When engineers make Ketupat

Ahh...don't you just love the details engineers put into things you thought were plain simple.


Malaysia's Ketupat

The Ketupat - type of rice dumpling or rice cake - is one of the popular Malay delicacies that have been listed as heritage food in Malaysia. The Ketupat, when translated in English, is literally a made from glutinous rice.

It’s usually wrapped in a triangular shape using the leaves of the fan palm Licuala. Wrapped in a pouch of woven palm leaves, is then boiled for hours. As the rice cooks, the grains expand to fill the pouch and the rice becomes compressed into soft cakes.

In Malaysia, Ketupat is also traditionally served by Malays at open houses on festive occasions such as Idul Fitri (Hari Raya Aidilfitri).

XLPE insulated cable - Current rating

I am currently working on a pump replacement project; specifically reviewing the motor control centre with the view to upgrade them from the current resistance starter to variable frequency drive, VFD. I've gotten some quick references and information from a couple of sites that would be handy for my personal use and I hope the website owners are fine with it.

The resistance starter was fine, reliable and lasted but with the availability of VFD at reasonable price, coupled with the prospect of energy saving for such starter, it is a viable option for the premium efficiency motor manufactured by Nidec.

Exactly my interest is on the 630mm², XLPE 1/C, multicore 300mm² and 400mm² armoured cables.


For more info of this cable, see link at the bottom of the article.

Hopefully this job will be completed by year end and I can have some time blogging again.
