TNB CSU Plinth (Precast Concrete Compact Substation Unit)

⚡ TNB CSU Plinth

🧱 Precast Concrete Foundation for Compact Substation Unit (CSU)

TNB CSU Plinth is a heavy-duty precast concrete base specially designed to support Compact Substation Units (CSU) used in electrical infrastructure projects across Malaysia.

In simple terms, this product acts as the foundation platform for your substation system. Instead of casting concrete on-site—which can be time-consuming and inconsistent—this plinth is manufactured in a controlled factory environment, delivered ready to install, and built to meet TNB requirements.

For contractors, developers, and engineers, this means faster installation, better quality control, and long-term reliability. Contact Buildmate Home Living Sdn Bhd

📌 What is a CSU Plinth? (Simple Explanation)

A CSU plinth is a precast reinforced concrete base that supports electrical substation equipment.

Think of it like this:

👉 If the substation is the “heart” of your electrical system,
👉 then the plinth is the strong foundation that holds everything in place safely.

It also comes with built-in cable openings (ductways) and removable covers, making it practical for both installation and future maintenance.

📦 📊 Complete System Specifications

This is not just a single block — it’s a complete modular system designed for real site conditions.

🧱 Main Plinth Unit

• Size: 6250 × 2550 × 1350 mm
• Quantity: 1 unit
• Weight: Approx. 18 tons

👉 This heavy-duty structure provides the main load-bearing support for the substation.

🧩 Removable Cover Slabs (Cable Access)

• Slab A: 1100 × 150 × 100 mm (15 pcs)
• Slab B: 850 × 150 × 100 mm (15 pcs)
• Slab C: 1700 × 150 × 100 mm (1 pc)
• Slab D: 1700 × 1240 × 150 mm (1 pc)

👉 These covers are designed to be easily removed, allowing:

• Cable inspection
• Maintenance work
• Future upgrades

🚧 Protection System (Bollards)

• Bollard Size: 160 × 160 × 1000 mm (14 units)
• Footing Size: 375 × 375 × 450 mm (14 units)

👉 Installed around the plinth to:

• Protect against vehicle impact
• Improve site safety
• Prevent accidental damage

🔧 Key Technical Features

🔌 Built-in Cable Ducting

The plinth comes with multiple duct openings, making cable routing:
✔ Cleaner
✔ Faster
✔ More organized

No need for excessive hacking or modification on site.

🦾 High-Strength Precast Concrete

Manufactured using reinforced concrete to ensure:
✔ High load-bearing capacity
✔ Long service life
✔ Resistance to weather and site conditions

🏭 Factory Quality Control

Produced under ISO 9001:2008 standards, ensuring:
✔ Consistent quality
✔ Accurate dimensions
✔ Reliable performance

🏗️ Site Preparation Requirements

Because the plinth weighs around 18 tons, proper base preparation is very important.

📐 Recommended Setup:

✔ Crusher Run Layer: 300 mm (fully compacted)
✔ Sand Bedding Layer: 100 mm (levelled surface)

👉 This ensures:

• Stable support
• Even load distribution
• Reduced settlement over time

🔧 How It’s Installed (Simple Site Flow)

1️⃣ Prepare base (crusher run + sand layer)
2️⃣ Deliver plinth to site
3️⃣ Lift and position using crane
4️⃣ Connect cables through ducting
5️⃣ Install removable slabs
6️⃣ Set up bollards for protection

👉 Compared to traditional casting, this method is much faster and cleaner.
