SS Glands for Single Core Cables

03/14/2012 4:52 AM

Non magnetic gland plate is used for Single core Cables. But these cables have got SS Glands. Whether the same is ok?

is there any relation between magnetism with insulated cable? don't aware of it !!

Cable gland material selection is based on Surroudings & environment such as hostile salt water situation at offshore area, high & low temp. area, corrosive & acid vapourised extremes etc...................

If by SS you mean stainless steel, you have your answer. Stainless steel generally is not magnetic.

A 3-, 3½- or 4-core cable will carry all three phases (and neutral also in the latter two cases). The vectorially summed up magnetic field around such a cable is zero. So, the gland and gland plate can be of any steel, nothing will happen.

Not so for single-core cables, which carry only one phase. The magnetic field around this can heat up normal steel to red heat. So, one needs non-magnetic glands. Smaller cables can manage with brass glands, but larger ones may require the stronger stainless steel glands. Please note, stainless steel is not completely non-magnetic.

To avoid circulating currents due to induced emfs due to stray circultaing currents
