberg-III, Lahore, and our branch in Karachi, we handle projects from 11kV up to 132kV. When you need a GIS Switch Yard in Pakistan, ACCO delivers a solution that fits your tight site and your budget.
What Is a GIS Switch Yard? A Simple Explanation
A GIS switch yard is just a smarter way to handle high-voltage electricity. Normal switch yards (called AIS) use open air as insulation. The circuit breakers, switches, and busbars are out in the open. They need huge gaps between them to stop electricity from jumping across. That is why normal yards take up so much land.
A GIS yard puts everything inside sealed metal boxes filled with a special gas called SF6. This gas stops electricity much better than air. So the parts can be packed very close together. The whole setup is much smaller.
For a busy city factory or a shopping mall with no spare land, GIS is often the only choice. Our GIS Switch Yard in Pakistan service covers the full job. We handle the electrical design, the concrete work, the protection systems, and the utility approvals. We also make sure the yard fits well with your building design and other site plans. Our architectural drafting team draws up clear layouts showing every module and cable trench.

Our Complete GIS Switch Yard Services
We cover every part of your GIS project. Below is a detailed breakdown of what we offer.
GIS Design for 11kV to 132kV
We design GIS yards for all common voltage levels. We work with parts from top brands like Siemens, ABB, and GE, as well as reliable local suppliers. Our design package includes single line diagrams, layout drawings, foundation plans, and protection studies.
- 11kV GIS: Good for shopping malls, small factories, and housing schemes.
- 33kV GIS: Ideal for textile mills, medium factories, and large hospitals.
- 66kV and 132kV GIS: Best for big industries, data centers, and utility substations.
- Hybrid GIS: A mix of GIS and AIS to lower costs while saving space.
Indoor or Outdoor Setup
You can put a GIS yard inside a building or outside with a weatherproof cover. We help you pick the best option. Indoor GIS works well when land costs are very high. Outdoor GIS with an enclosure works for most factory sites. We look at your space, budget, and security needs before recommending a choice.
Giving You a Clear Equipment List
We write detailed technical specs for every part. This includes circuit breakers, switches, current and voltage transformers, lightning arresters, and gas monitors. We help you buy from trusted suppliers. We also advise on SF6 gas handling and leak detection systems.
Protection Systems That Work
A GIS yard needs precise protection. Faults must be cleared in milliseconds. We design systems including differential protection (for busbars and transformers), distance protection (for incoming lines), and overcurrent relays. We also set up SCADA systems so you can monitor gas pressure and breaker status from a remote screen.
Safe Earthing and Lightning Protection
Even though GIS gear is enclosed, good earthing is still critical. We design earthing grids that safely carry fault currents away. We also protect incoming overhead power lines with lightning arresters.
Civil Work and Control Room
GIS modules need strong concrete foundations. They also need cable trenches and a control room for the protection panels. Our civil and structural engineers design all of this. We work with our architectural engineering team to make sure the GIS building fits your overall site layout.
Getting Utility Approvals for You
LESCO, K-Electric, and IESCO all approve GIS yards, but the paperwork is strict. We prepare everything: load forms, single line diagrams, protection studies, and building plans. We also talk to the utility engineers directly to answer their questions.
Watching the Installation
Putting together a GIS yard requires special skills. You need to handle SF6 gas carefully and align modules just right. We supervise the whole installation. We check for gas leaks, test the wiring, and watch the final commissioning. For extra clarity, we can create a 3D architectural walkthrough of your yard for safety training.
GIS vs. Old-Style (AIS) Switch Yards
This table shows why GIS is often better for tight city sites.
| Feature | GIS Switch Yard (ACCO) | Old-Style AIS Yard |
|---|---|---|
| Land Needed | Very little. Fits on small urban plots. | Needs acres of open land. Hard to find in cities. |
| Where It Goes | Inside a building or small outdoor enclosure. | Outside only. Needs a big fenced field. |
| Handles Dust and Pollution | Sealed shut. Dust and salt do not matter. | Open to the air. Dust causes flashovers. |
| Upkeep Needed | Very low. Just check gas every few years. | High. Needs regular cleaning and adjustments. |
| Safety for Workers | No live parts exposed. Very safe. | Live conductors in the open. High arc flash risk. |
| Upfront Cost | Higher (2-3x AIS). | Lower initial price. |
| Long-Term Cost | Lower because you save on land and upkeep. | Higher due to maintenance and land value. |
Our Simple 8-Step GIS Process
We follow a clear plan to deliver your GIS yard on time and on budget.
