The ‘system’ works: Safe & secure electrical connections
30Sep
There are manufacturers of crimp compression terminals from all over the world. Each will manufacture their lugs to different dimensions, using a variety of material standards.
In the final instalment of an exclusive three-part "tools special", Klauke asks, as the dimensions of the tube can vary greatly between manufacturers for the same cable size, how do you know the compression crimp that's made is safe and secure?
Quite often, contractors and installers will see the cable lug as a small, unimportant part of the entire build, with little time spent considering the consequences. If this component is not correctly specified and installed using the correct tools, the cost to rectify the equipment or send engineers to the site will far exceed the cost of using a correct crimping ‘system’ in the first place.
More often today, the crimp style made to install cable lugs is hexagonal (rather than indent). This means that when the jaws of the crimping tool have met, there is no further compression of the cable lug. So, the correct selection of cable lug is very important to match the crimping tool in use and guarantee the connection made is safe and secure.
The only way to ensure a safe termination is to use a matched system where the same manufacturer’s products – a cable lug, die set and crimping tool – are used throughout the connection. This is the recommendation throughout the world and will give you peace of mind that the connections made will be safe for years to come.
