Why are there balls/connectors on the electrical cables?

I always have this question as I travel along the highway.

Answer from an electrical engineer:
Reduce resonance on the power lines due to strong wind

And it is called a damper..
Also, there are also bird deflectors installed at other countries..

An afternoon at Dannok

Living at the northern side of Malaysia makes it really convenient and easy to go 'overseas'. For us, going to our neighboring country, be it Thailand or Singapore by land or by flight is really easy.

The funny part is, I already blogged about it two years ago. The immigration complex in Malaysia is new. I nearly couldn't recognize it, while passing to get our passport checked. As I didn't want to drive over, we parked our car at the Zon Duty Free. As I entered, I took the wrong ticket (which parking rate is RM3...