- Step 1 – See Your Site and Measure Space
We visit your location. We measure the available land. We check for dust, humidity, and access issues. We then decide if indoor or outdoor GIS works best for you. - Step 2 – Calculate Your Power Needs
We look at your current electricity use and future growth plans. We then recommend the right voltage level (11kV to 132kV) and GIS setup. - Step 3 – Talk to the Utility Company
We contact LESCO, K-Electric, or your local utility. We confirm they have capacity for your new connection. We also get their approved list of GIS brands. - Step 4 – Draw the Single Line Diagram
We create a single line diagram showing every GIS module. We run short circuit calculations. We set the protection relay values. - Step 5 – Choose the Equipment and Vendor
We write clear technical specs. We help you pick a manufacturer based on price, delivery time, and local support. We also check the vendor’s drawings and calculations. - Step 6 – Design the Layout and Foundations
We draw plans showing where each GIS module sits. We design the cable trenches, control room, earthing grid, and building. Our civil engineers size the concrete foundations for the heavy modules. - Step 7 – Submit Papers to the Utility
We package everything: the single line diagram, layout drawings, protection studies, and earthing calculations. We submit these to the utility and handle their questions. - Step 8 – Watch Over Installation and Testing
We supervise the assembly of the GIS modules. We check the SF6 gas filling and test for leaks. We test every wire and protection relay. Finally, we witness the utility commissioning.
Why Pakistani Clients Pick ACCO for GIS
Land prices in Karachi, Lahore, and Faisalabad have gone through the roof. A normal AIS yard that needs two acres might cost you millions just for the land. Industrial zones in DHA, Bahria Town, and Lake City have very little land set aside for power gear. Commercial plazas in Gulberg, Model Town, and Johar Town have no spare land at all.
This is why GIS is a game-changer. ACCO has helped many clients put switch yards where AIS was simply impossible. We have worked for Meezan Bank (city branches), textile mills in crowded Karachi areas, and commercial builders in Lahore. We also serve international clients in the UAE, UK, Saudi Arabia, Canada, and the USA who need our GIS skills for their own tight sites.

Frequently Asked Questions
1. What is architectural engineering in simple words?
Architectural engineering makes sure a building actually works, not just looks good. For a GIS yard, architectural engineering ensures the building fits the site, has good drainage, and has proper ventilation for the gas handling system.
2. How do I get a floor plan for my house?
Getting a home floor plan design from ACCO is very easy. Just call us at +92 322 800 0190 or visit our contact page. Tell us your plot size (5 marla, 10 marla, or 1 kanal) and your budget. We will visit your site in DHA, Bahria, Model Town, or anywhere in Pakistan, take measurements, and give you initial sketches within 7 to 10 days.
3. What is the difference between architecture and structural engineering?
Architectural design is about how a building looks and feels. Structural engineering makes sure the building stands up safely. For GIS yards, our structural engineers design the foundations for the heavy GIS modules, which can weigh several tons each.
4. Do you offer 3D walkthroughs?
Yes, we do. We create high-quality 3D architectural walkthrough videos of your proposed GIS yard. This is very useful because GIS gear is enclosed. A walkthrough helps your team learn the layout and find access routes before the equipment even arrives.
5. Can I really get a GIS yard in Pakistan?
Yes, absolutely. Top brands like Siemens, ABB, and GE supply GIS equipment to Pakistan. Local companies like Pak Elektron Limited (PEL) and Heavy Electrical Complex (HEC) also make GIS parts. Utilities like K-Electric and LESCO fully approve GIS yards. ACCO has experience with all of them.
6. Is GIS more expensive than a regular yard?
The equipment itself costs 2 to 3 times more than AIS gear. However, you save a huge amount on land purchase. In expensive city areas, the total long-term cost of GIS is often lower. Call us with your site details, and we will run a cost comparison for you.
7. Is the SF6 gas harmful to the environment?
SF6 is a greenhouse gas, which is a concern. But modern GIS equipment leaks very little—less than 0.5% per year. We design gas monitors and use proper handling procedures. If you are worried about SF6, we can also look into newer “clean air” or vacuum GIS technologies.
8. Can ACCO replace my old AIS yard with GIS?
Yes, we do this often. If your old AIS yard is failing, or if you want to free up land for other uses, we can design a new GIS yard in a small corner of your site. The new yard uses a fraction of the land. The remaining space can then be used for parking, a new building, or sold off. We handle the whole changeover, including temporary power during construction.
