Fuses and Links
Fuses and Links
(OP)
I am a relatively new engineer working in the transmission and distribution of electricity. When preparing wiring schemes i know that electrical equipment is protected by a fuse and link. I know that a fuse blows when the supply exceeds a certain limit but can someone give me a good explanation of what the link is there for.

In simple, Fuses are used to protect the equipment and link are used to isolate the equipment.

For typical <38kV overhead distribution systems on the North American continent, expulsion fuses are very common. ANSI references are C37.40-series standards.
Literature from one producer of many is…

Fuse links when melted open a fuse cutout switch.
Here's an ABB cutout switch.

Thats a very long link- you can find similar information by googling up "fused cutouts"
Below is another good link -worth gettin if your into T&D.

If that one doesn't work google up "ABB, Hard to Find Information About Distribution Systems."

Highly recomended files (downloadable) worth a read from Areva (It is the old PRAG-book):

As a last note a just want to say that this site (www.eng-tips.com) is one of the best places to visit to find some info regarding engineering. Defenitely worth a visit every day. It helped me quite a lot with some problems I've encountered in my workplace.
