What Are the Different Termination Kits for Cables?

At the end of the cables where a conductor stops, there are several safety concerns. This happens because of the lack of insulation, strain at joints, and corrosive conditions. The performance of the cable not only depends on the purity of the conductor, resistance, and insulation, but also on how it is finished at the ends. When there is moisture entry, stress concentration, or insulation breakdown at the end of the cable, the conduction eventually stops, and the whole system fails. This is where TerminationKits for Cables come into play. These kits are the solution for the lack of electrical insulation at the ends, mechanical strength, and sealing from environmental stressors.



Types of Termination Kits for Cables

There are mainly 3 types of termination kits for cables. These are required as per different operating conditions, voltage levels, and installation environments, which require different types of termination solutions.

Heat Shrinkable Termination Kits

Heat Shrinkable termination for cables is the type of termination kit that uses a heat-sensitive material that shrinks onto the ends and seals the joint or terminals. The material of the tube can be polyolefin, silicon rubber, or nylon. These have excellent dielectric strength and mechanical strength. Many of them have flame-retardant properties as well. They are anti-tracking and temperature-resistant as well. The heat-shrinkable termination kits for cables contain heat shrink tubes for insulation, anti-tracking, breakout; connectors/ferrules, and mastic and tape for stress control. A heat gun is used to apply heat to the tubes evenly, and this whole operation is performed by the experts.

Cold Shrinkable Termination Kits

The cold shrinkable termination kits for cables are the ones that don’t need any heat source to create a termination. It basically contains a pre-expanded tube that retains its form when the plastic core is removed. It gets into its original size and wraps around the cable. The tube has elastomeric properties due to which it remains in its form for many years under harsh environmental conditions. The shrinkable material of the sleeve/tube is silicone or EPDM rubber. The kit contains an elastomeric sleeve, an inner plastic core, stress control cones, sealing components, grounding connections, and a lug. This type of termination is applicable in confined spaces, underground installations, and live substation environments where open flames or heating tools are restricted.

Pre-Moulded Termination Kits

The pre-moulded termination kits are engineered in the factory to reduce the on-site assembly and minimize the errors in installation. These are reliable insulated ends for the power cables in various high and low voltage applications. These kits are designed to fit with the specific cable sizes and voltage classes. They have a compact design, which makes them suitable for limited spaces.

Conclusion

To select the right termination kits for cables, consider the cable type, conductor size, insulation material, voltage rating, and installation environment. A well-designed kit is durable, easy to install by the experts, minimize maintenance work and ensures electrical continuity. These are not just an accessory but an integral part of the overall electrical network.

Need for Heat Shrinkable Cable Termination

In medium to high voltage electrical grids, there are many variables to take care of. Insulation is one of them. Even the slightest leniency in insulation can lead to costly downtime and accidents, because of high voltage operations. Heat Shrinkable Cable Termination is one of the methods of insulating cable connection reliability. It is not only essential for electrical insulation but also protects against environmental factors, enhances mechanical strength, and durability of the cable. These are commonly employed in power distribution networks, industrial settings, power generation, renewable power industry in various types and configurations of power cables. Method of Heat Shrinkable Cable Termination Heat shrinkable termination is basically a method of connecting two cables and creating an insulating seal to avoid leakages and protect from degrading agents. In this method, a heat shrinkable material is used to seal off the connection between the two cables. Here’s how it works...

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

Image
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: Heat Shrink Cold Shrink.   Which one should you choose?  Heat Shrink Vs Cold Shrink ●       ...

Avoid These Mistakes When Using Heat Shrinkable Cable Termination

Image
  Cables are connected to various fixtures like meter boxes, isolators, power sources, and control panels through a special method known as termination. It is a necessary way by which the connection is secured. At high voltage transmission, the potential of the charge travelling through the cable is very high, which can lead to short circuits and overvoltage through the air when the conductors are unprotected. Moreover, when the cables are connected to devices like a bus bar, the strain on them is quite high, which cannot be handled by the cable because of its low mechanical strength. Therefore, Heat Shrinkable Cable Termination is used to protect cables and make them survive various environmental conditions for a long period. But heat shrink is not an unskilled method. It requires sufficient knowledge and skills to carry out the process safely. Here are the common mistakes that one must avoid while using heat-shrinkable cable termination: Poorly Prepared Cable Before applyi...
