Cold Shrink vs Heat Shrink: Which XLPE Kit Is Best for Indoor, Outdoor, or Explosive Areas?

When it comes to XLPE Cable Termination Kits, one question lingers around our minds: Should we go for Cold Shrink or Heat Shrink? The answer isn't as simple as” you think. 

 

Reason? One cannot say which is better than the other." It is all up to you and where and how you use it, whether it is indoors, outdoors, or even in explosive conditions.

 

Suppose you are going to have a large, heavy piece of wire conveying a large amount of electricity. That end of that wire is kept open.  Do you think it is safe? No. That's why experts use XLPE Cable Termination Kits. 

What is an XLPE Cable Termination Kit?

XLPE Cable Termination Kits are a type of device designed to cover the ends of power cables. So, this ensures proper electricity flows safely while protecting people and machines.

 There are two types of these kits:

1. Heat Shrink
2. Cold Shrink. 

Which one should you choose? 

Heat Shrink Vs Cold Shrink

●       Heat Shrink XLPE Kits need a heat gun. You need to warm them up, and they shrink tightly around the cable. They use heat guns to shrink the tubing around the cable. 

●       Cold Shrink XLPE Kits don’t need any heat. You pull out a plastic tube, and they shrink on their own. They are pre-stretched and shrink automatically when the inner core is removed—no heat needed.

 This may sound simple. However, where you use them, indoor, outdoor, or explosive areas, makes a difference.

Indoor Environments

Heat Shrink Kits are the preferred choice for indoors because the air is dry, and there is no rain. You can use the space safely.  These kids are perfect for Office buildings, Control rooms, or Switchboards. Their quality includes the following:

●       Strong and tight fit

●       Lasts a long time

●       Easy to find and affordable

Outdoor Environment

Choose Cold Shrink Kits for the outdoor environment. Why? Outdoors can be messy: rain, sun, wind. Cold shrink kits don’t need electricity, so they’re easy to use anywhere. They are perfect for Solar panel sites, Electric poles, substations, and switchyards. Their quality includes the following:

• No fire or spark needed
• Fast to install—just pull and go
• Stays strong in hot sun or heavy rain
• Great for faraway places without power 

These XLPE Cable Termination Kits are a little more expensive. You need to keep it safe. Don't let it shrink before use. 

Explosive or Hazardous Environments

In an explosive or hazardous environment, go for Cold Shrink Kits because in places like oil plants or gas factories, using fire or heat is dangerous. One spark, and boom! Cold shrink kits keep things safe. These kids are perfect for oil refineries, Gas stations, and Chemical factories. Their quality includes the following:
