So, 75% of cable failures happen at the termination point? (Source: ResaerchGate). Yet, the reality is that most of these problems originate from poor installation or the omission of crucial steps during the setup process.
That's why installing your termination kit properly is essential for your system. Let us understand the installation process through this blog, which provides clarity and eliminates confusion, ultimately leading to perfectly installed terminations and reduced failure rates.
Let's dive in!
What is a Termination Kit?
First things first. Let's start with the basics.
The Three-Core 33kV Termination Kits are designed for medium-voltage power cable installations, specifically for three-core, armored cables. They offer excellent electrical performance, mechanical protection, and environmental sealing for reliable, long-term operation.
Utilizing state-of-the-art heat shrink technology, the kits ensure a secure fit and mitigate problems such as partial corona discharge and surface corona, thereby improving system efficiency in challenging situations.
Heat shrink termination kits are the most popular types, known for their insulation, stress control, and environmental sealing. So, if you are wondering how to install a termination kit, buckle up. We are about to unlock the process like never before.
Step-By-Step Installation of a Heat Shrink Termination Kit
1. Safety First—No Exceptions
Look, when it comes to electricity, this isn't the time to take risks. So:
- Make sure to switch off the power and double-check it's off.
- Do wear an appropriate PPE—gloves, goggles, arc-rated clothing.
- Keep your work area dry, clean, and well-lit.
2. Prepare Your Cable
Always refer to your termination kit manual, as each kit is slightly different.
Here's what to do:
- Strip the cable to the specified lengths as instructed.
- Carefully remove the outer sheath, semi-conductive layers, insulation, and conductor shielding.
- Use a cable knife or peeling tool.
3. Slide on the Heat Shrink Components
Don't be that person who skips sliding the sleeves on first—
- Start by sliding the heat-shrink components, such as stress control tubes, insulation tubes, and outer sealing sleeves, over the cable before making any connections.
- Keep them safely up the cable until you're ready to shrink them into place.
4. Crimp It Real Good
It's time to connect the cable to your equipment.
- Use a proper crimping tool to attach the lugs to the conductor.
- Make sure it's tight, secure, and professionally done.
- No loose lugs allowed—this is medium-voltage power we are talking about!
Once done, clean the exposed insulation area and prepare for the final heat-shrink installation.
5. Heat It Like You Mean It
Now, the fun part—watching everything shrink to perfection.
- Starting with the innermost layer—the stress control tube, apply heat evenly using a gas torch.
- Move in a circular motion, avoiding overheating a specific spot.
- As each layer shrinks, it seals and grips tight. Once everything's in place, let it cool.
Note: The above steps are a simplified version of a more comprehensive 25-step procedure that includes detailed measurements, tool specs, and additional considerations for indoor and outdoor installations.
